1999 Dodge Ram Engine will not turn over

Hello, did you check fuel pressure with a gage? Have you tried starter fluid in the intake? There are safety issues using a flammable spray, that is your responsibility. I usually take the air-duct loose from the throttle body, open the throttle valve, spray a little, see if the vehicle will run off the spray. If it does, I suspect a fuel issue.

I don't remember the year, I seen ram pickup with digital odometer and the codes would cycle up on the odometer. I think it was a 2K model, don't know if that would work on 99.
