No start

[x148]

Greetings everyone,

I got a call about a 2005 F350 6.0 that wouldn't start. I asked what happened, he stated he pulled into the parking space inside the parking garage and started to rev the engine to show off some soot for his lady friend. As the truck was reving up it immediately shut down and wouldn't restart. The kid tries to start the track shortly after with no luck. I checked DTC and only came up with P2614 Camshaft Position Sensor Circuit OPEN. I then picked up a new sensor, installed it and no start. I even tried a little sniff of ether cause the batteries at that point where getting weak, no luck. I then tested the FICM to find out that it was under the correct 46.5 Volts. I had the truck towed to my house, I picked up a new FICM (58V) only the bottom power supply half. I installed the FICM and sure enough no start, I got the correct volts this time. I then pulled the old IPR valve out to find that the screen was broke and figured there was some debris inside clogging the passage way. Rifled in a new IPR and tried to start with no luck, Checked for codes and still getting P2614. I pulled all the information from All Data and tested the harness, sensor etc etc etc. I then cut the wire to the cam sensor and spliced in a new wire directly from the sensor to the PCM/ECU. Truck trys to start and sounds much healthier but still wont turn over. I am no longer getting the P2614 Camshaft sensor code. The gauge for the oil moves up after cranking for a few seconds, I feel that the HPOP is still in good working order, I am wondering if maybe the STC fitting broke or if there is another related issue which is not allowing the truck to turn over. Any idea's or guesses at this problem would be greatly appreciated as I am tired of working on this truck.

At one point you say it won't start and a another that it won't turn over?
Please clarify to the current problem. If he really had his foot in it he may have blew something and you now have a new problem, STC; dummy plugs etc. You need to verify current HP oil pressure, fuel pressure etc.

Something took out the IPR. It is possible multiple conditions came together. The FICM was probably an opportunity find. You need to determine the ICP to proceed.

revving the truck can be death to a weak STC fitting

The P2614 is usually caused from excessive cranking, unless it keeps popping up or is on all the time I would disregard this code.

Air check the high pressure oil system the ipr screen usually blows out then the t fitting (stc) blows

I got a brand new IPR in, I swapped ICP's from my truck to the down truck. The camshaft sensor won't go away. Sorry, to clarify I turn the key the truck is cranking but won't actually run. I have had it on the trickle charger for 24hrs and the batteries are strong now. I checked all the pins in the FICM, PCM and did the test procedure that I found in All Data. I will air check the HPOP tomorrow, i tried firing it again tonight and finally got a new code, P0335 Crankshaft position sensor (CKP) CKT A. I plan on swapping these sensors with my KNOWN good working sensors and see what I come up with. Thanks for the quick replies.

Excessive cranking with no start can throw cam and crank sensor codes. I would persue the HPO system, seeing as how the IPR screen was blown.

I air tested the oil system and found a leak near the pump, when i pulled the pump I noticed the STC was junk. I replaced with the new upgraded fitting and went to fire it up and got nothing. I figure the system was air bound but ive cranked it for 20 second intervals about 20x and got nothing so far.

Did you re air check it once the new t fitting was put in?

I did air test once again and found zero leaks, now im wondering if the pump is bad itself. I feel bad cause ive had this vehicle in my garage for almost two weeks and id like to get this vehicle back to the customer.
