Re: 92 Gmc Jimmy 4.3 Ltr Cfi Problems!?!
when you are having this trouble and it just cranks do you know if it is getting only spark or only fuel? that would be the first thing to check to diagnose your problem. my initial guess is its going to be wiring trouble.
i had a 91 sonoma that would do that but it always blew a fuse when it did die. the wire caseing behind the motor had fell apart and one of the wires was grounding on the engine or bell houseing. it would blow the ecm fuse incase yours is doing the same.
any way enough rambleing on next time yours dose it try and check your basics seeif there is fire and fuel and that would be a good start to getting your problem solved.
keep us informed
Bud.
