1998 Other Chevrolet Models V8 Four Wheel Drive Automatic 105000 miles
I have a chevrolet K1500 4 wheel drive pick-up with a 5.7 engine. Once in a while when I took the truck for a ride, when I returned back home in a while I would try to start the truck again but it would just turn over but not start. This started happening more often until now the truck won't start at all. I changed the fuel pressure switch, the fuel pump relay and the complete full pump assy. Even though I was getting spark I changed the cap and rotor anyway, I also checked the crank pos. Sencer and it was ok. When I put gas into the throttle body the truck will run until the gas runs out of the throttle body. I have also changed the fuel filter. I don't know where to go from here.
First of all thank you so much for your donation. Is there anyway you could rent a code reader and see if you have any code's?Also have you checked your fuel pressure yet or have you checked to see if your injector's are pulsing?

Hi Louie, My codes are clear and the fuel pump is putting out 64 psi. I would have to take off the top intake manfold to get at the fuel injectors. This truck has Central Sequential Fuel Injection ( Central SFI System ). Is it possible that the injectors are not getting the gas to them?

The wiring diagrams that you e-mailed were were blurry and could not read them even at the small print. Would it be possible to send them at a larger format.
