Does anyone know what the fuel presure should be?? and am i guessing right??
Pumping a fuel injected vehice should have no effect. Check teh voltage the the injectors. Use the injector ground to the injector + it should show a good strong pulse. If the 12 volts is solid and the pulse doesnt look good, the ground is bad. This is common on these trucks. It is the ground for the computer theat the injector groung pulls up to. If you can get a schematic, it should be easy to find. Check the Autozone site, that have a lot of schematics for that vintage vehicle.
