won't start

  1. Electrical Issue

    General
    I am currently chasing an electrical demon around my 2004 Trailblazer. When we fist noticed the issue, the left front headlight was very dim, and then the engine would die when you turned the high beams on. Then about a week ago it just died and will not start at all. The first thing I noticed...
  2. [SOLVED] [not solved]05 tb won't start

    The 02-09 "How-To" and DIY Section
    I have an 05 tb lt 4.2 and when I try to start the truck nothing happens. When the key is on it says service brake system and the door bell is going off rapidly. And the dash lights are flashing. When you try to crank it, nothing! The battery isn't dead and I've been driving it just fine the...
  3. Trailblazer won't start or turn over. Struck by lightening

    General
    The other day my car was struck by lightening. Yes it is possible. So I walked outside to my car not turning over after three TVs were fried in the house. Everything lights up but when you turn key nothing happens. It does click from the fuse box but that's it. I have already tried changing the...

  5. 4.2 with no spark

    OEM Issues
    I've got a 2005 Envoy, 4.2, 4X4. On a couple of occasions it died on the highway. It didn't sputter, but just quit. I got it home and ran the codes and found none. I replaced the crankshaft position sensor and now it will not start at all. Plenty of crank, but no start. I checked to see if...
  6. 05 TB EXT will not start, again

    General
    This is the third time in 9 months that my truck will not crank. All lights come on. No codes. Battery if fine. Starter is fine. Security light does not stay on. But the truck will not crank at all. I took it in to Milton Chevrolet to get water pump replaced AND find out why it would not start...
  7. Starter won't start.

    General
    While driving my 2002 I6 Trailblazer, I parked it. Went inside for 30 minutes, came back out and the starter would not turn over when the key was turned to the start position. I thought it was a fuse/relay, and replaced the starter relay and checked the fuses I could find related to ignition and...
  8. [SOLVED] 2002 won't start hot, bad idle

    OEM Issues
    I have a 2002 trailblazer. In the morning, and after work, it starts no problem. After I've been driving around, I have to let it sit and cool down for at least an hour before it will start again. If not, it will try and turn over, and eventually (after 10 mins or so) it will start. This...
  9. Replaced water pump, now won't start

    OEM Issues
    Thanks to all the great help on this forum, I replaced my water pump with minimal problems yesterday. But, now my TB won't start. I managed to jump it off twice, but only if I pumped the gas pedal a little bit, I haven't been able to do that since though. The battery is only a year old, and I...
  10. Cranks but no start - injector circuit fault

    OEM Issues
    My aunt has an 03 TB that died while driving the other day. It will crank over but won't start, not even a catch. The towtruck driver told her that it was the fuel pump so she bought one and asked me to replace it. I can hear it priming when I key on, so I relieved all pressure from the schrader...
