Hey everybody I have a 98 mustang gt that about two days ago i had a clutch installed on it. After the clutch was installed the mechanic (local) drove it up to the front of the neighborhood where it completely shut off on him. Now the engine will crank but not start and also the theft light is blinking rapidly when turned to start. We searched for the problem for hours and found that the yellow 20 fuel pump fuse would blow when the key is turned to iginition. I checked the fuel pump switch in the back and it pressed down. Seems like the car thinks it is stolen so when the key is turned, it turns it own fuel supply off. Im trying to stay away from taking it to shop for money reasons. DOES andybody have ne advice or tips ?
 
have a new key programmed for it

I dont think the key has anything to do with it. When I had my 01 GT, my girlfriend went out one day and had a new/spare key cut for my car, not knowing about the chip inside the key. When she tried starting the car, it just sputtered. It never blew any fuses like the OP mentioned :shrug:

It definitely sounds like the PATS though.
 
Well i just figured out the 1998 mustang gt manual is wrong and it is actually the PCM fuse that is blowing. do u think he could of shorted out the mil eliminators putting the transmission back in?
