No It Would Have To Be The Whole Connection On One Side Or The Other. If One Connection Is Loose You Dont Have Anything On That Side. It Wont Fire With Only One Bank Connected.

This truck should have two connectors on each bank so it should start if one connector is undone

Fuse for IDM is good, still no tailpipe smoke, so the fuel is not getting through the injectors.

Injector Driver Itself Possibly. Not Very Common But I Have Seen It Once

I am hoping that's not it, I hope it's something simple, but at this point I just want the damn thing fixed and running again.
If it is the IDM how could I make sure it's bad? I don't want to replace parts for the sake of it especially something that's going to cost m over $300

They Arent Very Fun To Get At. Drivers Side Fender Well If I Remeber Correct. Did You Say That You Checked The Crank Sensor? If You Did, Or If You Replaced It, Its Not Out Of The Question That The New Sensor Was Bad Right Out Of The Package. Ive Seen That As Well.

I replaced the CPS, when I crank the engine it registers on the tach. Haven't checked HPOP they guy who had it before stripped the allen plug out so I have to go get a wrench big enough to take the sensor out of the top of it to check it
