Hypertech and bullydog. Havent messed with either in 4-5 months. Has a raptor fuel pump on it, relay went out. Replaced it now it wont shut off. i know the pumps not running. With the key off truck will run. Pull battery cables connect again most dash warning lights are on without key on.

 

Sound like a failed ignition switch.

Im not sure everything else with the switch seems to work good. Just wondered if people had ideas.

 

Just sounds like an ignition switch. If i get a second tomorrow ill look up and get you a way to confirm it via wiring.

I left the truck run with the key out. Ran for about 5 minutes and died. I left it alone a few minutes later the headlights flashed on and off a few times?

 

Check all your grounds! The CP3 will pull fuel even with the pump off! Till it creates a vacuum to strong to overcome!

 

Injectors wont fire without current regardless of fuel pressure unless a nozzle is cracked. He would first complain of smoke, misfire,low power and oil dilution if this was the case.

Left batteries unplugged overnight. Shuts off fine today probly a dozen times. However the headlights come on when they want as the trucks off?
