You did lift the cab a few inches right? I found they go in pretty good with the front about 4-6" lifted.

Not sure about the tach.. pinched wire somewhere?

 

Yeah I did jack the cab, also left the motor mounts off till it was in place. I think I figured out the cam sensor issue. here is my spin on this. OK I have a 99 block, with the 2001 head, all my electronics are 2001. I think my cam shaft gear has not got what this engine needs, remember the 2001 is the only year that does not have a crank sensor, so the cam gear is doing 2 jobs, thus is must have different mag pick ups to be able to do this. I checked the voltage at the cam plug, I have the 5 volts needed, I function tested the tach it jumps when the wires are touched, so the only thing left is the cam gear. they have to be different. What you think ?

 

Mechanically speaking, with a cam position sensor, you don't NEED a crank position sensor. The engine turns at 2x cam speed so when the cam pickup is at the sensor the crank is always at the same position.

That said, I don't know if dodge did anything weird. If the part numbers for the cam position sensor are different, maybe. If the part numbers are the same then there shouldn't be a difference IMO.

 

To think when I started this I could not even spell Cummins ! and now I have learned a lot about these engines, I copied from my other post and put here also. I wanted to share what I learned about my little Cummins adventure. Hope it can save some one time and headache.

OK Gearheads, I found the rat in the wood pile. Not from calling Cummins tech support not through Dodge dealers. I got tired of the unknown and just pulled down the front of the 2001 engine (blown up) and removed the cam. then pulled down the front of my 99(running in truck) and then it all became very clear why my 99 engine would not give my 2001 computer the correct tone signal to operate the cam/crank signal. the 2001 cam gear is in fact the same. With the exception of a triggering wheel bolted to the back side of the gear. the 99 is just a gear. so the 2001 computer was waiting for the correct tone from the cam sensor but never could get it. it simply got nothing but a TDC signal. I wanted to share this with the Cummins world, no one should have to go through what I just did to find out something that should be common knowledge with most any reputable dodge dealer/ shop. Love the engine, hate the control system dodge has put on such an amazing engine.
