Ok so i put a new short block in my dakota R/t. When i pulled the engine i forgot to unplug the Crank sensor so i had to replace it. Anyways i have everything put back together and now i don't have a good spark on a few cylinders is sparks every once in a while. I have a new cap rotar wires plugs i tested the fuel pressure and it all checks ok i put a new cam shaft sensor as well. Thanx a bunch i need some suggestions i need to get my baby running again

The problem might simply be more resistance in the circuit than before. Since you changed the cap, rotor, plugs, and wires... you changed a lot of variables. The gapping on the plugs might be too great for the spark to jump across. Try using a small tack hammer and closing up the plug gaps a little bit and see if that makes a difference. I had to do that to my brother-in-law's truck after giving it a tune-up.

i'm sorry i mean it doesn't even get a spark from the wire or even from the cap

Welllll... my only guess would be a bad rotor or cap then. Sorry for the lack of help man.

are you sure the rotor is on flush and not crooked i have done it bofore and kicked myself in the *** for a coulpe hours. it will sparke on the ones it gets close to and no tthe other half that it doesnt. also check the bottom of the cap and see if its rubbing anywhere
