96 olds lss had fuel pump replaced wont stay started long sputter spits ect.


You better find a different mechanic . Before calling a bad fuel pump ,did he do fuel pressure test ? Did he test the electrical circuit ? Did he check mass air flow sensor ,injectors , fuel regulator , engine senors ? How many miles on the vehicle , is the engine in good shape ? Timing chain ?

My car start but won't stay running.


If you replaced the starter & the car starts the starter is good. The reason when it will not stay crank could be multiple things. It could be your fuel pump, dirty fuel filter, bad plugs or wires, etc... See if you are getting fuel to your carburetor or check your fuel pressure. I'm leaning towards the fuel pump . I hope this maybe some help to you.

It starts but will not stay running


If you have already replaced the fuel filter, measure the fuel pressure at the fuel rail. It should be around 35-40 psi when running. If it is not in this range, consider replacing the fuel pressure regulator.

2000 GMC Jimmy, starts up every time, but only runs for 10 seconds then dies. Restarts every time but will not stay running. Replaced fuel pump, fuel filter, CAM position sensor, crank position sensor,...


you say fuel pressure is good, but what is it? what is the fuel pressure when it stalls out? Spec is 60-66 psi and it wont run if its 55 psi. the fuel pump relay should be good if the pump runs. Make sure the ground for the pump is good , G402 should be on left frame rail. you may have had it off to replace the pump? maybe? it may be time to stop guessing and have a repair shop diagnose it for you. You sure have replaced a lot of good parts.

My 95 tahoe starts but dont stay on. Fuel wont stay pumping from tbi. Just swapped a motor from 80's camaro. Was running real good in box chevy perfect. Now fuel wont stay flowing out of injectors. Already...


did you install the oil pressure switch origional to the tahoe? The tahoe uses a low oil pressure shutdown, instead of an inertia switch to shut off the fuel pump in the event of an accident. If the pressure circuit does not close within 3 seconds after the engine starts the fuel pump shuts off. This is in case the truck is on its side or upside down the pump will shut off.

Starts but wont stay running


In reply: if its not the maf there are 2 relays in the relay box i belive its underhood, 1 primes the fuelline to 32psi the second kicks in after it starts, and keeps it running and varies the psi. if the primer relay isnt kicking in then it wont start due to no fuel
