MY TRUCK NO LIKE START!!

[tomaitz]

I HAVE A 97 CHEVY S10 4X4 WITH A 4.3 V6 MOTOR IN IT.. AND IT DOESN'T WANT TO START!! I TRIED CHANGING THE FUEL FILTER AND THE FUEL PUMP ALLREADY BUT STILL MY TRUCK NO LIKE START!! I DID CHECK MY RELAYS ALREADY AND TRIED SWITCHING THEM.. TO SEE IF MY TRUCK STARTS BUT HAVE NO LUCK!! THE CHECK ENGINE LIGHT IS ON.. AND THE BATTERY LIGHT IS ON.. WHAT IS THE PROBLEM OF MY TRUCK..? CAN YOU GUYZ GIVE ME SOME HELPFULL ADVICE...

[csl2006]

what is it exactly doing? is it cranking over or not? Does it spit and sputter or attempt to run when you crank it over? Or just turn without fire?

[tomaitz]

THE TRUCK TRY'S REALLY HARD! BUT IT CAN'T START!!

[tomaitz]

THE TRUCK CRANKS!!

[tomaitz]

I READ SOMETHING IN HERE.. THAT THEY WENT CHECK THEIR ECU OR REPLACE THEIR ECU AND THE TRUCK HAD RUN GREAT AFTER.. WHAT IS ECU ANYWAY..? AND WHERE CAN I FIND IT..?

If the check engine light is on....your truck is telling you that theres a problem. Maybe its related to your problem. Get a scanner and check the codes.

[tomaitz]

any other suggestions..?

[spideyjected]

Make sure it has solid spark AND that the engine is in time.

how can i make sure that my truck has a solid spark..?

[spideyjected]

Remove the coil wire from the coil tower and crank the engine over. It should make a good CRACK sound as the coil fires.

Also, to make sure the engine is at least somewhat in time. Remove a spark plug that is easy to get at, "I'd use #1, Drivers side front". Ground the spark plug to the engine where it can be seen. Then crank the engine over "with the coil hooked up" and watch for the spark plug to spark. The plug should fire about the same time the engine's starting sound changes because there will be no compression in that cylinder.

i never really did do these things before.. but sounds like its too complicated to me..

wat about scanning the computer.. and check it for some codes..? wat kind of scanner tool should i buy..? and where can i get it..?

[spideyjected]

You can try a scan tool, but it won't neccesarily detect an ignition problem if that is the case.

[spideyjected]

Just go out and pull the wire that goes from the distributor to the coil off of the coil. With the wire off, crank the engine over. If it makes crack, crack, crack noise, the coil is probably good.

[tomaitz]

ok.. i think should really try that one before i buy a new coil.. how much does a new coil cost anyway..?

[Big Mack Daddy]

Autozone has them for $35.99

['94 Big Blaze]

anything yet ?

[tomaitz]

Autozone has them for $35.99

wat about napa and checkers you think they get one too..?

[tomaitz]

anything yet ?

nope!! not at the moment i gotta drive to my friends house to work on my truck!!:( and im so :confused: thinking wat is wrong with my truck!! he just cranks like normal but no like start!!:(

[Big Mack Daddy]

napa is $57.49

[tomaitz]

how you know all this kind stuff..? you work for them.. or something..? haha.. just asking..

[tomaitz]

wat else you think is wrong with the truck.. should i check the pressure on my fuel lines.. i read it somplace in here that its gotta be 55 ot 60 psi something like that!! wat kind of tools do i need.. all i know is that i need a fuel pressure gauge.. right..?

[trusconi]

to remove the coil wire you should not need any tools.

['94 Big Blaze]

might want to take it to a pro, you may blow the damn thing up if you get to messing with the fuel pressure.

[spideyjected]

I've been around cars all my whole life and it took me almost a year to get mine to start. Heck it could be anything really. You can get a fuel pressure gauge to test with. But BE CAREFUL! If you are new to this stuff, get a manual first.

[BigTruckDrivah]

WHEN YOU TYPE LIKE THIS, it kinda feels like your yelling at us bro. .







BFH?

[spideyjected]

And I am not saying throw parts at it either. Just offering some advice on possible tests. You should be able to hook up a fuel pressure tester somewhere, but I'm not sure exactly where on the newer engines. But definately if you feel overwhelmed by it, then probably you'll either need a helper with more experience or even a professional.

