Question about 2003 Ford Mustang
Hi everyone! I'm at my witts end about this and just about ready to sell this car to a junk yard. Hoping someone could open up some insight or at least direct me to a crackerjack mechanic who can fix it. The car will not start. It has been acting up for a while and would die after driving it a while, but when I would pull over, kill it, and restart it would keep going for a bit. Everytime it stops working the security light blinks continuously and the odometer goes to all dashes. The shop I took it to replaced the computer and some other parts that cost me 1500 dollars. It ran long enough for me to take it to baton rouge and get it retuned on the dyno (it has a supercharger) and it started acting up again on my way back home. It was like it was dying unless I would floor it. I pulled over several times and stopped and restarted the car
Eventually it died and I wasn't able to start it at all again. Had it towed back to lafayette once again with the same problem as originally I had. Also sometimes when starting it it would run until I put it in drive then just die on me. Like it didn't have any power at all. The shop has supposedly tested everything from ignition to fuel system, but they think its a pats problem. The computer is brand new, and the pats was supposedly disabled at shop that did the reprogramming. Both shops have yet to find the problem, and I don't know where to go from there. Please help!
It definately sounds like a pats problem because of the lights... except for the "wouldnt run unless i floored it" problem. That sounds like a tuning problem. But, if its a pats problem, it will have a DTC code in the computer, it will say antitheft mismatch key or something similar to that. It very well could be a bad ground or wiring problem from whoever installed the engine

The pats sys identifies your ignition key and then allows the engine to start, instead of disabling it what you should do is get another key made for you jeep by a jeep dealer and let them know that you need the key with the transponder built into it and make sure that you do not by pass the pats system probably that is the whole problem since the vehicle is unable to identify your key it is cutting off thinking that you are stealing your own vehicle!!!!.
