Check the main fuse on the PDC first (the first one like a 140 AMP or something).
If everything is good and you have power there then I'm thinking PCM as well. You can pick up Pre-Programed PCM's on ebay for like $200 shipped and ready for direct bolt in!!!!

Blowing a fuse at the PDC sounds like a voltage issue. Have the alternator checked then check the grounds, then a possible PCM.
By the way<------A ECU is a Ford name and a PCM is a Dodge name for the same part (comuter).

BTW: comuter is actually spelled commuter, and is someone who travels to work/school/wherever else they need to everyday, a computer is what controls the engines on out trucks

Okay so I told her to start at the alternator and then check all grounds first. Then she told me the whole story
I hate that!! So apparently she is having the tranny replaced as the og went out. In the meanwhile, it has been intemitently(spellcheck Dr. Sharps) has not been starting guages dead, no fuel pump, no codes, but she has not seen "NO BUSS" yet and mileage in odometer has not blinked with KOEO like mine did. Fuel pump replaced twice and relay replaced no help. 3 140 amp fuse blew one after another when installed. Hope this helps the diagnosis. Should the start still be at the alternator then grounds then possible PCM replacement or could there have been issues caused by the tranny swap??Thanks again all wise ones!! Your help is always greatly appreciated

A thousand pardons to the Mopar faithful!!!! I changed a speed density ford to mass air and it is stuck in my head, aven though I changed the PCM in my own Durango LOL I'll get it right eventually.

LMAO @ Dr. Sharps....... 
Ok, there is a serious short. You are going to have to find out what is causing the fuse to blow first. You might have to pull everything out (take picture first) then slowly replace to narrow down the area of draw or do a continuity to ground to possibly find it.
A wiring loom may have been pinched during install of the transmission.
