THE TRUCK WONT START. REPLACED MAIN RELAY FOR FUEL PUMP AND INJECTORS. TESTED ALL ELECTRICAL INCLUDING OHM READINGS FOR INJECTORS, COIL, MAIN OPEN RELAY, AND SO ON. CHECKED FUEL PUMP FOR OPERATION AND PRESSURE. THATS GOOD. IT WILL START AND RUN OFF OF ETHOR BUT IT SEEMS THAT MY INJECTORS ARENT OPENING. THE ONLY THING I CAN THINK OF IS THE COMPUTER. SOMEONE HAD MENTIONED POSSIBLY MY DISTRIBUTOR? DOES THAT SEND A SIGNAL TO THE INJECTORS WHEN TO OPEN? SOMEONE PLEASE HELP!

Could be an open wire between the ignition switch and solenoid resistor, the solenoid resistor itself or the grounding circuit of circuit 10/20 drivers on the computer
