Need diagram (and a shot of Jäger)

02 E450 need ckp wiring diagram

Stalling when hot, only fault is crank code

My issue is this was an ambulance, but is now a flatbed, and also had the worst shop in existence just "check" the ECM leaving shredded and ripped wires everywhere.

Check out all these probe holes haha

ambulance?
looks more like former U-haul colors.

I think I'd just replace the engine harness. Lol
It's a good possibility that the wires to the CPS are corroded from the pokes and opening up when warm.

Was definitely ambulance. Has "medic" still faded on hood as well as holes all over it for lights.
It also has those hydraulic snow chains.

I'm confused why someone at some point hacked off the body and put a flatbed on it (it is a lift bed)

But when it was converted from.ambulance most of the ambulance wires were just chopped, but still all in the harnesses.

The flatbed and additional things this owner has installed has added even more rats nest. It makes me want to cry every time I have to work on it.

The rear AC lines are spliced together with rubber hose (somehow doesn't leak yet!).

The rear heat lines are just bent like accordians.

But after checking fuel pressure while it sputtered, I'm suspecting IPR?

Hard to work on it as it cannot be left here. Owner lives in PA and uses it as a work truck.

IPR is unrelated to fuel pressure as it controls the high pressure oil to the injectors.

What was the fuel pressure reading? Anything below 65psi isn't good.

There are in-tank screens that get clogged and block the fuel flow to the pump on the rail.

There is also the regulator at the fuel bowl that can wear and need to be rebuilt, although this would cause low pressure all of the time.

Those things are awesome!
Expensive.... But awesome!
