if they were bad wouldn't a scan gauge pick up these codes?

 

Probably not. See post #14. Scangauge is a BAD code reader.

No sync on CAM/Crank sync might be an issue with the cam sensor or the crank sensor. If you can read an rpm (150+) when trying to start, then probably the crank sensor is ok (they do not fail often). No sync with a good rpm signal might mean a bad Cam sensor.

Have you read the no-start sticky? I put a lot of detailed, but methodical, steps in it. It even has some tests for the Cam and Crank sensors.

 

I do have 150+ rpm, does that completely rule out the crank sensor? I've went thru the sticky again and could not relate anything to what im experiencing. everything is looking ok ficm relay fusible links pcm and gpcm all look good not sure what else to look for

 

IIRC the list I had would take you to troubleshooting the cam sensor next. It should have links in there to do so.

If not, here are some steps:
Troubleshooting CMP Wiring:
Measure the resistance between the PCM engine connector pin 31, harness side and the CMP sensor pin 1, harness side; and between the PCM engine connector pin 43, harness side and the CMP sensor pin 2, harness side.
To check the sensor itself:
You can check the red (pin 31) and orange (pin 43) wires at the PCM center connector. Using a multimeter that reads hertz check across both wires while cranking, you should see around 1.3 Hz.

gonna go over the cam and crank wiring and check for bad connection, oil etc.

 

it was almost imposible to get the cam shaft plug off. had to unbolt the sensor itself slide it out to unplug it. looking up the pin diagram for the pcm connectors ill let ya know what i find.

 

what is the is the name for the connector for the engine pcm i could use a diagram

scratch that... I have continuity on both 31 and 43. do we assume now its the actual sensor?

 

I was hoping to see a resistance reading and a frequency reading - 1.1 - 1.9 Hz when cranking (between Pin 31 and 43)

That said, the part number is 8C3Z-12K073-A. It isn't very expensive ($30-ish)

Make sure there isn't any corrosion on the flange face where the sensor plugs in.

 

i can conduct that test in the am and get back. i never thought to crank it since i removed the censor already.

 

I thought that the cranking test for frequency was described in the pdf I attached. After checking, I guess it wasn't. It needs to be done w/ the sensor in. I added it to the post above for future reference.

If it were me, I would just replace it since it is out already.

 

Changing it out tomorrow! ill let you know the results! thanks again for all the help!!

 

6.0L cam sensors don't go out very often, so when they do it is almost down to the process of elimination (except for the tests mentioned previously). Codes can often times provide a clue that can help save some "guessing". For any future issues, that is one of the first things to do - pull codes using a quality scan tool (ForScan or ForScan Lite recommended).

 

i hope to report back with some codes. otherwise ill be stumped. so if those test come back ok will that rule out the wiring? im assuming this test is to be done with the sensor plugged in, taking a reading from the back of the connector?

 

Yes - you can back probe the PCM connector (middle connector).

 

so i got the forscan app and bafx and have something.. the p0113 since i have the filter and stuff removed. it says
DTCs in GEM;B1318 P1832 B1483
DTCs in IC: b1352-20,U2023-20, U1900-20
DTCs in RCM: B1318
i still have the cam sensor unplugged as well and did not get any code for that. i attempted to run the injector test, it says it passed but i never herd anything from the injectors at all.
my patience is running thin on this truck =(
gonna test the resistance ill let you know what i find
