2002 Mercury Grand Marquis Electrical Problems

?yrs.ago While backing out of parking space at Calaveras Lumber, after shifting into reverse, & removing my foot from the brake; the engine appeared to receive a huge burst of fuel which shot me backward like a rocket slamming my vehicle into and wedging it under the frame of a pickup truck parked in the same lot. I am glad I was parked and had my foot on the brake prior to this unit or system malfunction otherwise the injuries could easily have been fatal on the highway. I think this defect may be a contributing factor to the car dying recently while on my way to a Wedding Reception in Roseville, which left me stranded after dark for 41/2hrs and 71/2hrs. 2days later. I have not been able to start vehicle since and mechanics unable to diagnose why the engine is fuel starved when system parts tested appear to be in good working order. Something seems to be shutting off power or preventing power to the fuel pump and it is not the inertia switch, relays, fuses etc.. Components have been previously inspected by numerous others including dealer. No Recognizable Alert/Warning Prior to Incidents!

AFTER DRIVING TO MALL MY DAUGHTER REALIZED THAT MY HEAD LIGHTS WERE NOT ON. CHECKED ALL FUSE (UNDER DASH AND UNDER HOOD). NONE WERE BLOWN. REALIZED THAT HAD NO DOME LIGHT BUT DID HAVE MAP/READING LIGHTS. NO TAIL LIGHTS OR BRAKE LIGHTS EXCEPT THIRD BRAKE LIGHTS. HAD BRIGHTS IF I HELD HIGH BEAM LEVER. HAD CAR TOWED TO SHOP. WAS TOLD THAT IT WAS THE LIGHT CONTROL MODULE (LCM). WAS TOLD THAT FORD HAD AND EXTENDED WARRANTY ON THIS PART. TOOK IT TO FORD DEALER. THEY SAID THAT IT WAS ONLY FOR THE 2003-2005 MODELS AND THAT MY CAR WAS NOT COVERED. I THINK THEY SHOULD EXTEND THIS WARRANTY TO THE THE 2002 MODELS SEEING THAT THIS IS A COMMON PROBLEM WITH EARLIER MODELS AND NOT JUST THE 2003-2005 MODELS. IT IS PROBABLY THE SAME PART.

SHORTLY AFTER PURCHASE WE WENT BACK TO DEALER TO COMPLAIN ABOUT BOUNCY SUSPENSION THAT MADE THE CAR GO SIDEWAYS ON THE HIGHWAY WHEN GOING OVER BUMPS WHILE IN MILD TURNS (JUST HIGHWAY DIRECTION CHANGES NOT GETTING OFF/ON, ETC.). DEALER LOOKED INTO PROBLEM VIA FMC AND SAID THE 02 SUSPENSION HAD BEEN CHANGED TO IMPROVE ITS RIDE (HA). THE CHANGES WERE TOO GREAT TO BE ABLE TO CHANGE COMPONENTS TO GET THE RIDE BACK TO WHAT IT WAS IN EARLIER YEARS. ONLY CHANGES WE COULD DO TO IMPROVE IT WERE TO GET 4 NEW HIGH PRESSURE (FAST RESPONDING) KB SHOCKS AND GOODYEAR ASSURANCE TOURING (MORE FLEX IN SIDEWALL) TIRES TO REDUCE THE IMPACT. NOW THE CAR DOES NOT LATERALLY JUMP FEET BUT RATHER INCHES DURING HIGHWAY DRIVING AS DESCRIBED ABOVE. ALSO: STARTING RELAY WAS REPLACED TWICE AND HARNESS CONTACTS IN LOWER STEERING COLUMN DEVELOPED POOR CONNECTIONS AND HAD TO BE SPRAYED WITH HIGH COST CAIG CONTACT IMPROVER TO GET CAR TO START CONSISTENTLY. ALSO: BRAKE PEDAL RAISE/LOWER MOTOR BURNED OUT DUE TO GEAR SEIZING UP IN THAT AREA AND HAD TO BE REPLACED WITH GREAT DIFFICULTY FINDING A REPLACEMENT ACROSS COUNTRY SINCE FMC DOESN'T MAKE PARTS ANYMORE (> 7 YRS I GUESS). ALSO: ALL 8 INDIVIDUAL CYLINDER SPARK COILS WERE REPLACED WITH HIGH PERFORMANCE AFTERMARKET ONES AFTER TWO OF FORDS COILS FAILED, ONE AT A TIME. ALL IN ALL NOT A GREAT CAR. *JS

