Ground cable next to ECM

Where does this flat black ground cable connect to. I can not remember for the life of me. I think it's what's causing the truck not to turn over.

If your asking where on the motor it connects to there is a stud right between the GPM and down pipe. It stud holds the heat shield down for the HPFP.

That's the answer I was looking for. Although it didn't fix my problem. Turn the the key and still no crank

did you reconnect the actual starter wire behind passenger side battery? if so, disconnect it and jump 12v to the starter side, see if it spins over, if it does than everything starter side is good, you have a communication issue further up the line

It's not the starter Checked that. Gotta be comm issue. I did just realize the keyless won't work

just recheck all the main harness pugs by driver side fender well, alot of the time those connectors are hard to lock back into place. also make sure the power wire is connected to left side battery.

I rechecked all plugs. Nothing on driver fender was disconnected. Pulled engine harness with motor cab on All cables are attached at the battery's Fuel pump is a A1000. It doesn't seem to be coming on either

I think the fuel pump is your problem. It needs to be wired into the main harness. You should be able to pull a code. At least my truck did this after putting on an airdog and not using the factory harness
