I just bought a 2005 Trailblazer Ext LTZ 4x4 last week, when i first tried it worked more than well and i decided to go ahead and buy it, when i finally pay for it i took it to home and after 30 minutes having lunch i came back to the Trailblazer and it didn't start.Answer: Seems like you use the truck let say for an hour and if you stop for 30 minutes then try to start it again it doesn't work, if you let the TB about 30 minutes more it starts again.
This is now with the correct dealer but they are working based on what the ECM reports but for me seems like it could be the starter motor or gasoline pump, they have change an interrupter on the starter and also a relay, they clean the acceleration system and we still have the problem. Now they are working on the fuse box to replace it and see if it works, I'm just tired about not having the right answer. Can you help??
Answer: When the truck does not start, does it crank and not start, or is the problem that it will not even crank over ?
