I’ve been having a problem with my 02 trailblazer I turn my key to start it and it won’t start it works on the first turn but the second everything shuts off. On the first turn my rpm jump around from 2-3 and will not go down. The other day my vehicle stalled at a red lightning my abs brake light came on and wouldn’t move dose any one know what the problem could be

Do a PCM reset by disconnecting the battery for 30 minutes. While waiting clean your throttle body.
