#41 of 326 2001 Chevy Blazer wont start by delk1977 Dec 20, 2006 (12:24 pm)
In October I bought a 2001 Chevy Blazer LS from a used car lot locally. Shortly after I purchased the vehicle I stopped at convenience store and turned the truck off. Upon returning the truck would not start. It would turn over fine but not start. I waited about 10 minutes and it started again. Then a couple weeks later I drove the vehicle from New York to Virginia. Once at my time share in VA I turned the truck off and a few minutes later the same thing, it wouldn’t start. I called the dealership and was told to disconnect the battery let it sit for a few moments and retry as it was a notorious problem with the anti-theft system. I did so, however, it did not immediately start. After about 20 minutes of sitting it did start.   Since October I have had no problems with the vehicle until December 18th. I went outside in the morning and attempted to start the truck and like before, it wouldn’t start. It turned over ok but would not ignite. After waiting still no joy. I had the vehicle towed to the dealerships garage and was told it was the fuel pump and would cost $425.00 to repair.   My issue is when I bought the truck it had the 60 day warrantee. I informed the dealer of this problem during the warrantee and was told it was a notorious problem with the anti-theft system and not to worry just to let it sit and it would start again. I told them this was the same problem as before and was told it wasn’t the fuel pump before because fuel pumps just don’t stop working then start working again.   I called a reputable Chevy dealership and was told the anti-theft system would not allow the truck to turn over and that furthermore it was possible for the fuel pump to malfunction and then begin functioning again.   My questions are... 1. Do you think it was indeed the fuel pump that was prohibiting the truck from starting? 2. Is it indeed possible for the pump to malfunction and then begin functioning again?   I am paying for the repairs however; I intend to file a complaint with the NYS Attorney General regarding my warrantee not covering the repairs. Any insight anyone could give would be appreciated. Replies to this message: cpuhach (Nov 28, 2007 5:52 pm) ejm3905 (Dec 13, 2007 11:05 am) fixit8 (Apr 11, 2009 11:22 am)

Replying to: jtheif (Jan 13, 2007 10:43 am) When you turn the key to the spring loaded start position is 12v getting to the starter solenoid from the ign wire (samll one)? I've seen that nut get loose cause a pain to tighten up there.

#47 of 326 01 Blazer Stalling by captain67 Jan 15, 2007 (4:59 am)
This 01 Blazer has a 4.3 ltr V-6, 150000 miles. It had been running just fine when one day I tried to start the vehicle and all it did was turn over and over. I put some fuel down the throttle body and it started and ran momentarily. I waited about a half hour and just for the hell of it I tried to start and vehicle again and it started and ran for two months without another incident.    Once again 2 months later the same problem occurred and this time I took it to a dealer and they replaced the mass air flow sensor, fuel filter and fuel pump. Vehicle ran fine for 1 month but Friday, every time I stopped at a stop sign or tried to slow down to make a turn, the engine would stall. I would crank it over and over and it would start again but as I tried to get it back to the dealer the engine was starting harder each time ( meaning it would turn over and over more before it would start).   About 6 miles from the dealer, the engine stalled and would not start again. After about 20 minutes went by for some reason it fired up and has been running fine ever since.   The dealer put their Tech 2 code reader on it and there was a code shown something about a loss of communication from the BCM but it had rechecked and passed sometime during the last 20 miles of driving. I have no service engine light on at the present time. Is my computer going bad? Does anyone have any ideas? Replies to this message: repairdog (Jan 15, 2007 5:15 am)

Replying to: captain67 (Jan 15, 2007 4:59 am) Perhaps its the security system called Passlock that cuts fuel thinking someone is stealing it. BCM controlled and GM has the bulletin on the failure modes - usually a bad connector from the main wiring in the column. Does the security light come on when this happens - if so thats it. When it will not start does the security light stay on (should go out after apprx 5 sec when you turn to run).
#49 of 326 01 Blazer Stallling by captain67 Jan 15, 2007 (5:32 am)
Ever since we purchased this vehicle, the security light has been intermitent. It comes on and goes off at will, usually when we are driving down the road. Would this connector cause the vehicle to stall when slowing down or stopping?
#50 of 326 01 Blazer Stallling by captain67 Jan 15, 2007 (5:36 am)
If so what connecter am I looking for? Is this a part I can purchase somewhere or do I need to pull one from a junker? Replies to this message: crummydo (Jan 15, 2007 8:19 am) repairdog (Jan 16, 2007 2:45 am) repairdog (Jan 16, 2007 2:56 am) preludeboy1 (Jan 17, 2007 2:30 pm)
