Bringing non-runner M1165A1 REV back to life!

[Mogman]

During the takedown process of removing the power steering reservoir, intake manifold, turbo crossover, etc I noticed some damage to the engine harness, including the main ground wire (3C) as well as the three wires to the TPS (Throttle Positioning Sensor). The TPS wires were severed completely. Would a disconnected TPS cause the rough idling in the video I posted above? Wondering if that's been my culprit all along...

Not likely, there is nothing electric about the engine but for the shut down solenoid.

Welp.... found the problem: https://youtube.com/shorts/oQPNdCx3f98?feature=share

Don't think there's a fuel additive that can fix this issue.

unfortunately that is all to common

That’s what I’m hearing… Recommend any IP rebuilders that I can send this to?

DIY on the pump rebuild. ( youtube university if needed) Might get luck by just taking the bottom end off and cleaning it up.

Would love to, but I hear special tools are needed for calibrating it. But yes, if rebuilding the bottom end fixes it, that would be great! Turns out this is not a Stanadyne IP, but is an AMBAC Model AB5079R. Know where I can find the rebuild kit for it? At least for the bottom end (replacement plunger shaft, etc).

Try DCP 901-343-6453, but I would cover the inlet and outlets and wire brush or soda blast the case...get it clean... then take the 2 side caps off, then the bottom bolt, see if you can clean what you have up or if its needs replacement parts.

DO NOT USE DCP….worst pump rebuilder in the U.S.
just buy a new or rebuilt from HPG or MAC

DCP sells parts …your pump works, but you light load advance is stuck. Could be a simple fix.
