1988 olds cutlass supreme FWD 2.8 V6.?

Question

Already changed the fuel filter. the fuel pump comes on. but when the car is started it will run for a couple of seconds then die. i thought about the crank sensor but if it was that then the car wouldnt start at all. at least thats what i think but i could be wrong. can some one please hepl me. what else could be wrong? i dont know if it is a fuel problem or a n electrical problem.

Answer 1

All of the above answers are good, Your car is fuel injected, follow what Ironhand says, and also check your fuel pump relay. You could have a bad crank sensor, or ignition module, but if there are no codes in the computer, I would do a complete check on the fuel system. The ignition switch could also be bad, if it dies as soon as you let off the key.

Answer 2

ELLTEA has a pretty good start to investigate, but a note of experience on these, usually this can be corrected by a VERY GOOD plenum and injector cleaning (if it is fuel injected)
This is not something you are going to have the equipment for. It will need to go to a shop that has a MACHINE that is connected to the fuel rail, and the car is run for a period of time while the machine's chemical detergents "do their thing" with the injectors and the intake plenum. This will also have immeasurable positive effects on the way the car runs and idles, and will PROBABLY increase fuel economy (but no guarantees here).
If your car still happens to be carbureted, Check the choke and fast idle control settings. Adjustment may be necessary.

Good Luck

Answer 3

I havent seen too many FWD vehicles with a 2.8L and carbed, so i will assume it is fuel injected. Had a similar problem with a vehicle like this years ago. Turned out to be the temp sensor. The sensor went bad when the engine was hot. Once the engine cooled, the sensor continued to send a signal that the engine was hot so the ECM leaned out the fuel system in a closed loop. If you have access to a scanner, take the readings on your temp sensor, if the readings say 190 degrees and the engine is cold...........then you found your solution. Bad temp sensor.
good luck.........

Answer 4

have someone run a pressure test on the fuel pump and also it could be the throttle position sensor.i have a 88 olds delta 88 3.8 and it stalls in the morning,and i think its the idle air control sensor,maybe thats your problem.

Answer 5

if the car starts I don't think it is an electrical problem, it sounds like a fuel problem, such as a bad fuel pump.

Answer 6

properly first does it tick whilst it extremely is idling or whilst it extremely is positioned into kit? putting it in force or opposite places a small load on the engine which could make a vulnerable flywheel tick. yet to furnish you some starters examine the A/C compressor, dirt covers, means guidance, smog pump "If equipped" cooling fan(s), and force belt usually worn belts could have small threads start to split from them and hit Shields making a ticking sound. in the experience that your ticking sound would not provide up in any of those places it may maximum in all probability be and inner subject which includes worn crank, rod, or cam bearngs, collapsed lifters, flat spots on cam, worn ballencer shaft "if equipped", worn timing factors gears/chain, worn piston wrist pins, worn or cracked piston skirts or some thing so effortless as a unadjusted rocker arm

Answer 7

have you checked you oil pressure sensor or the o2 sensor?

Answer 8

have same problem with my 2.8 - tps is bad!! replaced it - reset values- all good to go now!!

Answer 9

the '88 is carburated I believe so I'd be looking for a vaccum leak...

Does it run if you keep your foot on the gas?

More information please