[tomaitz]

that's what im thinking right now.. maybe i should just bring to my mechanic friend and get charged high!! i don't really want to mess around with the truck specially when you get close to the fuel tank or something to do with fuels..

wow did you say a year..? or i just misread your typing.. hmm.. i guess not!! but wow that's a long time.. so wat was wrong with the truck after all this time..

BFH?

ooopss.. my bad!! didn't know that.. but it's good to know though thnx!! and wat is BFH stands for anyway..?

[tomaitz]

i think i really shoud buy a OBD2 scanner for the truck cuz the truck engine light is on.. and one thing that i found today is that.. the fuel pump in my truck is not even turning on!! i took out the fuel filter and turn the key to see if it's spitting gas but nothing came out!! im thinking should i may a toggle switch for my fuel pump.. wat do you guyz think..?

[spideyjected]

2 primary things were wrong with my truck. The fuel pump relay and the fuel pump. There are some small things still not quite right.
If the pump is not turning on at all, the first thing I'd do is test to see if there is voltage getting the pump. If not, then look into fuses and the relay. If there IS around 12 volts getting to the pump then it's bad. I'm not sure where the relay is on your truck but start by checking the ECM-B fuse, I think that got another member's truck going.

I think, if you dont have much mechanical knowledge or background, you should take it to a pro, or someone who works on vehicles more often than yourself. Im not bashing you, don't get me wrong, vehicles these days are complicated.

DOG Kicks Ass! "Yea Brah" how do ya spell that anyways? we say bro, you say "brah"

the relays on my truck is located in the glove box compartment.. but my question is.. how do you know if the relay is bad..? is there like a clicking sound when you turn the key over..?

[spideyjected]

They can be tested to a point. However you can hear a clicking sound and the relay still be bad from corrosion inside. I know on my truck "which is a 1993" you can use a small section of wire to bypass the relay for the purposes of testing the circut. I'm not certain if it is the same for the newer trucks though. Relays are fairly cheap, maybe you just want to pick one up to try. Also, did you check every fuse yet?

[s-10 2.2much]

you could cross the relay with a wire and see if the fuel pump turns on ? the relay acts as a switch so if you can by pass it with a small wire ive done it to mine but cannot remeber what 2 spots to cross ? sorry for my crappy explantation

[s-10 2.2much]

shoot i was to late sorry for the same awnser as above !

[12sws27]

A Haynes or Chilton repair manual would help you out a great deal with fixing your problem and learning many things about your truck. I used to keep mine in the bathroom. I would open it up and start reading while sitting on the can :D

You should be able to get one from any of your local auto parts stores for less than $20. That is unless prices in Hawaii or different.

Hope you figure out your problem and get it fixed quickly. Good luck.

[csl2006]

what my buddy has told me about relays and testing them something to do with a 9v battery and something another I dunno =/ he lost me at 9v. x2 eric. check voltage goin to your fuel pump. If its not the sending unit, the filter on the pump could of got a tear or just wore out and collapsed causing suction problems (had it happen on my 91 2.5) what year is your truck?

[Big Mack Daddy]

its a 97 cody

[csl2006]

ah must of misssed that thanks. Well at least its somewhat pinpointed. Ignition source, relay, bad pump or sending unit. Test em all.

checked and changed some fuses allready.. i think i should pick up couple relays allready just to make sure that all my relays are in working condition.. couldn't understand why my "NEW" fuel pump is not turning on.. men im getting>>:mad: allready!! haha..

so did your truck's fuel pump turned on and run when you crossed the relay with a wire..? but i kinda scared in doing that.. cuz i don't have enough experience dealing with electricals and fuel stuff in a vehicle yet!!:)

[csl2006]

^nothing should happen (blow up catch fire etc) most that could happen is you getting electrocuted :P

haha.. lol i get one of those long time ago.. but couldn't find um... hesitating in picking up one other one cuz i might just find um later on.. but that could be really helpful right now though!! i'll let you know the progress...:D

one thing i know for sure is that it's not my fuel pump!! cuz i just had drop a brand new one 3days ago..

where is the sending unit located..?

and my truck year is 97

[tomaitz]

^nothing should happen (blow up catch fire etc) most that could happen is you getting electrocuted :P

hopefully!! haha...well.. wat else you think i should do..?

[tomaitz]

anyone..?????


where can i found the fuel sending unit..?:confused:

[csl2006]

what brand of fuel pump you put in it? been a few on here experience bad/faulty fuel pumps

[tomaitz]

i foreget the brand name.. but i got from napa!!

