truck dies, need help

[dmoss69]

Here's whats happening.

Truck started dying, once it died, it is very hard to start back up. Once is fires back up, you have to give it 1/2 throttle for it to slowly pick up rpms. Then start driving it again, it warms up, problem seems to lessn to just a miss.

Pulled codes, these is what was in the truck:

p1212 ICP not at expected
p1247 Turbo Boost press low
p0340 Cam Pos Sensor Ckt Fault
p0732 Gear 2 incorrect ratio

I cleared the codes, ran a buzz injector test which came back no errors, checked data and injector psi is round 500 at idle to 2300 around 3/4 throttle.

I drove the truck about 2 miles after clearing codes, scanned again, and still have the
p1247.

Any ideas. I'm going out to the truck now to crawl under it and look at the wiring to the ICP and Cam shaft position sensor. Also going to check HPOP resivour.

Oh yeah, FIRST POST!

Your next thing to do is run a contribution test & see if you have corresponding injectors failing(most common is #3 & #8 injectors). This will give you a sign that it's possibly your CPS. Also check the connection on your ICP sensor & make sure it isn't saturated with oil on the plug or the sensor. If it is, get your ICP sensor replaced & run a data stream on your new ICP sensor to see how your truck's performing.

well, I found it was low in oil, so I put oil in the truck, unplugged the camshaft sensor and cleaned it with electrical cleaner, along with map sensor plug, fixed the wastegate signal line, fired her up, and she's been per-que-lating ever sense! (running like a top!)

Thanks for the forum though, I got a lot of good tips from here!
