I have a 2001 Dakota rt with pcm issues it started not getting fire to the fuel pump sent it off to be fixed it lasted about a week then whenever it got to a certin temp or I would go to slow down to stop it would cut off they sent another one put it on and with that one I was not getting fire again put the other back on and now it does the same what else could be the cause or do they just don't know how to fix them thanks eddie

 

Welcome to the forum Eddie.

Some of the rebuilt PCM's are just not "right."

How did you diagnose it with being the PCM in the first place? Have you checked the ASD relay? It kills the power to the fuel pump.

 

a friend put his scanner on and it said internal component he said it was the pcm the engine relay was the only one that was out thanks for the help dan...

 

What kind of scanner? I assume you mean an OBD scanner. What was (were) the code(s)?

 

Eddie, a neat feature of your Dakota is that you don't need a scanner to pull any codes. Try this, with the truck not running turn the key to RUN (don't start it), then back to OFF, back to RUN, back to OFF, and this time leave it in RUN. Any codes will display in the odometer window.

It'll say P DONE when finished.

 

I already tried that it said no bus I have a friend coming this weekend with a factory dodge pcm that has the same part number that I need he had it flashed with my vin maybe that will work..

 

"NO BUS" means that the internal communications bus isn't working.

ANY of the components on it can cause that, not just the PCM.

I'd see what has turned up on this forum and some of the other forums on the "NO BUS" error before swapping the PCM ... again.