[spideyjected]

The sending unit is part of the pump. The NAPA pump is an Airtex, they are crap. It has a year warranty. Id pull the pump, then you'll be able to see if the volts are getting back there. The ONLY way to go for fuel pumps is the OE AC/ Delco OR Bosch

[BigTruckDrivah]

Your so helpful Eric.

[spideyjected]

I try...(o:

I know first hand "as everyone else here does", sometimes it feels like you're beating a dead horse:mad:

sh*t!! i should have research more about this thing.. the thing is so expensive too.. and no return once you drop it in allready!!

well.. im gonna work on the truck today!! i let you guyz know what is the latest.. today i will try grab some relays for my truck.. to see if my fuel pump turns on....

btw.. does anybody here get one ecu unit for my truck.. i think that could be the one too.. wat do you guyz think...??

[spideyjected]

I'd think the ECM is the least likely suspect honestly.

[tomaitz]

worked on the truck today........

and so far..... still no luck!!:mad:

and i checked the brand of th fuel pump i went put in.. that is from napa!! negative it's not airtex brand!!! it's called something else... i forget allready!! my bad.. had a long day that's why!!

i even had borrow one OBD2 scanner from a friend of mine.. for my truck.. but everytime.. that thing says "ERROR" there is no codes comming out!!

still there is no voltage going to my fuel pump!! i know that for sure..

tom. i will try change all my relays.. on my truck.. i only have three relays on my glove box compartment.. and i don't know which one is the one for the fuel pump.. i no like keep guessing so im just gonna change them all...

any idea what i should go check next..?

[trusconi]

check the ground wire to the fuel pump i replaced a fuel pump on a 2000 only to find it was a bad ground.

[spideyjected]

I'm curious why the scanner couldn't read the computer. I know very little about the computers.

[tomaitz]

check the ground wire to the fuel pump i replaced a fuel pump on a 2000 only to find it was a bad ground.

TODAY = NO LUCK AGAIN!!

there is no codes comming out of the scanner and it says that there is no stored codes in my truck's computer!! so i know my ecu in working condition..

tom. i will try put back my old fuel pump see if the thing works with all the new relays including the fuel pump relay that i just went drop in today!!

but i would definitely look on that one tom. if i get enough time.. see if my grounds is good!!

and i think i would say my last resort goin be is.. i will just make a toggle swith to my fuel tank so it turns on.. cuz till now still it's not turning on...:(

[tomaitz]

i dont know.. that's all i say right now!!

[jacobg128]

Right now, I am facing kind of the same problem with mine, although you apparently have a little more time to work on yours than I do. Just a thought, but you should definately either find your manual, or buy a new one. Use that and a test light and follow the circut from from the switch to the relay and on out. My friend had a 98 that he replaced two pumps in and it came down to a loose connection. Good luck.

like i said bad Ground?

[tomaitz]

is that the ground that is connected to the tank you guyz stay talking about..? or the one that is connected to the relay..?

[spideyjected]

Most likely it's the one by the tank. Mine attached to a frame cross member, but again, my truck is a 93.

[offroadfirstgen]

did u check the fuzes? i had a no start the ecu fuze blew might cause an error code to showup.. does the check engine light come on when u turn the key on? it is supposed to.

[Bozup]

you need fuel, fire, and air.... i would spray carb cleaner and if starts and runs for a few seconds then you know fuel. if it still just turns over and no actually run time then you know electrical

[tomaitz]

mines one too is connected to the frame!! i think there is a possibility that it's just the ground... its giving me a lil more hope..

[tomaitz]

did u check the fuzes? i had a no start the ecu fuze blew might cause an error code to showup.. does the check engine light come on when u turn the key on? it is supposed to.

yup checked all the fuses everything is good even changed the relays.. its just that my fuel pump is not turning on...:mad:

[tomaitz]

you need fuel, fire, and air.... i would spray carb cleaner and if starts and runs for a few seconds then you know fuel. if it still just turns over and no actually run time then you know electrical

done that allready.. sprayed a carb cleaner and it starts and runs fine for almost a minute.. used the whole can!! and after that the truck just turns over again and no run time like you said... so i think i will agree with you!! it's something electrical problems.. cuz i know my fuel pump is not turning on..

im going to work on the truck again this weekend on my days off from work.. i'll keep you guyz posted..:D
