Re: [Amc-list] Anyone Around Charlottesville VA know anything about96Dodge Truck with 3.9 V6?

[Matt Haas <mhaas@xxxxxxx>]

It sounds like you need to assume it is all wrong (except for the stuff 
you've already tested). You still need to go through the diagnostic 
flowchart (you'll only get that from a factory manual) before you write 
the ECM off. It is possible to have a bad sensor circuit fry the ECM. 
The only way to find that is to go through the diagnostic flowchart. You 
shouldn't need anything more that a good multi-meter and a boatload of 
time to do this. Once everything else checks out, it would be time to 
replace the ECM.

I just looked up your truck on http://www.chryslerpartsdirect.com and 
they want $911.25 for the ECM so if it went bad before, there's a good 
chance you have a used or rebuilt on in it now. Advance's web site lists 
the ECM you have below (Neihoff # ECC2158MU, $235.99).

Transmission wise, a 42RE was used on V6's. I don't know how you 
identify them but a factory manual will likely show that. This is a 
computer controlled transmission so if the wrong one is in the truck 
now, it may contribute to problems.
