Defective fuse#8, PCM connector melted and PCM blown
2005 Ford Escapr XLT 3.0L 6 cylinder engine. Was stopped at a red light, when light changed I accelerated and car cut out. Would not re-start. No engine or warning lights prior - just died. Pushed it to a mechanic shop (lucky there was one on the corner of the intersection where the car died). Mechanic checked it and replaced the fuse, which then blew. He says a defective fuse #8 melted the PCM connector and shorted the PCM. If we replace the fuse, the PCM and the PCM connector what, if anything, can be done to prevent this from happening again? What would make the fuse defective/fail like this? Thanks for the time you all give to help people out!

You must find the short in your wiring or else they will keep pulling fuses and causing more electrical issues what's backtrack on an electrical schematic for your vehicle where these components wearing begin and end. With a multimeter you can test 4 shorts and continuity Legend of your wiring that you suspect to be culprit of your situation. Replace the wiring and or fuses connectors or what have you and you should be fine
It depends on what the fuse controls. No sense in replacing PCM if root cause for fuse blowing is not found.
Thanks, this is what I was thinking too. From what I can find online, Fuse#8 is the fuse for the PCM, injectors and coil.
A possibility is that the PCM CONNECTOR WAS LOOSE AND WATER WAS ABLE TO ENTER IT IF IT IS UNDER THE HOOD DID IT RAIN RECENTLY OR A CAR WASH? also are you the original owner of the vehicle if no IT MIGHT HAVE BEEN IN AN ACCIDENT AND BODY SHOP GUYS DRILLED HOLES IN THE FENDER TO PULL OUT DENTS AND COULD HAVE DRILLED INTO THE WIRING HARNESS EXPOSING WIRES +TO THE BODY - OR AT THE POWER DISTRIBUTION BOX ALSO THERE IS A JUNCTION CONNECTOR THAT BRINGS POWER INTO THE PASSENGER COMPARTMENT FUSE BOX FROM UNDER THE HOOD THESE ARE THE ONLY THINGS I CAN THINK OF TO CAUSE THIS TO HAPPEN THE CAR NEEDS TO GO TO AN ELECTRICAL SHOP TO FIND OUT WHAT HAPPENED AND FIX IT BUT $$$$$$$ IS COMING SORRY FOR YOU BUT ON THE BRIGHT SIDE EVERYONE WANTS TO BE CRUISING WITH SUSAN GOOD LUCK STEPHEN
Usual suspect is corrosion, i use Dielectric grease on all my plugs on my vehicle to keep moisture out of connections, i also use battery spray on terminal sealer on battery, starter, ground connections
not so much on pcm side as to the wires on the plugs,plus i would be checking wiring for wires rubbing and grounding out
MAKE A STINK! U ARE NOT ALONE. Please talk to ur doctor. If they don't listen, talk to ur mla, if they don't listen talk to ur radio station/local media outlet. There has been recalls on faulty medical implants. If u have info on device, Google it. U might b able to partake in a class action. Serious stuff dude! Look into it. CBC has done a series on it. It is real! Please do yourself a favour and don't b quiet!
