Poor Man's Injector Test Results & P1211

2 separate issues. I suspect bad Injector o-rings based on oil consumption, CEL P1211, and when I hooked a scan guage II, I would get icp readings only around 2500 with IPR @ 54%, 7 seconds and the CEL light comes on. Very consistent, leading me to believe it is not IPR. Could be HPOP, but I am going through oil so suspect o-rings.

Anyway, ran the poor man's test before taking out the injectors to replace o-rings... # 3 & 5 are getting no click. I hear a faint buzz on 3, nothing on 5, or even fainter buzz, hard to tell.

So what does this mean? The post talks about armature plates & poppets, am I looking at replacing 2 injectors, or is this fixable?

Thanks!

It could be something like bad solenoids (electrical) or loose poppet screws (mechanical), both of which are fixable. Measure the resistance of the solenoids (sbould be around 2-3 ohms). Cheers!

I just did the Ohm test! Right around 3 for all 4 on the passenger's side. The plugs are pretty wet/oily, it that normal?

No, wet/oily plugs usually indicate problems with high resistance connections on the glowplugs (which melts the wiring and VC gasket pins). I would check out the UVCHs and VC gaskets on that side. Cheers!

I am ordering new UVCH and VC harnesses today. Also, I think a set of Injector O-rings. Patrick, I notice you post a lot on injector issues, can I ask 2 questions?

First the high resistance is in the UVCH and should be fixed with the new harness, correct?

2nd, and the reason I've been poking around on this thing. P1211. Truck is not as powerful as it should be, code comes on when I'm on the accelerator for the required 7 seconds. Not hard driving, just normal acceleration. It is very predictable. I hooked up a ScanGauge II to read the IPR/ICP settings and found that the max ICP reading I get is about 2500. When under decent acceleration, or going up hills, IPR goes to 54%, ICP around 2450. If I hold that for 7 seconds, CEL comes on, IPR goes to 30%, ICP was under 2000, maybe 1700, and truck runs worse. Not limp mode, but feels even more sluggish. Last time a I checked, I was down 2.5 quarts of oil. Putting all this together, I suspect Injector o-rings. I took out IPR, changed rings and cleaned it a few months ago. That improved it quite a bit, before the light would come on much sooner, so my 2nd guess is IPR needs to be replaced, but that would not explain the oil. Your thoughts?

I'm thinking I want to replace the O-rings, cheap job, I'll learn some things, see what happens. Clearly I need to do the VC/UVCH anyway, so what the heck.

Thanks!
