Asked by Jan 06, 2014 at 01:02 AM about the 1999 Pontiac Firebird Base

Question type: Maintenance & Repair

Have suspected body control module defective, it controls starting system. As well as my horn which does not work after alarm system stopped working. It will start up fine over and over, but just will not send signal to solenoid on starter. Can jumper solenoid/starter and car will start (with key on) but immediately dies. Ignition switch when turned on engages instrument cluster,etc... and battery meter on instrument cluster shows load /needle movement. So I don't think its ignitions switch.

....when it intermittently does not start - no clicking from solenoid/starter and no 12volt signal to solenoid. but intermittently it will get 12v and start just fine.

You're going to have to trace the harness, I'm afraid. There are two connectors between the ignition harness and the BCM, one or both of them might be loose. I've seen similar issues after someone has installed an aftermarket stereo or capacitor. The harness runs right in that area. These cars are notorious for poorly manufactured BCM's. You can get one for about $150. It's located under the dash behind the glove box compartment, not that hard to get to. Good luck!

Thx! you called it! one of the connectors that plugs into bottom of BCM was loose. Removing the bottom panel under glove box allowed easy access and view. I believe hitting a pothole was the cause of connector loose. I believe my BCM is defective for horn, but not for starting system.
