Re: Jeep Starting Issues

The fuse that was blown, is it the same one which was blown before? Either way, a fuse doesnt blow for nothing, its protecting the wiring for overloading and eventual melting. There must be a too large current or even a short, which causes the fuse to blow. If not done yet, i would replace the fuse again with one with the right rating. Putting a higher rated fuse in can eventually get you home, but it could also result in melted wire isolation, burnt wiring or in worst case even fire.
The ASD circuit is feeding all coils, all injectors and the PCM. There is also current going to the O2 sensors and the hydraulic cooling module, but that circuit has a lower rated fuse after the ASD relay, which would blow if there was a short overthere.
Did you check all the wire bundles for shaving in the engine bay? Especially the ones around the cylinder heads.
