| I have a 03 GMC Safari. When I try to start it it acts as though it is flooded and won't start? There is fuel and the pump is working. Help | |

Here is my story. About 2 years ago my 2000 Safari started having all the problems described in the previous post here. Error code p300 random misfires. Engine would act up when it was wet out rain and snow. After a complete tuneup wires,cap,rotor,sparks fuel filter and a complete check of the fuel system and injectors it left my mechanic scratching his head. Now for the clincher at the same time the engine problems started my turn signal switch started to act flakey the left momentary turn signal stopped working and when it was wet and cold the turn signal would work on and off depending on the weather conditions. In my mind it was time to trade my van in and be done with it. But I love this van and did not want to part with it. So I started thinking could it be the turn signal switch causing a short to cars circuitry when it is wet out causing the misfires. Would my mechanic think I was a total moron if I told him my theory. Well I bought a new switch assembly cheap and had my mechanic put it in not telling him about my theory or telling him I was still having engine misfire problems. Well it has been a year now without any engine problems in any kind of weather. Runs like a champ. Who would of thought! |

| My 1993 GMC Safari has been sitting in the driveway unused for about a week. Before this it ran just fine. When I tried to start it the alarm went off and the engine wouldn't start. The batteries for the remote door lock switch had run out, so I replaced them thinking I could disarm the alarm. No such luck. Tried to start it again, alarm went off. Now nothing works - no lights, power door switches won't work, the alarm light has gone off, etc. Thought it might be the battery (which is new, by the way.) Tried to jump it to no avail. Is it possible that the security system somehow disabled something preventing the engine from starting? If so, what do I do to bypass it? I bought this vehicle used about a month ago, so there's no user's manual. I love my truck (van) and want to drive it. Can anyone help? | |

Replying to: keico (Mar 18, 2009 2:56 pm) 9 months after I rebuild the fuel pump, it just died. Was parked in front of real estate office paying rent, and that was all she wrote. She cut off and I knew it was the fuel pump Had it towed to the house. Could not here the pump when you turn key on. I verified the pump was getting voltage. Why oh why so many problems I hear about these van with bad fuel pumps Well anyway ordered the entire assembly. later will order another one for backup. Lets see what happens |
