A week ago I started to have an intermitant problem with the air bag light. Now it just stays ON. Shut the truck off now, no start. Jumped the solinod still no start. Thought the ecm was bad got a rebuilt one, but still no start. Thought it was the ignition switch because with the key switch in the on posion the accessory leads had no power so I changed out the igntion switch, did nothing! next step i was thinking neutral safty switch?

 

Does it crank?

 

BTW, better place for Cummins related problems -> https://dodgeforum.com/forum/dodge-cummins-diesel-88/

 

yes it cranks when you jump the starter. but there is no power coming from the solenoid wire.

 

oh ya my power windows don't work either

 

If you flip the shut off solenoid and crank it over by jumping the starter, it should run.

 

Just remembered, I've had neutral safety switch connector to fall off twice, there really isn't a single locking tab to hold it in place. So that's something to look for.

Airbag light might be related to a broken clockspring.
