It won't start. It turns over and acts like it's going to start but don't. I thought it was a problem with the security system but I've done all the bypass tricks that normally work but it won't work. I've changed all the spark plugs and fuses and the battery. Also changed the fuel pump. I've checked all fluids plus the fuel pump and starter and both kick on just fine. The security light stays on flashing and the battery dies extremely fast. Anyone know what the issue could be and what I can do to fix it? My truck is the newer body.

Fuel injector harness ohms good back to the harness for fuse block. Replaced spark plug, spark plug wire and fuel injector. Any help is greatly appreciated. Does anyone have a wire diagram for cylinder 5 fuel injector? Runs on 7 cylinders not 3 as they say. Haha

I’ve been working on this truck for a while now and I’ve managed to fix all problems that my check engine light reports. There is no longer any check engine lights but I’m still experiencing some problems. When ever I’m in a parking lot about to reverse park, my truck will suddenly cut its self off. I am also experiencing some poor engine responses as well as delayed acceleration. I’ve replaced spark plugs/wires, all O2sensors, EGR value, air filter, and gas filter also have done a gas treatment.
