I have a 1999 Jimmy and have taken good care of it. 137,000. Miles. It cut off while driving, no fuel pressure so I replaced the fuel pump, fuel line (cracked & leaking) and fuel filter. Had 50ilb of pressure started fine for about 1 month and then would not crank again. Replaced injector spider, cranked for about 1 week and then would not crank again. Replaced Crank shaft module and camshaft module. Cranked for 1 - 2 weeks and now cranks sometmes and other times it won't crank. Please help!

Could be a bad starter/solenoid. Check for 12 volts at the small wire on the starter with key in crank position. If it has power then the starter needs to be replaced. If none, then get back to me and we will figure out where it stops.

I don't think it's the starter, it turns over fne it's appears not to be getting any fuel. Do I still need to check the starter if it is turning over O.K? I did some research last night and I think it may be the Body Control Module, Is there a way to check this to see if it's working properly?

Thanks!

Does it crank and not start? Or does it not crank?

Not Cranking Over
When your engine is not cranking (turning) over it will be mainly due to three separate areas, first it could be the battery, cables or poor connection, next is the starter...
