No spark from coil to spark plugs

[JoeRacine]

Its a 2001 Dodge Ram 2500 4x4

I have replaced the coil, ignition, distributor cap and rotor and crankshaft sensor and I'm still not getting any spark from the coil to the spark plugs. The engine turns over nice, but no spark. What else do I need to look into?

Someone said the computer may be out. I need someone with more wisdom to answer this one.
Thank you
Joe

Check the ASD relay in the PDC.

Is your truck gas or diesel?

Key on check for 12 volts at the two wire coil plug. If you have power use a test light clipped on to battery power touch the probe to the other wire (not battery power) check for a flash while cranking.

No power to coil check ASD relay as mentioned. If you have power but no flash the PCM is not firing the coil, the next step would be to verify crank signal to PCM from sensor, I know its new but doesn't mean its good. Could also be a crank sensor wiring problem.
If you do have power and a ground flash but no spark at coil the coil is bad. Spark out of coil but not to plugs a wire, cap, rotor or distributor not turning.

Has to be gas having a coil, cap and rotor

Diesels don't have spark plugs ...

Edit: I see where you would have been confused, his profile does say it's a Cummins, my bad
