Okay need some help here if possible, let me start from beginning, truck died one day on the way home and found driverside fuel pump was bad, I replaced it and truck ran great for 2 days then died again. I checked pump and it was getting 8 volts at the plug, figuring that fuel selector was bad replaced it, and fuel filter and nothing, would turn over but no fuel, so after reading things through out the internet I replaced fuel selector switch, ignition module, fuel pump relay, injectors, iac valve, ignition switch and battery cables. After disconnecting battery and reconnecting it will no longer even turn over, tried 2 different batteries and nothing, checked voltage on both sides of fuseable link and getting 13 volts both sides. I have even changed oil pressure switch. What am I missing, I can here relay energize, but when I check for voltage out of fire wall to plug that runs to pump nothing, hooked up to scanners and it is communicating with ecm and no codes, this truck only has 120,000 miles on it, and is in great shape other than my existing problem, any help might save me from losing my mind!!
