When driveing the car after a little while it starts to die the lights start dimming and the radios goes all static and then it stops then i get a jumpstart and it goes again and dies again i have replaced the battery and the alternator and it still does this i was also told by a garage that there is no power getting to the fuel pump fuse and a while back i had to replace the fuel pump about a year ago when it sits for a while it starts up with key but if i drive it and then get to where i am going and i shut it off and then come out from the store it wont start up unless it gets a jumpstart
Re: When driveing the car after a little while it starts...
You have a very bad electrical problem. what ever it is draining the battery faster than the alternator can charge it . ..i dont understand no power to fuel pump but car will run

I assume there's a problem with alternator. Check the grounding to engine, check continuity of a positive wire between alternator and battery. the energizing voltage should be checked as well. Might be the bad connection between battery and vehicle body grounding. Diesel cars are sensitive even in a little loss of connection and rust in the connection points.
Sounds like a bad connection somewhere. Maybe the thieves or the repair shop damaged/loosened something. I would start the car and start wiggling/moving wires and connections to try to narrow down where the problem is. Start at the alternator connections, both at the alternator and where the thick wire connects, probably at the power distribution box but it may go straight to the battery; don't recall on that car.
If the batt light is on, the alternator is not charging the battery. If the battery won't hold a charge, it could be failing. If you are having a specific problem with your PT Cruiser or Mustang, let us know what it is.
If all your connections are clean and sound, then your car should be able to run without a battery. Start the car and disconnect the negative terminal. If it stops your alternator is faulty. This would explain dim lights that are draining the life out of the battery instead of being alternator driven. Same as the dieing while driving, the battery can't keep supplying power forever without being recharged by the alternator.
If the alternator is ok, the battery needs replacing. Repeated draining of batteries kills them.
