i have a 97 cobra mustang, it was running fine till the other day me and my buddy checked some fuses on it without disconnecting the battery terminals (dunno if this could have triggered my problem) and now the car wont start and isnt getting spark, i changed out the crankshaft position sensor and the camshaft position sensor thinking that was my problem but i was wrong, ive checked most of the fuses and all seem to be well, my next guess would be coil packs but im not sure. the car does crank but doesnt fire i would appreciate any help