DT*: THE CONTACT STATED THE VEHICLE DID NOT ALWAYS START. WHEN IT DID START THE ENGINE STALLED WHILE IDLING. TO ALLEVIATE STALLING THE ACCELERATOR PEDAL MUST BE PUMPED HARD WHILE STARTING THE VEHICLE. THE VEHICLE HAS BEEN TO THE DEALERSHIP MULTIPLE TIMES AND THEY WERE UNABLE TO DUPLICATE THE PROBLEM. THE IAC VALVE WAS REPLACED, AND THE COMPUTER WAS REPROGRAMMED. NEITHER OF THESE EFFORTS REPAIRED THE PROBLEM. *AK

PROBLEMS WITH MY WIFE'S 2002 MERCURY GRAND MARQUIS LS NOT CRANKING AT ODD TIMES. I HAVE CRANKED UP THE CAR, AND DRIVEN IT INTO THE GARAGE, THEN GO BACK OUT A COUPLE MINUTE LATER - 15-30 MINUTES - AND THE CAR WOULD NOT CRANK. THE LAST TIME I PULLED THE CAR INTO THE GARAGE ONE EVENING AND WHEN MY WIFE WENT TO GO TO WORK THE NEXT MORNING IT WOULD NOT CRANK. THE DEALER'S SERVICE DEPARTMENT CAN NOT FIND A PROBLEM. HOWEVER, THE LEFT TURN SIGNAL WENT OUT ABOUT A YEAR AGO, REQUIRING A MODULE BE REPLACED. AFTER THAT WE NOTICED THE FOOT PEDAL ADJUSTMENT DIID NOT WORK AND A LOOSE CONNECTION WAS FOUND TO BE THE PROBLEM. THE STARTING PROBLEMS DID NOT START UNTIL AFTER THE TURN SIGNAL MODULE WAS REPLACED. I HAVE FOUND OTHER INCIDENTS OF PROBLEMS WITH THE IGNITION SWITCH FOR THIS MODEL MERCURY. *AK

THIS IS A CONCERN AND I AM WONDERING, IF IT SHOULD IN FACT BE A COMPLAINT. I PURCHASED A 2002 MERCURY MARQUIS ON JUNE 12TH OF 2003. I WAS ASSURED THIS, AS OTHER AUTOS HAD BEEN CHECKED OUT AND IN GOOD ORDER. I AM NOW NOTICING THE IGNITION KEY SOMETIMES DOES NOT TURN WHEN I AM TRYING TO START THE CAR. EQUALLY IMPORTANT, I RAN A CARFAX REPORT AND DISCOVERED ON 11/18/02 THIS CAR HAD 27,262 MILES. WHEN I PURCHASED IT, AND BECAUSE OF THE MILEAGE, WHICH AT THAT TIME WAS 27,279 I WAS ASSURED THIS WAS A GOOD CAR. I FIND NOW, THAT IT WAS NOT THE RETIRED, SENIOR CITIZEN WHO WANTED A NEW AUTO TRADE IN, BUT THIS WAS A RENTAL CAR FROM BURLINGGAME, CA. NOW I AM WONDERING IF I SHOULD BE CONCERNED THIS CAR WAS SITTING FOR 8 MONTHS AND THUS ONLY HAD 17 MILES MORE IN JUNE THAN IN NOVEMBER? OR BE SUSPECT ABOUT THE ODOMETER BEING ROLLED BACK? IT JUST DOESN'T SEEM ACCURATE A 2002 WOULD ONLY HAVE 17 MILES MORE IN 8 MONTHS FROM NOV. 2002 TO JUNE 12, 2003.THANK YOU.
