I am new to the forum and am having trouble with the fuel pump on a 1990 chevy 1500; the fuel pump, fuel pump relay have been changed, but when the key is turned on the pump will not get voltage until the key is turned to start and yet the truck still fails to start. I was wonderin if someone had a real good wiring diagram of the fuel system on this truck, also is there a fusible link installed in the system and if so which one is it, the ground for the pump has been cleaned and is showing a good ground, all the trouble started when the truck died goin down the road, the pump has been verified to have been bad but wonder if something else went bad when the pump went bad
