i have a 2002 Durango the thing will just die and turn off no fault codes except no buss on odometer. New tps map sensor ias cam and crank sensor. When it dies I have 5 volts on all sensors, 48 psi fuel pressure 12.9 Vdc on battery alt putting out 40 amps with everything on. I’m lost, the engine relay is good, fuel relay good. It’s a 4.7 4wd. Transmission filter just changed. Please help!!! Looked for air leaks, wire shorts nothing found.

 

When "No Buss" appears that means the computer is going out.

 

Thanks that’s what I thought

 

Wiggle the PCM connectors and see if you can duplicate the problem.

If it only happens when the engine is hot, I would start with cam AND crank sensors.

 

Thanks for the help, it was the pcm. Changed it out drives like a new one thank you...
