MECHANIC NEEDED MOPAR MUSCLE CAR

WE HAVE A 73 CHALLENGER, WHEN CRANKING OVER THE ENGINE, AND WHEN RELEASING FROM THE STARTER POSITION, THE ENGINE STILL CRANKS OVER UNTIL THE BATTERY CABLE IS REMOVED. IT HAS BLEW THE FUSE ABLE LINK AT THE JUNCTION BOX WHICH IS ATTACHED AT THE FENDER WELL ON THE DRIVER SIDE. COULD BE THE STARTER RELAY NEEDS TO BE REPLACED, BUT THAT DOESN'T EXPLAIN WHY THE FUSE BLEW IN THE FIRST PLACE.

ALSO WHEN THE CAR IS PUT IN GEAR THE ENGINE WANTS TO DIE OUT. THE TIMING IS SET AT 12 DEGREES ADVANCE. IT HAS A ELECTRIC FUEL PUMP THAT IS RATED 5.5 - 9.5 LBS OF PRESSURE WHICH SEEMS TO BE WORKING FINE.

LOOKING FOR SOMEONE THAT IS KNOWLEDGEABLE, ELECTRICAL AND HAS EXPERIENCE WORKING ON MOPAR MUSCLE CARS.

THANKS FOR YOUR HELP. David.
