Thread: Vehicle Not Responding.

I just got done rebuilding the entire top end tonight. It started up just fine, but, as I expected, the check engine light was on. So, I went to connect my scan tool to pull the codes and it would not connect. I've never had this happen before, and yes, the ignition was on. What would cause that? Thanks!

Check you cig lighter fuse, if that is blown, no OBD 2.

On 04+ you would check the onstar fuse and tell Drunkie to put it back in.

The cigarette lighter works and I've checked most of the fuses. So far, I haven't found anything.

Bill, funny you mentioned the On Star fuse. I was thinking about removing it. lol!

After more time with the car, I noticed the following: ABS, SES lights are on, TCS defaults to off and won't turn on, the DIC flashes zeros on all settings, and there is no boost display. Did something get shorted out? Did I miss something? Otherwise the engine runs pretty nice considering it now needs tuning.

Did you swap pcms?

No. The A/C won't turn on either. It did sit for eight months without power--if that makes any difference.

Hmmm shouldn't have anything to do with any of it.

Have you tried the ole ....kick to the tire? You know..tough lovin?

ROFL! I'm going to try disconnecting/reconnect the battery routine.

No good. Maybe an issue with the BCM?

I cleaned that one and a few others.

Fixed! I forgot when I was making my fenderwell block off plate, I disconnected the round harness that the upper brace holds in place so I'd more room to work with. It's dnyo time!! Whew! Thanks for your help guys!
