The P1272 and 1274 suggest a problem with the #2/#4 UVCH.

I see the A/C clutch is engaged, or so the Solus thinks anyway. Do you have the HVAC control on MIX or windshield defrost, or one of the A/C positions?

 

No it was turned on off i thought that was wierd. I've also ordered new valve cover harness and icp so those will be taken care of. I ordered the parts i need and also was wondering if I got fittings to put a 100 psi of compressed air into the oil port in the head will that show if i have leaky injector orings?

 

The fuel pulse width is low like .50ms but ive had it high like 3.50 in a few other scans i did and my dad's truck runs about 1.50ms I scanned his truck so i could see normal values and my icp readings are way put of whack ill post his reading so we can see the difference yes his truck was running so alot of stuff will be different but can see what's close on mine and what's not.
These are the reading from my dad's 97 psd while it was cold.

 

Looked at the data on the last scan on your truck. The three parameters of interest are IPW, ICP and IPR.

Here is how it works:

IPW of 0.42 ms means the PCM is seeing good data from the CPS. When it does the IPW goes from zero to 0.42 ms. What this means is the PCM and IDM are in sync, talking to each other. The PCM should now try and ramp up the HP oil to 500 PSI or above to fire the injectors. Once detected the IPW will go from 0.42 ms to ~ 1.1 ms or above and fire the injectors.

The IPR % is at 50 % as demanded by the PCM, about max for a stock truck. However the HP oil is only at 135 PSI as reported by the ICP. PCM-IDM won't fire the injectors at that low pressure. So the question is why?

You certainly have done a lot of cranking. If not already done so look at the oil level in the HP oil reservoir and refill if necessary. Excessive cranking can drain it down causing this issue.

IPR could be bad. There is no feedback from the IPR to the PCM at all. PCM demands a certain percent and assumes its instructions are carried out. The PCM's only feedback is the ICP sensor.

Of course it could also be HP oil pump, bad injector oil rings ...

Keep the cranking time down to 10 - 15 seconds as it's better on the starter and you will get real time data. Anything above that and the PCM will go to inferred values, which means it's just guessing and the scanner will display the guess, confusing if your not expecting it.

I think you might of fixed the fuel pressure issue. Anything in the 10 - 20 PSI range cranking should start the engine.

 

Should I get fittings and blow air into the fitting on the.head to see if orings are bad I'm not getting oil squirting from the injector though I would really like to pick your brain if u dont mind ill pm you and get your number so i can text? I will also just order an ipr the truck will need these things eventually. Also I think the starter is due for a replacement it was completely loose when I got it and I assume it was from them cranking on it so much. Also the hpop reservoir is full the oil in it looks a little milky like it has some condensation in it?

 

How do I test injector orings and why aren't I getting any oil squirting out I got my uvch and icp should I replace the pig tail for the icp they sent me one with icp

 

A sign that your o-rings are bad is oil in your fuel filter.

 

Yea I don't have any oil in there just some red diesel the guy I bought it from put in it. And how is the oil being pushed back up the injector into the fuel canister?
I got the icp and uvch so ill put them in tomorrow I don't think it's gonna help. And does anyone know why my hpop is full of milky looking oil I had all that slime in the vc from condensation but is that causing it not to fire? I figured with all the info I've gotten I would of had this thing fired by now but its being a pita
And someone mentioned something about it showing my ac was on when it wasn't is that a clue to something going on?

 

Any reason to replace pigtail if it's ok and clip isn't broken just clean with some brake clean?

 

The condensation in the oil probably isn't causing your issues but I would start by sucking all the oil you can out of the HPOP and replenishing with fresh oil and a fresh oil change on the engine as well. Then I would hook the scanner back up and check ICP and IPR DC within 15 seconds of cranking. If ICP doesn't climb to over 500 then I would plumb shop air into the oil rails and see if you have injectors bypassing either from o-rings or hung up injectors.

 

Ok cool i will try that should I replace the pigtail for the icp? The sensor has oil on it and the plug does too but i figured if I cleaned it with something it would be fine. Is there a drain plug on the hpop reservoir?

 

There isn't a drain plug. I use some 1/4" plastic air brake line when I drain mine. It is slow going with cold oil and it isn't fun to fill either. I am going to pick up a big syringe and rig a hose up to that so I can suck the oil out and the suck oil up to fill it as well. If you have oil that had wicked it's way up the ICP pigtail then the oil will eventually cause the insulation to buuble/degrade on the wiring.

 

Ok so ill check it out and replace if necessary should I solider or butt connectors?

 

Solder.....

 

Check ignition relay under hood and your key switch in the colum if you haven’t already, remember go through the basics before mechanicals, has the truck been altered From stock? Or any head work done?
