I clicked the key and read codes for lift pump, injector pump,over boost,and ecm. ihave quadzilla 120hp module and its unplugged. i hauled a car with truck yesterday and it drove fine on 30hp setting. please help!!!

The number of faults would lead me to suspect a bad connection to the ECM or the Quadzilla was the problem, but it could be that the modules were unplugged with the batteries still connected, and that can blow one or both ECM and PCM.

I would disconnect the battery grounds, turn on the ignition key and lights, and let it set long enough to drain all the capacitors in the truck. Check your connections, and make sure they are dry and coated with dielectric grease.

Then turn off the lights and key, and double check the connection to the camshaft sensor, then reconnect the batteries and cycle the key twice, then start it.
