FUEL/PROPULSION SYSTEM
I AM HEAVILY CONCERNED WITH THE MAJOR SAFETY ISSUES OF MY BELOVED MAZDA AND NEED YOUR HELP. MY SEAT BELT RETRACTORS ARE BROKEN (EMERGENCY), THE HORNS DO NOT WORK (EMERGENCY), MY REAR WINDSHIELD WIPER AND FLUIDS DO NOT WORK (VISIBILITY), MY BRAKE LIGHT IS ON(EMERGENCY), AND MY PULSATION DAMPER IS LEAKING FUEL (FIRE HAZARD). I HAVE READ MANY STORIES ABOUT RX7'S THAT WOULD CATCH ON FIRE DUE TO THE FUEL PULSATION DAMPERS LEAKING FUEL ONTO THE ENGINE, EVENTUALLY IGNITING THEIR WHOLE CAR TO ASHES.

FUEL SYSTEM, GASOLINE
MAZDA'S RX-7 MODEL FC3S FROM MODEL YEAR 1986-1992'S FUEL PULSATION DAMPER HAS AN ISSUE THAT IT WILL LEAK, SINCE THE DEVICE SITS ON TOP OF THE ENGINE SO IF THE TIMING IS RIGHT, AN ENGINE FIRE WILL START. IT IS A VERY WELL KNOWN ISSUE IN THE RX-7 COMMUNITY. IM SURPRISED NO ONE EVER FILED A COMPLAIN OVER THIS. 1986-1988'S FUEL PULSATION DAMPER IS VERY PRONE TO THIS DEFECT, THEY CHANGED THE DESIGN AND USE THEM ON LATER MODEL YEAR OF RX-7 FROM 1989-1992, BUT IT WILL STILL LEAK.

MAZDA 1994 RX7 FD3S PULSATION DAMPENER FAILURE. CAUSED LOSS OF FUEL AND DAMAGE TO WIRE HARNESS. THE FUEL LEAKED ONTO AND INTO THE WIRE HARNESS AND CAUSED THE HARNESS TO BECOME SATURATED, DAMP AND BRITTLE. I ALSO HAD TO PAY TO REPLACE AND INSTALL NEW PULSATION DAMPENER, WIRE HARNESS, INTAKE GASKET AND A FEW OTHER PARTS DO TO THE PULSATION DAMPENER FAILURE. I ALSO HAD TO PAY FOR LABOR.

FUEL SYSTEM, GASOLINE:FUEL INJECTION SYSTEM:FUEL RAIL
UNDER NORMAL DRIVING CONDITIONS, THE PULSATION DAMENER ON THE PRIMARY FUEL RAIL FAILED, SPRAYING FUEL OVER THE ENTIRE ENGINE BAY, WHICH RESULTED IN A FIRE OF THE COMPARTMENT, WHICH WAS QUICKLY EXTINGUISHED VIA HANDHELD FIRE EXTINGUISHER. THE PART WAS REPLACED, AT A HIGH COST, DUE TO THE FACT THAT THE WHOLE FUEL RAIL MUST BE REPLACED TO CORRECT THE PROBLEM.

FUEL SYSTEM, GASOLINE:DELIVERY
I NOTICED WHITE SMOKE COMING INTO THE CAR WHILE DRIVING TO WORK. I STOPPED THE CAR RIGHT AWAY AND OPENED THE HOOD TO SEE THE BACK OF THE ENGINE ON FIRE. I PUT THE FIRE OUT WITH A FIRE EXTINGUISHER AND HAD THE CAR TOWED TO A MAZDA ROTARY ENGINE SPECIALIST. I WAS INFORMED BY THE MECHANIC THAT THE FIRE WAS A RESULT OF THE FAULTY FACTORY FUEL LINE AND THE FUEL INJECTION SYSTEM, WHICH ARE A WELL KNOWN PROBLEM BY MAZDA MECHANICS. THE MECHANIC TOLD ME THAT THESE FIRES HAPPEN QUITE FREQUENTLY IN 1993-1996 RX-7'S AS WELL AS IN THE PRIOR BODY STYLE. I COULD HAVE BEEN SERIOUSLY INJURED FROM THIS INCIDENT, AND MY CAR NOW NEEDS OVER $3,000 WORTH OF REPAIRS, ALL DUE TO A KNOWN PROBLEM THAT HAS NEVER BEEN RECALLED. PLEASE HELP ME. DT

PUSATION DAMPNER ON PRIMARY FUEL DELIVERY RAIL DIAPHRAM FAILURE. GASOLINE LEAKAGE IN LARGE QUANTITIES RIGHT ABOVE HOT ENGINE. VERY SERIOUS FIRE HAZARD..

I CAME EXTREMELY CLOSE TO AN ENGINE FIRE. MY ENGINE BAY WAS SOAKED WITH FUEL. NOW HALF THE ENGINE HAS TO BE TAKEN OUT IN ORDER TO FIX THIS PROBLEM. I SHOULDNT HAVE TO FIX THIS.

WHY IS THIS NOT ON THE FUEL SYSTEM RECALL FIX LIST. IT IS KNOW TO FAIL.
