P0251 6.5l please help.

[Trucker2k16]

I even did the every 50 key cycles

 

[Trucker2k16]

And????

 

[Trucker2k16]

Put a new resister and moved pump to passenger side like .002 thousands

 

[ak diesel driver]

So it was the resistor. Have to log that in the ole memory bank. Glad you got it figured out

 

[Trucker2k16]

Yea i wrote it down to thank you everyone for the help you guys rock

All this time, we thought that the PMD resistor is NOT important.

It looks like, we prooved that bad resistor will cause the timing to be messed up.

Wow. Feel so bad watching you go through all that. So happy you are through it.
Honestly not being a jerk, but really- just look at the ease of a db2. I can’t do ds4-db2 here because of smog regs. If i could my wife would have a 99 tahoe with db2 in her driveway and I would still have my 99 truck. The pmd is the worst thing to ever happen to the gm diesel imo- more than the converted 350 gas engines things.

Stand alone trans controller is best but most expensive part for auto trans.

Bobbie Martin did a book on it showing how to including using tcm (like ecm without as much info) from other vehicles instead of stand alone- but imo costs are close enough that stand alone is worth it.

junkyard throttle pedal and cable from any other gm pickup can be adapted but the 6.5 93 and older obviously fit perfect. Hot rod supplier gas pedal with cable is good option too.

cruise control from older truck also is you want it.
Maybe 3 or 4 wires on engine miscellaneous places.

I really wouldn’t do the swap at this moment now that you just fixed everything under the sun. But if you slowly gather junkyard parts as you go- next time the world goes upside down and you need a new ip...

See... all one part system is calling your name. Just copy your db2 rig into this one.

Here the diesel smog gets done through the obd2 port if equipped and that it the downfall here. If your place smogs via tailpipe or not at all... I know what I would do to that shiny red truckzz
