93 grand am won't start

93 grand am 3.3L ran 2 days ago. Will not start turns over. Will run by squirting gas in the intake. Fuel pump works and has pressure. help????

Did you test for spark?

Have you ever replaced the fuel filter?
What was the PSI on the fuel pressure?

it has spark will run if gas is squirted into intake, cannot check for codes no service engine soon light???? do not get anything if i use a jumper wire to try to get codes fuel pump does not run when key is turned on but will run if you crank the engine for 5 seconds then it will run for 15. have swapped computer but that didnt help.

I'd try changing the fuel filter.

And check the fuel pump relay, its either that or your fuel pump is going out.

where is the fuel pump relay located??? i cant find anywhere that shows me

pretty sure its under the hood, pass side. If not there then on the firewall. big 1" square looking things.

Should be 4 of them that look simular.
Cant say for certain which ones are which because they get moved around.
Though I believe thiers one pair is the fuel pump and the other one is for the AC.
They have markings on the side to match the 2 pairs.
The ones for the FP and AC can be interchanged to see if this is your problem, that is .... as long as the AC relay is good.

Hope that helps.

ok it isnt the relay...why would i not get a service engine soon light or be able to pull the codes?

Sounds more to me like your system as a short. You engine is running in the open loop for the first 15 secs then when the loop closed your motor stops. Pretty normal. Let a shop trouble shoot. Could be as easy as an injector with a short but you wont know if you dont have the tools. I say this from exp..

If the light bulb was blown you wont get a service light.
On pulling codes its hard to say, not all codes are visible with the obd and a paper clip.

Might get some codes with a scan tool. :dunno:

If the relay was good then its possible your fuel pump is dying. Or a fuse for the fuel pump or the injectors fuse could also be blown.

Good Luck

ok looking for help here still.....i got the fuel pump problems solved but now I have no spark and no injectors......have had the ignition module tested and its ok replaced the crankshaft position sensor..any ideas????

have the coils tested. And I'd check the wiring for any shorts/breaks in the ignition system.

COuld have a bad ECU :dunno:
