Ok, so this is my first post here, and forgive me for any ignorance i show, as i know next to nothing about pushrod style engines, or v6's at all for that matter (i drive a subaru...)
anyway, my girlfriend's car is dead. Its a 1995 Chevy Lumina with the 3100 (L82) SFI engine. She was driving down the road and suddenly the engine just stalled. had to tow it back home, and it hasnt started on its own since.
at first i thought it was the ignition control module (ICM), but all coils are sparking, so it isnt that. Then we sprayed carb cleaner in the intake hose an the engine started and ran as long as we were spraying (albeit very roughly).
now im thinking it must be fuel system related... what pressure should the fuel be at the rail for this engine? i hooked up a pressure tester an it read a little over 40psi. if this is healthy, im out of ideas... could all the injectors go bad simultaneously? could it be a fuel pressure regulator? or is it the fuel pump?
any help is appreciated! thanks
