Just wondering what makes you think its only running on four cyl's? If it is have you tested the wiring harness, and checked if you have a signal to all injectors/ plugs?

The GPs "seem" to be good? How'd you test them? Ohm them out through the UVCHs?
Did you check all the connections on the UVCHs and the wires for chaffing?
Because you need the block heater, and the truck runs bad, probably the connections or wires/harness are bad. They provide power to the GPs and injectors.

i got pwr to glow plugs when i turn the key as it should and replaced 1 bad glow plug that was ohmed open . How do you check power to the injectors ?? please explain should i start motor and unplug each valve cvr plug at a time while running ?? check for pwr at the plug .. there are three wires that feed two injectors on each pug . i assume one is a ground ?? what should i read and on which plug terminals ?

also i dont know how many cylinders are not firing exactly ...i was told i need to recheck how injectors are seated and o rings ...maybe an injecter is stuck open ?? thus dumping fuel into the motor thus dumping raw fuel into the exhaust

New wiring means the wires are good. Doesn't mean it was connected well. Until it's checked for sure, it can't be ruled out.

a buzz test should tell you if injectors are electrically functioning, only issue is i have been looking for a way to do it on the earlier motors and cant seem to find one. (myself anyways). Could be a stuck injector i supposed, the only time i've seen that is on a 6l and it billowed black smoke. Think mine are fouled and they are stinky white until it warms up. Could it possibly be something silly like low oil level or fuel filter?
