I got a 91 xj 4.0 5 speed that I was driving when all of a suden it lost spark. I checked for spark going to the coil and didn't get any. I changed the coil and the wire and still no spark. Where else should I check

So I tested it and its fine. Were are the grounds that afect spark. Im thinking it mite be one of them

Humbywumby

check your fuses. mine just did the same thing a couple days ago, i changed the CPS but still wouldnt start and when i checked the fuses it had blown the Engine control 1 fuse.

Checked the fuses in the engine compartment and there all fine. Are there fuses under the dash that could be affecting it or how about which grounds could cause that
