Engine Performance problem
1993 Mercury Villager 6 cyl Two Wheel Drive Automatic 220000 miles
THIS TROUBLE STARTED LATELY, BEEN TO DEALER THEY ARE STUMPPED TOO. CAR HAS NEW FUEL PUMP, CAP, ROTOR, PLUGS. CAR BLOCK HEATER HAS BEEN PLUGGED IN TOO AND STILL HARD TO START, BATTERY GOOD. HAVE TO JUST ABOUT KILL BATTERY BEFORE IT STARTS LIKE IT CRANKS FOR EVER BEFORE IT FINALLY STARTS. AFTER IT STARTS AND WARMS UP IT STARTS WITH VERY LITTLE TROUBLE UNTIL IT COOLS DOWN ABOUT 3 HOURS LATER.I NEVER CHANGED THE IGNITION WIRES BUT WAS TOLD BY MECHANIC THAT OK ANY HELP WOULD BE APPRECIATED.
I would ask them to test the fuel pressure. It might also help to add some gas treatment for cold weather start. I added some " Heet" red bottle and starts like a champ even -25 below. It's suppose to help to remove water and cleans your fuel system also.
