Hi my name is Brian and i have a 1997 Chrysler Concorde LX 3.5 V6 with a little over 86000 miles i drove my car home and shut it off went in the house for a few minutes and came back out and tried to start it and i had nothing no power at all so i got another battery and now i have power but no spark the car will crank but will not fire do to no spark i have changed the ignition coil i have changed both the crankshaft and camshaft sensors i have checked all the fuse's and relays and i had the alternator tested and i have fule and the check engine light is not on so what can be my problem ? Can a bad ground strap cause no spark ?

 

power and ground to the coil pack?
