Replying to: bummer72 (Jun 26, 2005 2:48 pm) Just quickly looking at the electrical schematics. Start by checking all the fuses in the underhood dist. box. It appears the electrical all goes through the ECM. I will keep looking though to narrow it down. Replies to this message: bummer72 (Jun 27, 2005 1:14 pm) baytex (Jul 07, 2005 5:44 pm)

#941 of 1889 Electrical issue: by 97gmcsafari Jun 27, 2005 (10:42 pm)
I went to start my '97 GMC Safari Van tonight... NOTHING. Charged the battery, hooked it back up, and all my outside lights (parking & headlights) are on and the buzzer is making noise inside, but THE LIGHT SWITCH IS OFF. If I turn the dimmer switch all the way down, the buzzer goes away but the lights are still on everywhere inside & out. Something TOTALLY drained my battery last night, not sure what went wrong, everything was working fine until now. WHAT COULD THE CAUSES BE??? Thanks in advance!

#943 of 1889 Safari will not always start by gaulais Jun 28, 2005 (4:30 pm)
When my 2Safari 2000 90K miles do not want to start, I then disconnect the Air Flow Meter electrical connection, and after that it will fire up like a new one. I recconect the module after and here I go. Oops not really. When I'm drivig at any speed, sometime put not always, the engine will shut down for a fraction of a second and restart. The fuel pump look ok to me + the air filter is new... And since yesterday it sometime stall when I stop at a light or at a stop sign. My dealer does not have a clue on what going on since the computer does not give any code or light and because the problems occurs"> accasionnaly. Any body can help ?

Replying to: gaulais (Jun 28, 2005 4:30 pm) My mechanic told me that fuel pump malfunction would not register a code. When My '98's fuel pump failed just barely out of warranty, it stalled intermittently like yours. You can try knocking on the side of the fuel tank with a mallet next time it stalls. If it starts again, you can zero in on the fuel pump and do more testing. BTW, a plugged fuel filter will have similar symptom too.

Replying to: gaulais (Jun 28, 2005 4:30 pm) Wow! You are having exactly the same symptoms as my 2000 Astro with 96,000kms. Same stories from my favorite shop and also the Dealer. I have now spent $400 on a tune-up replacing plugs, fuel filter, air filter, distributor cap, and rotor. No improvement!! Plus $200 diagnosing the problem with the same results. Suspect it is the fuel pump too. I just hope it will fail one of these days so I know for sure! It is expensive to pull the tank and replace the pump on a guess! It just ran for a whole week with no problem and then started acting up again yesterday! Let me know if you have ny success solving your problem!

Replying to: steve34 (Jun 30, 2005 11:10 am) Yesterday I install a fuel pressure gauge and it will sit on the floor of the van has long that it will take. Right now the fuel pump is working perfectly up to 60 psi during priming time; 52 - 54 at idle; and up to 60 when cruising. Now I'm just waiting for the van to go crazy and see if it is really the fuel pump. Honnestly I not so sure because of the unrelated link be twin the disconnection of the air flow control meter and the fuel pump when it wont start.
