SOURCE: 2000 GMC Jimmy will not start
The oil presure switch does have some bearing on the problem but my suggestion is to change the coil. I had a the same problem with an astro van. I changed everything that you have described and it fixed the problem just for a little while and then all of a sudden did it again. I changed the coild and the cold start swithch and never had the problem again.
SOURCE: ECM BATT fuse keeps blowing
That fuse provides power for the fuel pump. Either your fuel pump is blowing the fuse or there is a shorted wire.
SOURCE: truck wont start keeps blowing the ecm batt fuse
You have a short (bear wire) somewhere. Trace the wire and find it.
Have a great evening

haveing the same problem 1997 jimmy doing the same exact thing i got wire digrams for it still no luck so if anyone know whats causeing please help
SOURCE: I have a1994 gmc Sonoma. Fuel pump fuse keeps
The only other things on that circuit are your PCM(power control module) and the fuel pump/oil pressure switch. You can start with that but it is more than likely a ground somewhere on that circuit. If this helped four thumbs up please.
