FUEL PUMP ISSUE ?

10

Asked by Mar 16, 2008 at 09:02 AM about the 1994 Chevrolet C/K 1500

Question type: Maintenance & Repair

MY 94 CHEVY RUNS GREAT IN ALL CONDITIONS EXEPT WHEN I AM PULLING A LONG HILL. USUALLY ABOUT HALF WAY UP THE HILL ON THE INTERSTATE (RUNNING BETWEEN 55 - 70 MPH) THE ENGINE WILL SORT OF MISS, KINDA OF A SPITTING SPUTERING SOUND. I CAN FEEL THE TRUCK SLIGHTLY JERKING.
HERE IS THE INTERESTING PART. ALL I HAVE TO DO TO MAKE IT STOP IS TO ACCELERATE. EVEN THE SLIGHTEST AMOUNT OF ACCELERATION AND THE TRUCK SMOOTHS OUT. ITS FINE WHEN I'M ON FLAT LAND, BUT IF I'M PULLING A HILL AT A CONSTANT SPEED, I'LL GET THE JERKING.
NEW TRANSMITION A YEAR AGO DIDN'T HAVE ANY AFFECT ON PROBLEM.TRUCK HAS 176,000 MILES ON IT.
THE ONLY THING I WONDER ABOUT IS, ABOUT 3 YEARS AGO I RAN OUT OF GAS AND HAD TO HAVE A NEW FUEL PUMP INSTALLED. I'M NOT SURE IF THE PUMP WAS OEM OR NOT.
ANY IDEAS ?    THANKS, BILL

You can short out this kind of minor issue by taking help of manual if u have otherwise must buy for save your time,In fact, im working at a car-garage, repairing cars and motorcycles all day long. I got all the manuals i needed from www.carmanualstore.com! Check it out - they have the best quality manuals for cheapest price in my opinion. I use it everytime, when im confronted with a problem, where i need some help.

Check the throttle shaft on the fuel injection throttle body for two much play,it can cause a vacuum leak & would need to be replaced or rebushed. Have You done a complete tuneup recently?
