my 97 zj keeps blowing the a20 fuse under the relay for the trany .......the problem started when the jeep just shut off and it never wanted to start again so i did the tow truck thing ,took it to my friend he has a shop ,change the coil ,distributor , fuel pump , starter , battery , relays , fuses , i just finished changing the crankshaft sensor cause it wasn't starting and i was reding the post about the crank sensor so i did it ....any how the car started and it sounded good .....until i put it in gear and off she goes.....please the only detail i can see and tell you is that it keeps blowing the fuse under the trans relay .....please help is my only car and i would hate to have to get rid of it.....i love my jeep.....

 

Might have a shorted solenoid in the transmission that is causing the fuse to blow when you put it in gear.

 

thanx man i'm gonna try and find it and see if thats the problem.......

 

Look at the obvious first, maybe the shift linkage is rubbing wiring causing the short. Maybe try unplugging the connectors going into the trans and see if the short goes away, if so then drop the pan and take a look at the wiring and solenoids.
