This on my 02 2.6 puller
After new pistons , billet main caps and block fill the truck hasn't ran rite. It cuts out at about the 2000 to 2300 rpm range. It doesn't do it all the time. Hit or miss. The reluctor wheel seems tight through the crank sensor hole. Aready replaced filters 3 times. Carries fuel rail pressure. Ran new grounds to the block and frame. Went over the engine harness didn't see anything wrong. (Not saying it's not the problem ) battery is good. Just took valve covers back off to make sure I didn't screw putting wires on injectors. They were fine. Truck ran when I parked it in the fall. No rats nest under the fuse block
Again the truck will run fine at times them it won't. I'm guessing a short someplace.

I'm pulling what hair I have left out.
Thanks in advance
Mike
Ps. No codes either
