Engine Mechanical problem
1992 GMC C2500 V8 Four Wheel Drive Automatic 250000 miles
I started my ruck and went a block away and it just shut off. The service engine light is on ad it won't start. I addedgas to it and a new fuel filte and it didn't help. My brother found out that iis not thefuel pump because it is pumping to the filter. I changed the injector wires an it didn't help. I need to know what I should try next. I have TBI injection with two injectors and a carburator. Please let me know what to do next.
