1998 Chevrolet Silverado 3500

I WAS DRIVING MY ~ CHEVY DUALLY DIESEL TRUCK ~ ON A FREEWAY PULLING A TRAILER WITH MY ANTIQUE CAR IN IT WHEN THE TRUCK KIND OF HESITATED / SPUTTERED AND DIED ! I LOST POWER BRAKES - BUT WAS ABLE TO GET PULLED OVER TO SIDE AND AFTER A PERIOD OF TIME THE TRUCK RESTARTED ... NUMEROUS TIMES AFTER THIS I HAD THE TRUCK DIE AND HESITATE - I TOOK TO A CHEVROLET DEALER ONCE - THEY QUESTIONED THE PASSLOCK SECURITY SYSTEM AND BAD IGNITION SWITCH - WANTED A RIDICULOUS PRICE TO FIX .... THE TRUCK ONLY HAD 73,000 MILES WHEN I BOUGHT IT , AND I HAVE NOT DRIVEN IT MUCH ONLY 81,000 MILES PRESENTLY - AND I HAVE NOT DRIVEN IT IN OVER A YEAR BECAUSE OF FAILURES TO START. I HAD BOUGHT A KIT AND "PMD / FSD" MODULES AND FINALLY GOT AROUND TO SWAPPING IN ANOTHER ONE - AND WOW NOW THE TRUCK IS RUNNING ----------------- " IT WAS A BAD STANADYNE PMD " ! I HAVE READ ON THE INTERNET NOW THE TROUBLES THESE HAVE HAD DUE TO HEAT AND WHERE PART HAS BEEN MOUNTED IN THE ENGINE AREA. I WAS AN ELECTRONIC INSTRUCTOR IN THE TECHNICAL COLLEGE SYSTEMS AND AS I NOW LOOK AT / EVALUATE THIS PART MADE BY STANADYNE ==== TO ME ITS DESIGN / CONSTRUCTION LOOKS AS IF ITS BUILT TO HOLD THE HEAT IT DEVELOPS INSIDE OF THE PLASTIC INSULATED CASE - THEREBY NOT RELEASING HEAT TO THE OUTSIDE CAUSING ITS ULTIMATE FAILURE DUE TO INTERNAL HEAT BUILDUP . *TR

98 CHEV K3500 WITH 6.5 TURBO DIESEL WOULD STALL AT HIGHWAY SPEEDS CAUSING LOSS OF POWER STEERING AND POWER BRAKES. ENGINE SOMETIMES WOULD RESTART WHEN VEHICLE PUT IN NEUTRAL OTHER TIMES IT MAY TAKE SVERAL MINUTES. ON SEVERAL OCCASIONS THE ENGINE WOULD HICKUP THEN BEGIN TO ACCELERATE ON IT'S OWN DESPITE REMOVING MY FOOT FROM THE PEDAL. I WOULD HAVE TO TURN THE IGNITION OFF TO SLOW THE VEHICLE AND REGAIN CONTROL. SOMETIMES WHEN ATTEMPTING TO RESTART ENGINE IT WOULD EITHER OVER REV OR THE RPM'S WOULD SURGE UP AND DOWN SEVERELY. ON ONE OCCASION, AS I SLOWED TO STOP AT A SIGN BEFORE PULLING OUT ONTO A 4 LANE ROAD THE VEHICLE SUDDENLY ACCELERATED ON IT'S OWN LAUNCHING ME OUT INTO THE ROAD NARROWLY MISSING ON COMING TRAFFIC. ANOTHER TIME WHILE PULLING INTO A PARKING SPOT AT MY BANK, THE VEHICLE SUDDENLY ACCELERATED, JUMPING THE CURB AND GOING INTO THE BUSHES ON THE LAWN! I HAVE HAD THIS TRUCK INTO NUMEROUS GM DEALERSHIPS AND INDEPENDENT REPAIR SHOPS AND HAD THE FUEL INJECTION PUMP REPLACED AND NUMEROUS PUMP DRIVER MODULES, PMD'S MADE FOR GM BY EITHER STANADYNE AND D TECH AND HAD THEM MOUNTED ON A REMOTE HEAT SINK FOR COOLER OPERATING TEMPS. THIS IS A SEVERELY DANGEROUS SITUATION WHICH CAUSES LOSS OF CONTROL OF THE VEHICLE AND POTENTIAL CRASHES! I HAVE EXPERIENCED THIS ISSUE WITH 2 DIFFERENT GM VEHICLES I OWN WITH THE 6.5 TURBO DIESEL ENGINE. *TR

MY TRUCK IS A 98 CHEVY K3500. I BOUGHT IT USED FROM SOMEONE THAT SAID IT WAS USED AT THE SMITHSONIAN. WHEN I FIRST GOT IT NEEDED EVERYTHING REPLACED ON THE FUEL SYSTEM. THEN LAST YEAR ONE OF MY BRAKE LINES SNAPPED AND HAD TO REPLACE IT AND NOW TODAY THE OTHER ONE SNAPPED. SOMEONE NEEDS TO DO SOMETHING ABOUT THIS PROBLEM BEFORE SOMEONE IS KILLED. THIS IS A HD TRUCK AND GOD FORBID I WAS ON A MAIN ROAD AND NOT IN MY DRIVEWAY.

UPDATED 09/28/10 *BF THE CONSUEMR STATED IT WAS THE BOX CONNECTED TO THE FUEL INJECTOR, BUT THE DEALER STATED IT WAS THE FUEL INJECTOR AND REPLACED IT. UPDATED 10/01/10

SEVERAL TIMES THE TRUCK WHILE STOPPED AT AN INTERSECTION HAS ACCELERATED ON IT'S OWN AND PULLED ME INTO AN INTERSECTION. SEVERAL TIMES WHILE DRIVING DOWN THE ROAD AT 40 - 45 MPH THE TRUCK HAS ACCELERATED ON IT'S OWN TO OVER 70 MPH ON BACK COUNTY ROADS BEFORE I SHUT IT OFF AND COAST TO A STOP. UPON TRYING TO RESTART ENGINE IT WOULD REV UP TO 4000 RPM THEN FLUCTUATE FROM 1000 - 3000 RPM. AFTER SEVERAL RESTARTS IT WOULD RUN NORMALLY UNTIL THE NEXT OCCURRENCE. ONCE WHILE PULLING INTO A BANK PARKING SPACE THE TRUCK SUDDENLY ACCELERATED, BEFORE I WAS ABLE TO SHUT IT OFF IT JUMPED THE CURB AND WENT INTO THE SHRUBS. THIS PROBLEM HAS OCCURRED SEVERAL TIMES IN A 2 WEEK PERIOD BEGINNING LATE IN MARCH 2010. IT SEEMS VERY SIMILAR TO PROBLEMS ENCOUNTERED BY TOYOTA VEHICLES! *TR
