03 trailbazer ext shuts off while driving and cant figure out why

Asked by Nov 18, 2017 at 06:19 PM about the 2003 Chevrolet TrailBlazer EXT

Question type: Maintenance & Repair

03 trailbazer ext cuts off on my husband on
the eway, no warning at all. We put in a new
starter and battery, it tries to start but
doesnt lights comes on as well.There is a
switch under and blue light on the
dashboard and the truck has onstar so our
guess is that something with the alarm
system causing it not to start. Any
suggestions on how to maybe bypass the
alarm or anything?

Probably the crank shaft sensor ... it's a 2 wire device that has a plug at the ignition module ... it's cheap and easy to fix
