#11 of 12 1996 GMC Jimmy won't stay running HELP by cproulx May 05, 2009 (3:48 am)
I just changed the fuel filter on my Jimmy - it ran fine for 2-3 days. Now it will start and run in park but when I put it into gear and give it gas it sputters hesitates and stalls out. Anyone have any ideas?
#12 of 12 99 JIMMY SLE WARM ENGINE HARD STARTING by puzzledjimmy Aug 09, 2009 (2:48 pm)
I HAVE A 99 JIMMY SLE. IT STARTS UP NORMALLY FIRST THING BUT WHEN IT GETS WARM AND I STOP TO DO SOMETHING FOR ABOUT 15 - 20 MINUTE, IT TAKES A FEW SECONDS TO TURN OVER. I MAY HAVE TO GIVE IT A LITTLE GAS TO TURN IT OVER. IT RUNS GREAT OTHERWISE. I HAVE REPLACED THE GAS TANK,GAS PUMP AND SENDING UNIT. THE FUEL FILTER. THE MAP SENSOR AND AIR FILTER. I HAVE HAD THE SPIDER INJECTORS CHECKED AND THEY ARE FINE. I GET BETWEEN 16 AND 18 MILES TO A GALLON. TOP PERFORMANCE FOR THIS VEHICLE I WAS TOLD. CAN ANYONE TELL ME WHAT MAY BE WRONG?
