I put new plugs and wires on my car today, went to start it and blammm.. didnt start.. So one of my friends came over with a 95 ex, we threw his distributor on my car.... Walahhhh it started, so he put the distributor back on his car and blam, didnt start... After a thourough check we found out his coil got fried, which led me to find out my coil got fried too.. I didnt have any problems until i put the P28 into my car "d15b swap in 94 dx coupe" Anyone ever have this problem or have any idea whats shorting out the coil..???
