Starts but dies, my truck is making me criminally insane
 

I have checked my fuel pressure. I have checked my pump and sending unit. I have checked the circuit to the pump and sending unit. I have replaced every relay and fuse associated with the fuel and ignition system. I have replaced every sensor and switch associated with the fuel and ignition system.Is there something I'm missing that could lead the truck to start, idle quite high for 3-4 seconds, then begin to slow down so much in idle speed that it starts shuddering until it utterly dies? I'm starting to think this truck cannot be fixed.

Ballast resistor, driver side inner fender, near air box. Has 2 wires connected to it. It is common for these to fail. To confirm, pull the 2 wires and jump them together and attempt to start/run vehicle. If this works, more permanently jumper the wires and voila!

I have no current going to the ballast resistor even when key is in start or run. I think that's where I need to start looking for my problem

Fletch why are you digging up all the old posts under MJ tech? What's your angle man
