Can vapor lock blow fuse to coil pack?
Having lots of problems. Started with jeep sputtering, then shut off. Fuse was blown to coil pack, changed fuse, blew again. Changed coil pack, jeep still runs awful. Changed crank sensor, cam sensor, finally changed computer, still wont half run, keeps stalling, sometimes maybe 30 mins, sometimes maybe 3 mins! Please help! 2000 Cherokee XJ

Do some diagnostic work and find the problem, throwing parts at it won't fix it without paying for unneeded parts. The fuse is blowing. That means you have a short to ground. Now look at the wiring foe the circuit that keeps blowing the fuse. Once you find the wire that is shorting out, fix it. It could be the O2 sensor wires melted to the exhaust manifold causing the problem. But YOU have to look. WE can not do it for you over the net.
