What is the battery when your trying to crank the engine?

 

Brand? Motomaster 850 CCA.

The truck was running prior to replacing the slave. The other battery wasnt holding a charge and buldged.

 

Unless you have a multimeter I can't and won't try to help. It's one of the most basic tools for electrical diagnosis.

 

I do have a meter, not the best with it as I hate electrical.

 

Can you list the other "installations" that were done at the same time?

"There were other installations done but have nothing to do with the drive train."

 

Exhaust down pipe (new upstream and downstream O2 sensors), cat, cat back exhaust (OEM), rear drums, lines, shoes and pistons, front to back line to the proprotion valve on the resr diff.

 

Follow the large grounding wire from the negative battery post to the? Does the wire connect to the truck FRAME anywhere? Does the wire go directly to the starter bolt? Does the wire go to the truck frame and then the starter bolt? Does the ground wire split off and connect a smaller wire to the inner front fender of the truck?

If you could post some photos of your truck's engine compartment, particularly of the positive and negative battery wiring......that may help us see what you are dealing with.

 

Engine ground. Removed and cleaned at both ends.

New relay.

Start ground. Cleaned

Constant and ignition. Cleaned, both have 12v or higher.

 

Try turning the engine over with a socket on the front pulley. If it won't turn maybe there's a mechanical problem.

 

I was thinking that, thanks. I rolled it back today in gear. The annoying part is that fact it drove into the garage under its own power. Heck, I drove it onto the damn trailer haha.
