Hello all, 

I too am in a similar situation with my truck.....I recently took ownership from my uncle, who recently passed away and left it to me. I would normally never own a diesel, but as I mentioned....it has much sentimental value to me, I have to do my very best to honor my uncle.

That said, he had spent a large amount of money on the truck, he has all the bells and whistles you might expect, the Quadzilla system, the exhaust extras from Bulldog and on and on it went. I am not very skilled at mechanics, but I am a cheap man, so if I can do it myself, I will. Still, the problems seem to be adding up, and now the truck will not turn over at all, its obviously fuel related, I have narrowed it down that much anyway. Its a 2001 2500 cummins with the turbo and VP44 of course, and the lift pump, which is Mopar and always seemed to be operating just fine, so I doubt thats the issue. It all started last summer, ive read on here about others and their hot weather problems, and mine are all too familiar. It would start just fine, then for no reason, not start at all, which forced me to wear out the starter, an d I had to get a new one. I then attempted to change out the factory stereo......and now im in a world of you know what! I dont hear the pump come on anymore, I used to release the pressure off the fuel filter, then it would start again, but now it appears to be dead. I'm now at the point of trying to decide if its the ECM, the VP44, perhaps even the PCM all since I introduced the stupid radio in to calculation here, but the fuel issue was present before that, so I think its just run its course. I would just appreciate any help in deciding which direction to go next, as I sold my Chevy, and now depend on the Dodge...which is now got me very concerned as I read the various tales on this site.

 

Thank you in advance,

Brian

You can use the OBD 2 to check for codes. The DRB III is pretty pricey. 

If you have an android phone or access to one you can connect wirelessly and download the app.  I use this one and Mopar1973Man suggestion.  Works great.  Best $50 spent!

Good Luck.  If the PCM has been flashed 7 times maybe something is causing it to go bad?

I'm trying to figure out the PCM reflash? 

 

Shifting performance is a AC noise issues of the alternator. Just need the W-T ground wire mod. Then do the PCM protection fuse for the alternator. 

 

 

Very interesting sir, I do indeed hear a whine now after installing the recommended external voltage  bypass.....as for the wire going to the PCM, it looks like someone has used a pin, screw and wire to ground a wire to the firewall, but it is a orange and blue or black, I cant remember exactly right not....any idea what that is for?
