After working at the hunt camp, I came back to a flat tire. Started the truck and pulled it to the back where the air conpressor was and aired up the tire. Went to start the truck and nothing. On my edge cs it is showing codes p0299,p0336,p0480,p0528,p0671.
I don't have any cell service there and im headed home to get my scan gauge but I need some idea to check. Battery voltage was dropping from 12.6 to 9.2 on start up, and I didn't get any oil pressure registering on the gauge from about an 8 second crank. It was hooked to a dodge diesel with good cables after I drained the batteries some and still nothing. Truck has 190k miles. Only aftermarket parts is a bulletproof egr cooler and a coolant filter. I will also bring back a multimeter to check ficm voltage when I return. If anyone can give me a list of values to check on scan gauge, it would be greatly appreciative. I know one is a glow plug circuit cylinder 1 code, and also a ckp sensor circuit range code. Could the glow plug cylinder one cause a no start?
Thanks, Anthony

 

I would check for icp while cranking, should be 500 plus. Also check to see if fpw registers anything more than 0. You should be able check ficm voltage with the scangauge with the right x codes loaded. Battery voltage dropping to 9.2 is pretty low, might be the culprit there. Without oil registering after 8 seconds of cranking is interesting, but if it ran fine when you parked it, I would start with some fully charged batteries.

 

Icp +500
Ficm +48 both key on and cranking
Fpw is zero
What does that mean?

 

Fmp 48.6
Flp 10.0

 

Ipr 14.4 koeo 77+ koec

 

Fpw is fuel pulse width. With it staying at zero means the pcm is not trying to open the injectors. With icp over 500 this leaves cranking rpm min 100, cam crank sync and ficm sync. Pull up rpm on the scangauge and see if you have a value while cranking.

 

Rpm is 64 max

 

Does it sound like it's cranking slow?

 

Even when it's hooked up to another diesel truck
We did get it to 84 rpm
Battery charger set to cranking amps on one battery and diesel truck on the other
Definitely dragging

 

Let them charge for a while, need cranking rpm over 100. Do you have sync programmed into your scangauge?

 

Also check fuse 22 under the dash. there is something wrong with your fan wiring, at some point it shorted, this will blow this fuse. Unplug the fan for now and check the fuse. Forgot to add that earlier, 2 codes for the fan, one for a shorted circuit and one for no fan rpm.

 

Syc is 0 so that means not in sync correct?
Could this be as simple as a ac conpressor pulley dragging or starter maybe? But it's wierd it started right up to move the truck then 5 minutes later, nothing!

 

Fuse 22 is good

 

Take a very close look at the pigtails for the cam and crank sensors. Also look for chaffing on the wiring harness. The crank sensor is behind the ac compressor on the passenger side and the cam sensor is up front midway up on the drivers side. The sensors do not fail very often.

 

Pulled batteries and brought them home
Will load test tomorrow then work on it again tomorrow afternoon.
Thanks for the help so far
