Jeep keeps blowing auto shutdown fuse

My 96 jeep grand cherokee ltd ran fine until this morning. Went to leave for work, came to a stop sign, hit the brakes and it died. Found that the automatic shutdown fuse was blown and replaced it. Started fine but got to the stopsign again and it died. Have replaced the fuse again but as soon as i try to start the car it starts for just a second and dies, blowing the ASD fuse again. Any idea what might be causing this?

    start at the fuse box, see if you have a blown 20 amp fuse in the number 20 position spot, if blown, look under the body of your jeep for a bare wire most likely connectedto the oxygen sensor goinginto your cat converter

Yes I had the same problem. The wires that plug into the sensor at the catatytic converter were rubbing against the drive shaft untill they finally wore through causing the short against drive shaft. repaired wires and it fixed everything

    i checked the wires for the sensor as you guys suggested, and sure enough, that was the problem with my jeep not wanting to start. The wire wrapped around the front driveshaft and rubbed itself bare, causeing it to short out against the body,thus blowing the 20 amp fusein the power management box under the hood,too bad i didn't read this sooner, before i spent 40 dollars in new parts for TPS and new coil... but i am happy once again ready for more fun miles ahead,my old girl has 265k in miles and still runs as cherry as the day i bought her in 1996...Thanks from Plainfield Illinois...

We have also had this problem this week over the last few days, on the passenger side of transmission we found the neutral safety switch just before the catalytic converter wiring harness and wires were melted and frayed so check there also

Wire that runs down the right side of engine as you look at it from the front of the hood. The wires are covered in conduit, but the wire is exposed to the side of the manifold and shorts out the fuse each time it touches the metal.

Check for any wires that may be grounding out causing the fuse to blow...

If the crank sensor is failing, you should get a check engine light and a trouble code for it.
Have you had the computer checked for trouble codes ?

97 jeep cherokee blows fuse #11

I think fuse 11 is transmission control module, powertrain control module, automatic shutdown relay, fuel pump relay.. most likely it could be an issue with the wirings from the tranny. Check this one out before opening the conduit

1996 Jeep Grand Cherokee...Blowing ASD fuse

My daughters jeep had the same problem. We fixed by finding the wires that run beside the manifold down under the car. The conduit that have the wires in it was worn away because of resting up against the manifold, causing the wires to short the system out. Once I replaced the conduit and taped the wires it has not shorted out again. By the way, the Jeep dealer couldn't find the problem.

Sounds like a bad ground.Check for broken connections or corroded terminals especially around the battery as acid tends to seep from them and corrode the connections.
