Let my start from the beginning!, I got it from my buddy, it has been sitting a while. A couple of years. Long bed, with a 6.5 turbo 4x4! I would say a 9 out of 10! From the factory 1/2 ton don;'t ask me why? Cause i;'m shock also! Fuel assumption? Anyway , i need someone with a computer that can diagnose precisely! I have changed the pmd, its getting fuel at the T, i did the paper clip reading said glow plug relay circuit. Forget the code! I actually installed a ford solenoid to bypass the glow plug relay! I have replaced the oil sending unit, the fuel shut off switch, all of the relays and fuses, and pretty sure ive gone thru every ground wire! I am trying so hard to get this truck going for a reason! I am not proud of it but , i lost my drivers license 20 plus years ago! I can get them back in 2 weeks, obviously learned my lesson. Someone please help me please figure this Chevy out! Thank You, and god bless!
