....and maybe check the lift pump in the tank.

Yes - get a gauge for fuel pressure between the filter housing and the injection pump, if you can.

When I bought my 24v, someone had “updated” from the block mounted lift pump, to the in-tank pump. Problem was, they never removed the block pump, and were pushing fuel through it! I only had around 4psi into the injection pump! I resolved it by removing and eliminating the tank pump, and installing a FASS DRP on the block. For the last 4 years it runs between 14-18psi consistently.

Not on a 94 12 valve

alright, so I took a look at it, and he had another shop lower the idle because he though it was too jerky when put in gear from idle, idle speed was at 600 in park, and setteled at about 475 in gear with the A/C on, i told him that is way to low and hes lucky it could still pump oil through the bearings, i adjusted the idle and got it at 750 in gear with it dropping to around 710 when the A/C engages.

i know that still low by the book, but he was hell bent on it being as low as possible, hes a retired truck driver and thinks 500 should be what every diesel idles at, I told him this is far from a 3406 or isx15.

hopefully it doesnt need anymore work, cause honestly I dont like arguing with people in order to set something to factory spec.

Isn’t 900 rpm spec?

I found 750-800 in gear with A/C on.
