My 2002 Trailblazer is in the shop for the third time because it will not start. I jump in, turn the key, all instrument lights go on, headlights on, yet you hear nothing. Tow driver puts a jump on it but nothing. Took it to dealer twice and they say they can not find anything wrong. Any ideas ??

There are 2 GM technical bulletins concerning intermittant no start conditions on your vehicle...have the dealer reference #02-08-64-017 and #02-06-03-001

The most difficult and frustrating part about intermittant problems are they are hard to duplicate..if you can't duplicate the complaint, you can't fix the problem

Tennis - you are not alone!!!

I bought an '03 Trailblazer in October. November, after driving more than 2 hours, it would not restart for 45 minutes. On other occassions, this has happened. It's been in the shop 6 times, but malfunctioned total of 10.

Now....I took a 400 mile trip and at my destination in Tunica, MS, I vallet parked the truck. After 4 hours, I went to retrieve it and they asked me if I had a Kill Switch. Uh oh. After trying my magic of disconnecting the battery, as usual, the truck still did not start. I waited 5 hours and tried again. No luck.

This was 3 days ago. On-Star and the dealer have done MULTIPLE diagnostics. On one SINGLE occasion, On-Star said that the Powertrain Control Module was malfunctioning. My truck is still in Tunica, MS and I am home, 400 miles away. Nobody knows what to do. I feel your pain, brother. I am paying $580 per month on my Trailblazer and they got me in a Cavalier with 40k plus miles on it.

I had the same problem and they replaced the ignition switch.

I'm having the same problem, jump in to go and nothing... The latest is that I tilted my steering wheel up and it killed the engine.

When I bought my '03 LT, I was having a key made for my wife at the dealer and the lady behind the counter said you better take those other keys off (I had 3-4 other keys) or your key switch will fail. (I had 3 yrs of warranty, so I disregarded her...) I have also seen it mentioned on the board a few times, that having to many keys will cause it to fail.

Now, with ~1000 miles left on my warranty and my truck in the shop for the second time because of this, can the "to many keys" theory be true? I would hope Chevy could design a key switch that could handle a few keys hanging from it!!!

The extra keys theory, I believe is based on the weight rotating the switch back slightly to off, but wouldn't hold up for the no start condition, which could just be a bad ign switch.
