7.3 Powerstroke Shop

I am looking for a honest, good shop to take my truck to. I have two major issues.
Blowing fuse 24 underneath the hood, with new diesel pump.

Long Crank issue take two good long cranks, then engine surge on start up (could this be a short?) no clue. I and a Ford scan tool and a AE on my laptop. Just lacking the knowledge to where to start.
I have noticed oil in valley but no drip? replaced ICP, IPR, HPOP, new injectors, Turbo,

I have a with good oil drip

Currently at my uncles bodyshop. If you know a guy please let me know.

thanks

Fuse 24 is PCM power. Not sure if it's before or after the relay but either way it's a short run and finding the short causing the fuse to pop shouldn't be to bad.

Fuel bowl heating element and PCM is fuse #30, which is also a 30 amp

I had a look at the colored wiring diagram from the tech section and it shows pins 71 and 91 of the PCM connector are the power inputs and they are both fed from, it's says fuse 22, but since the 02 fuse panel is different I can't say for certain that it would match to your 01. The 85 pin of the relay connects to the PCM diode and the 86 pin to the ignition switch.

If the truck is currently at a body shop, review every inch of the way, the work that you had done there. Did they pull a front fender? Pinched wires anywhere?
