The 1998 – 2002 Dodge Ram 2500 & Ram 3500 series vehicles were equipped with the New 24 Valve Cummins engines. They utilized a VP44 injection pump which was electronically controlled by a Cummins 1 plug ECM P/N 3942336 (Engine Control Module)or FCM (Fuel Control Module) that mounts to the side of the block hence the terminology block mounted ECM. 

The 1998 & 1999 model years had issues with the “Wait To Start” Light not turning off. When that circuit doesn’t complete the vehicle would not start. We can fix this Cummins ECM before further damage is done to the ECM. After Prolonged “Wait To Start” problems this Cummins ECM will eventually burn out the main processor in the unit. Most other rebuilders do not replace the processor, that’s why you have found Module Experts. We can also fix this if it hasn’t damaged the main board in the unit which is not repairable.
