1989 Chevy Truck 6 cyl Four Wheel Drive Manual

I was driving my truck and it was running great then all of a sudden it died, It has fuel pressure and I can put gas in the throttle body and it starts, I changed the fuel pump, distributor and checked all the fuses in the fuse box on the left side if the steering wheel. I can ground one pin on the injector and power the other and the injector spits fuel.

Please help me I am very willing to pay

Check the fuel pressure with a fuel pressure gauge designed for your fuel system if okay If cranking over and injector has power on one side and not pulsing check the computer ground drivers.

Why are you this? You can put gas in it and will start-you have replace the distributor-why what's missing here fuel or spark

I replaced the distributer because I was told the pick up coil drives the injectors, I put power to the injector to insure the injector was good, the ground on the injector is not pulsing
