1995 Chevrolet K2500

TRUCK WITH 6.5 TURBO DIESEL WOULD SPORADICALLY HICCUP AND STALL WHILE DRIVING DOWN THE ROAD CAUSING LOSS OF POWER TO OPERATE STEERING AND BRAKES PROPERLY, PUT TRUCK IN NEUTRAL AND ATTEMPT TO RESTART, SOMETIMES IT WOULDN'T FOR SEVERAL MINUTES, OTHER TIMES IT WOULD, REGAINING CONTROL OF THE VEHICLES POWER STEERING AND BRAKES. ON SEVERAL OCCASIONS WHILE DRIVING THE VEHICLE WOULD HICCUP THEN START ACCELERATING ON IT'S OWN WITH NO WAY TO REGAIN CONTROL WITHOUT TURNING OFF THE IGNITION AND COASTING TO A STOP. SOMETIMES I WOULD NEED TO TRY RESTARTING IT SEVERAL TIMES BECAUSE THE ENGINE WOULD RACE OUT OF CONTROL. I HAVE HAD THE FUEL INJECTION PUMP REPLACED AND SEVERAL PUMP MOUNTED DRIVER MODULES "PMD'S" FROM BOTH STANADYNE AND D TECH WHICH GM HAD AUTHORIZED TO MAKE THESE PARTS FOR THEM. I ALSO HAVE A 1998 CHEVY K3500 WITH THE 6.5 TURBO DIESEL THAT HAS HAD THE SAME PROBLEMS NUMEROUS TIMES. *TR

MY 1995 SILVERADO WITH THE 6.5 TURBO SEEMS TO BE HAVE PROBLEMS WITH THE PMD OTHERWISE KNOWN AS THE FSD. THE VEHICLE HAS STALLED GOING DOWN THE FREEWAY ONCE TODAY AND 3 OTHER TIMES, AND STALLED WHILE IN TOWN DRIVING 4 TIMES ALL IN THE LAST 2 WEEKS. STALLING ON THE FREEWAY IS NOT ACCEPTABLE AS HAS PROVEN VERY SCARY. AS THESE TRUCKS DO NOT STEER WELL WITH NO POWER. NOR DO THE BRAKES WORK WELL WHILE IN A STALL. TONIGHT IT WOULD NOT START WHILE AT A BUSINESS. I HAD TO SIT FOR 45 MINUTES WAITING ON A TOW TRUCK. ONLY TO HAVE THE TRUCK START ONCE THE TOW TRUCK ARRIVED. THE FSD APPEARS TO BE THE PROBLEM. MY VEHICLE HAS 107,030K MILES ON IT. THIS IS A KNOWN PROBLEM WITH GM DIESEL PICKUPS. WHY HASN'T GM REPAIRED OR RECALLED THIS BAD DESIGN? I HAVE BEEN READING VARIOUS CHAT ROOM BOARDS TONIGHT FINDING THIS IS A BAD PROBLEM THAT HAS BEEN AROUND FOR SOME TIME. *CB

THE FUEL PUMP HAS GONE OUT 4 TIMES IN 125,000 MILES. EVERY DEALER KNOWS WHAT THE PROBLEM IS AND SAYS THEY REPLACE THIS MORETHAN ANYTHING ELSE. OTHER PEOPLE I KNOW CARRY SPARE FUEL PUMPS. IT MUST BE A VERY COMMON PROBLEM, AND I GET THE SAME PUMP WITH NO CHANGES EACK TIME. I THINK SOME PRODUCT IMPROVEMENT IS IN ORDER. CAN YOU TELL WHAT ELSE I NEED TO DO.*AK
