I have an 89 gta with 77,000 miles its always ran like a champ until a couple months ago. While returning home from a weekend trip about fifteen minutes outside of town the car suddenly lost all power rpms dropped and it died it would only crank over but not fire i towed it into a shop after playing around with it for a while they said i had 3 bad fuel injectors and a bad computer not having much cash they said if i replaced the computer i could probably make it home at least (2hour drive) so thats what we did i got out in the country 15 mins away and bam it fell on its face again but did restart only to die 45 seconds later then would only crank but not fire up so we towed it again replaced the faulty injectors and i made it home fine and drove for a couple weeks trouble free then when leaving town again i got about an hour away and the check engine light came on all gauges read fine i pulled over checked fluides all seemed ok i started the car and turned around and went home issue free it ran fine no check engine light i checked the code and it said low vacume asociated with the egr i forgot the code # but i drove for a couple more weeks trouble free then yesterday after racing(and winning) i was driving around town and stopped at a stoplight i glanced at my gauges and my oil pressure was allthe way down!!!!! as soon as i noticed the car shut off no smoke no funny noise just died it still cranks but wont fire over the oil pressure builds when cranking so im a little confused it doesnt leak any oil or sound as if the engine is mechanically damaged i didnt check fuel pressure yet but when i pressed the valve on the rail fuel sprayed out any suggestions would be helpfull i need to get her back on the road.

 

I played with it a little more last night it is getting spark and it is getting fuel to the rail but when you turn the key forward it has no check engine or other lights besides the seat belt and security which turn off after a few seconds also when you put a jumper in the terminal it doesnt flash the check engine light the light just worked prior to the car dying so im going to assume i may have burnt another computer and there must be some underlying reason it keeps doing this. Any insight would be helpfull.

 

Dan,

I dont have an answer but if none of the lights are coming on with the key in run position, i would be checking fuses, sadly the only way i know to check your computer is with a scanner, and even at that you dont really check the computer, just everything else. (process of elimination) for if everything going into the computer is fine then computer is suspect. I would also peek around at your ground connections everywhere you can find them, a loose ground behind/under the dash can wreak havoc on gauges and computer equip. I wish i could be of more help.
