There are instances were the Dodge Ram starts intermittently. In other words, the truck engine starts up at irregular intervals or occasionally turns on. It could even start momentarily and then stall. In situations like this check and test the fuel delivery system components.

Specifically you should be certain there is sufficient fuel pressure. Make sure there isn’t a restricted fuel line. Check the fuel pump relay, and determine if the fuel pump inlet strainer has blockage. Use a test light to insure power is making it to the fuel pump. Lastly, test the fuel pump.
