the motor will not start up, it turns over but will not start i checked the relays and fuses all appears to be good, but i'm not getting any spark from the coil at all. I have changed the coil already and still nothing any help would be appreciated.

Computer might be shot.

Is the check engine light on?

No the check engine light has never come on, its just amazing that dodges computers go bad so often

Check to see if the fuel pump is running while cranking the engine,if your missing spark and fuel pump I would suspect the crank sensor,PCM will not fire the coil or fuel pump without a crank reference.You should have fuel pump at key on for a couple of seconds if this is the case,but none while cranking.Its cheaper than a new computer and not hard to try.let me know,have some other ideas.
