I have a 2001 dodge ram 4x4 with a 5.2 the truck will run good then you can cut it off and go to start it up and it will just spin over and over if I wait about 30 mins and then it will start right up but it will have a slight skip to it. the truck has gas to the motor it but no spark. it has no cel on and it has 140000 miles on and about a month ago I put new plugs wires cap and button in it what could be making it skip and not fire up at times

No spark would tend to point at the crank sensor.

 

Ok it did id agen last night and the cel came on I so I resit the pcm and then it fired right up

 

Did you read codes before the reset?

 

no I had no way of reading them

For future reference, the 01's let you do the "key trick", cycle the ignition on, off, on, off, on, and codes will display on the odometer.

 

next time ill do that thanks man

Parts stores can read the codes for you, and a basic code reader is pretty cheap. I recommend getting one. Knowing the code that was set is important to proerly diagnosing failures.
