1995 Chevrolet C3500

I HAVE A 1995 3500 DULLY 6.5 TURBO, ENG F, SERIAL # [XXX]. I BOUGHT IT 4 YEARS AGO 170,000 MILES. THIS TRUCK IS USED FOR TOWING AND HAULING HEAVY LOADS IN MY BUSINESS.. ONE MONTH AFTER I BOUGHT IT AND AFTER SEVERAL STALLS (CREATING SOME CLOSE CALLS) AND HARD STARTING AND AFTER SEVERAL ATTEMPTS AT FIXING STALLING, STARTING PROBLEM I LEARNED OF THE PMD PROBLEM. I REPLACEMENT AND RELOCATED PMD WITH STANADYNE PART # 34583, AND RELOCATED TO FIREWALL. AFTER DRIVING A FEW MONTHS STARTED EXPERIENCING SOME HARD STARTING AND STALLING AGAIN. THIS SUMMER 2010 WHEN TEMPERATURES REACHED THE 90S IT GOT REALLY BAD. ONCE DYEING ON A RIGHT HAND DOWNHILL CURVE THAT CAUSED THE TRUCK TO CROSS THE CENTER LINE FORCING AN ON COMING CAR TO TAKE EVASIVE ACTION TO AVOID A HEAD ON COLLISION BEFORE I GOT IT UNDER CONTROL. I HOPE YOU NEVER HAVE TO EXPERIENCE CONTROLLING A CHEVROLET 3500 DULLY WITHOUT POWER GOING DOWN A HILL USING EXTREME EFFORTS TO STEER AND STOP. AND I HOPE YOU NEVER MEET ONE IN LIKE CONDITION HEADING IN YOUR DIRECTION. A VERY FRIGHTENING EXPERIENCE. IT STALLED AGAIN ON A CURVING UPHILL ROAD WITH NO SHOULDERS WITH A TRAILER IN TOW, CREATING A HAZARD DUE TO BLIND CURVES BEHIND TRUCK AND HAVING TO LET ROLL BACK DOWN HILL IN ORDER TO GET IT OFF ROAD AND WAIT FOR IT TO COOL DOWN BEFORE IT WOULD RESTART. REPLACED PMD AGAIN, THIS TIME WITH NEW PART STANADYNE # 35976 AND RELOCATING TO BEHIND FRONT BUMPER. NOW TRUCK HAS STARTED EXPERIENCING A HARD START UNTIL COOLS DOWN CONDITION AGAIN. I AM FORCED TO CONTINUE USING THIS TRUCK AGAINST MY BETTER JUDGMENT BECAUSE OF ECONOMIC CONDITIONS AND MY BUSINESS. I HAVE MADE MY WIFE AND OTHER AWARE OF THIS STALLING, STARTING CONDITION SO THAT IF I DO HAVE AN ACCIDENT THEY CAN HAVE THE PROPER INVESTIGATION DONE. CAN YOU IMAGINE HOW MANY OF THESE HEAVY LOADED TRUCKS ARE STILL COMING DOWN THE ROAD TOWARD YOUR FAMILIES? THEY ARE TICKING BOMBS WAITING TO KILL SOMEONE INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
