Replaced the CPS and IPR connectors and installed an International CPS. Truck was running much better, boost seemed to come up quicker.
Then got towed home again tonight .
Ok I remote start the truck and it fires up and then dies. I restart it with the key and fires right up and seems fine. So I drive 45 miles and during that ride it hic-upped once but didn't die. Came out of my meeting and the truck fired up but then died. Spend an hour doing that then swapped out the CPS (yes the new International one) and put the Autozone one in. Same thing start run a little and die. Another 1/2 hour goes by statring/dying and then it's OK, just keeps running. So I head off home down the highway and about half way home it dies. Same thing start and die. So I called AAA and $75 later I'm home typing this (I'm only a basic member but that Gold membership is looking good now), better than my last $250 tow home.
So please someone help me out here:
1. Did a buzz test and all sounded good (this last weekend when running good).
2. Did contribution test and it passed, no codes (this last weekend when running good).
3. Truck is giving me a P0344 (CPS) code but not everytime it quits.
4. Sometimes it fires right back up or like now it is very hard to start.
5. ICP per scanner is well above 500 PSI during cranking.
If the thrust washer for the cam is bad wouldn't it go bad and stay bad (cam moves away from CPS sensor)? Per the manual the gears are helical cut which would force the cam one direction all the time.
A buzz test and contribution test confirm my IDM is OK correct?
If I had a bad injector "O" ring would it come and go?
What about a bad poppet, would it come and go?
It justed turned 241,000 miles and I noticed over the weekend the truck has a remanufactured HPOP on it. I bought the truck with only 45,000 miles on it eight years ago and have never replaced the HPOP so it must of been done prior to me owning it. It's only been to the dealer once under warranty for an oil rail plug leak.
Would a bad HPOP come and go?
