I have a 99 TJ 4.0 with 87,000 miles on it. The other day I was on my way to work, and the engine just died. No sputtering or anything, just died. It turns over fine, and the fuel pump is working, but it won't fire. I checked the coil, and it was not getting any spark. Thought that might be the issue, so I put in a new ignition coil, but it still has the same problem. The check engine light did not come on anytime before either. Any help on where to start looking would be greatly appreciated.
