Question about 1993 GMC Jimmy
The computer controls the fuel injectors.they should measue about 1.4 ohms each.
put fuel directly into the throttle body and see if it will start.
check the wiring to the safety netral switch and all the grounds.
make sure that the ecu is seeing an input from the ignition switch.otherwise it will not turn on the pump.it is a complex setup and you need a wiring diagram
