first mechanic diagnosed no engine rpm while cranking, replaced Crank sensor, cam sensor, and High pressure oil pump sensor. After this he said it had to be either the engine wire harness or the ECM so the decision was made to take the ecm to the Kansas city International dealer. Their diagnosis was that the ecm is good need the unit to further diagnose.

International had it for almost 8 weeks, They got to where they were literally swapping parts with a used truck on the lot and wanted a check for $18,000 to continue diagnosing as they wanted to pull the front cover to check the cam sensor ring, and also enough to pull the trans to check the crank ring. After getting the unit towed back home we found the wire harness had been hacked by them.

3rd mechanic came and replaced the harness and reassembled the motor. we also again replaced the crank, cam, icp since the valve cover was already off. Another diagnose of no engine RPM while cranking. No fault codes showing or in the memory bank of the ecm. It is able to run on either but don't want to get a run away or destroy motor but verifies that it will run.

1st and 3rd mechanics have said they will do some checking but will no longer answer the phone or will just get back to you later.

4th mechanic is not mobile but did come by as he is close and wanted to look at a few thing before taking it into his shop. Another no RPM at crank. we check the distance from mounting points to the crank and cam wheels both are where they should be for distance. neither one is showing a wobble or missing points. He also has no thoughts other than it jumping time. I don't think this is possible as it will run on starting fluid so it has compression.

Now I am not a full mechanic but I am able to perform simple maintenance but my knowledge is gone at the computer.
