Trailblazer won't start.
After changing the radio trailblazer wouldn't start. It started right before I
reinstalled the dash but after I put everything back together it wouldn't start. All
lights work radio but nothing when the key is turned.
check the battery voltage....should be 12.5 volts and the age should be newer then ten years old...the connections should be free of corrosion...disassemble and wirebrush them clean~ check the ground connection at the radio~ think about your troubles are related to the ground of the car....one insufficient voltage, chassis NOT grounded....good luck...you will find the trouble..it's ground related~
