Can we assume correctly that by ‘just plugged it in to see if it ran’ you mean you had the new PMD mounted on to a heat sink the whole time you were testing it to see if it ran? Just making sure.
Confirm the advice on fuel pressure at the Fuel Filter manager. A quick and dirty way is to use an inexpensive pressure/ vacuum gauge. Replace the hose with a long enough length of 1/4” line to run from the T-Valve and up to the windshield. Tape the gauge securely to the windshield so you can...
Auto Spell Correct correction: The tires from S. Korea are NEXENs, Not “Nextel.” Auto Correct; Just one more of the technologies making my life less enjoyable….
Thought about Injectors too so, I have a new set that I want to get tested before swapping in.
The current set of Duraturm’s have...
Notice while up in MT last summer trying to be of help to Big-T that my first starts were starting to have a little smoke. Hmmm Acrid diesel smoke that cleared up quickly as engine came to life.
It was kinda hit and miss up there but, when it ‘hit’, the smokewas getting a little worse. Longer...
Correct. GM designed the fuel system so the tank maintains a low pressure state. The low pressure is created by the LP pulling fuel and then pushing it to the injection pump. That low pressure assists in pulling the return fuel back to the tank.
FWIW, I recently learned that the IP’s internal...
You might want to check the windshield seal for signs of deformity, age etc. causing leakage around the sides and bottom. Difficult to ascertain but, its possible. Leaks at the tops running inside would be visible inside the glass (current issue of my own).
The further up the firewall the...
Confirm all the grounds are attached at the back of the lower intake manifold, passenger side. Two of them (one brown and white, the other black) provide the grounds for the ECM. No grounds, no ECM commands to tell the PMD what to do.
FWIW PMD heat sink attached to the upper intake is only...
Finally got around to replacing the driver’s side hinge pins. Door was sagging and very difficult to close. It required so much force to slam it shut the door panel would stay attached.
Only challenge was securing/suspending the door after pulling the old ones. I rigged a 2x4 through the open...
Given that random stalling / cruise control loss are symptomatic of a PMD issue and that you have a couple of PMDs (if I read earlier posts correctly) that I’m sure you’ve tried already, I’d be looking at checking the condition of the PMD harness since you’ve got your file set out and cleaning...
ECM Pin Out Schematics 1997. Have to break them down into parts as a single file is too large.
FWIW, The files say PCM but, we know it as "ECM" semantics, schmantics, Schematics....
Yeah, pan is close to the HB but, the bolts go in different from what I recalled in my morning fog. Was about to post that. While trying to find a picture of the studs I did discover why a shouldn’t post so soon after waking up having finally slept in past 3:30… I ‘remembered wrong’ the angles...
You could try studs and nuts. Can’t remember the length and size (M6?) since they have worked well on mine for the past 11 years. Just had to insert the studs at the front after you’ve laid the pan down as the angle makes laying the pan on evenly a non-starter otherwise. Could always use the...
