Our TJ has ALWAYS run great, 4 cylinder and all. The other day I was fiddling with a loose radio connection and shortly thereafter took it for a short ride up town. It was running great, then the engine shut down. It would crank over, but not fire and the #19 accessory fuse keeps blowing. I unplugged EVERYTHING to the radio, replaced the fuse with another 20amp, and it blew again. And again. I tried a 30amp (out of frustration and stupidity) and it didn't blow, and didn't start. Second attempt it did blow. I could sure use some advice. Thanks!
This is a great forum, as if you didn't know that already.
never put a higher amp fuse in the spot of a lower. It's there for a reason. To protect electrical components. If it keeps blowing theres a prob like a short.

Skip that fuse for now and check all your other fuses behind the glove box and in the distibution box under the hood.If it isn't fireing at all it has more than likely blew a fuse to the ECM/PCM or your distributer isn't getting a positive feed.
