My 2003 Trailblazer will not crank up all the time. It will not even turnover sometimes other times it will turn over and stop. This has happened on numerous occassions for the past 8 months. I beleive GM is waiting for the warrenty to expire. They have replaced my ignition system and fuel system. It still has problems with intermittent cranking. It has happened at the dealership and that is why my ignition system was replaced. GM does not want to do anything. I have been stranded numerous times due to this problem. They got my money and that is all they care about. Please anyone I need help. Where else do I turn.

I have had several repairs done to my new vehicle. I have had the 2003 Trailblazer for 7 months and it has been in the shop 7 times-2 times for the coolant system-1 time for my master cylinder-3 times for my circuit boards-now for my steering and my starter( I believe my truck is in the shop as I am typing this letter) I have been trying to work with the dealership and GM but no one is trying to replace my truck with something that is not in the shop every month. Thanks.
