05 F-550 intermittent no start cold. P2614

[Matt Saunoras]

I can't for the life of me verify this concern or come up with anything suspicious. I messed around with this truck for hours yesterday, let it go on it's merry way and it's sitting in the parking lot waiting for me this morning. The cust thinks it's a glow plug concern but it's been 80 degrees F all week. Not to mention no glow plug related DTCs.

 

It kicked one DTC, P2614. I understand that if the CMP and CKP output codes are in memory I should disregard these(due to extended cranking) but this truck only has one code in it.

 

Within the last 2,000 miles this thing has gotten coolers, a rad, fan clutch, all 8 injectors and a ficm. I put a cam sensor in it when I did the coolers, at tne time the sensor was leaking and a P0341 in the memory, no related concerns since then. It also had a cam sensor done under warranty many years ago for the same P0341.

 

My question is the P2614 a good place to start? As many times as I've heard about 6.0 harness concerns I've never actually run across one.

 

Thanks

A persistent cam code issue has always turned out to be rust on the block, for me anyways.

I'll give it a shot tomorrow if the thing isn't verifiable a no-start in the morning.

 

Ran the engine tonight with the intake off and wiggled and pushed on every spot on the harness I could find, even down by the sensor. Too scared to pull the sensor out at home, I don't want it breaking off.

This little bit of rust on the right side of the cam sensor mounting boss.......

 

 

caused this......

 

 

Which caused cam codes and all sorts of troubles. A deburring bit on my whiz wheel made short work of the problem.

The last no start I had was an in range bias on the ICP sensor. No codes present. .86V, 580psi at KOEO.

 

If P2614 sets with extended cranking, then I'd look elsewhere..

[Matt Saunoras]

Still can't verify this no start. Cam sensor mounting boss didn't have enough rust on it to matter. A little rubbing with some scotch brite and it's all clean.

[Matt Saunoras]

No idea what fixed this truck but it hasn't been back. I did clean off the mounting boss even though it didn't appear to have enough rust to matter. Who knows

 

oh yeah, and I tossed in a known good ICP sensor for good measure. Shotgun diagnosis
