I'm new to the form so please excuse me if this is in the wrong section.

Problem:

2001 Ram. ECM died so I got a recon one which was coded for my truck.

After it was installed I have no power to the Heater and Fuel relays in the PDC?

There is power to the ASD relay.

I checked the Purple Wire with White Trace coming from the PCM and there isn't 5 volts.

Fuel Gauge in the Cluster barely moves when the ignition is turned on.

Any ideas why the lift pump and heater won't run.

The engine does turn over.

Thanks in advance.
