the engine control fuse keeps popping on my girlfriends 1993 cherokee. we put a bobby pin in place of the fuse to get us home but on the way it was like someone was turning the key on and off. the engine kept turning on and off by itself going down the road and wouldnt idle. and when the fuse blew i turned the key on and couldnt hear the fuel pump turning on. this is her dd and i need to get it on the road and back on off road asap. please help thanks

 

P.s it did run normal for a few miles but when slowing down it would pop like it would if you were downshifting a manual trans.
