Brand new to this forum and hoping for help
I own a 1992 C4 with an LT1 engine. It has been driving me crazy (if it drives at all). I have been through it with a fine tooth comb and the problem I am having is electrical.
So I came here hoping to find someone who knows how to help me. I saw an old post by grumpvette and it seems like he knows a lot, but not even sure how to properly ask my questions.
So, who is the most knowledgeable person that posts here especially on my model? I would like to ask my question in the right place but don't know where (or who to ask) Please help. I'm desperate.
THANKS TO ALL!



a couple scanner related tools worth owning
owning a decent code scanner helps
down load and print the instruction manual

as always you should start with basics like posting..
what year car? (1992 I see)
whats the issues your having?
do you own a decent code reader(it helps)
details matter
what parts have you tested or replaced?
what tools do you have?
do you own a factory shop manual for your year car?(it helps)
IF NOT WHY NOT??
there's nothing on a c4 corvette ,you can't fix if you have basic skills ,
and a few required tools and reasonably deep financial pockets, (parts can get expensive and a few hard to locate)

learn to use the factory shop manual, and a multi meter and LISTEN to the engine closely

EFI works at higher pressures (a 1985-1991 TPI corvette as an example generally operates in the 38psi-42 psi fuel pressure range)
THINK,

fuel tank...to .fuel filter....to .-fuel pump....to feed into fuel rail& injectors. then out too....fuel pressure regulator...then too..return line to fuel tank
