My Vantage wouldn't start after....
 

Today I had new front tires put on my 2007 Vantage. After driving about 15 miles, the tire warning light came on. I stopped, checked the pressure and found that the shop had put 45 lbs. of air pressure. I reduced the pressure back to 35, but after driving back to the shop the tire warning light was still on. It was suggested that I reset the TP module. I mistook the silver pin in the rear on the light module to be the reset button. So, when I stuck the ball point pen in and clicked it and then tried to start the car the starter turned but no ignition and the lights on the TP module no longer come on. What did I do???? Anybody have an answer??? I did all the locking/unlocking protocol to no avail. Even disconnected the battery and reconnected it. The car won't start, and is getting no spark to the coil. HELP!!

You need to check fuses, I'd start with F54 in the CEM 10amp fuse.

Thanks for the response J Double U, but I checked every fuse in the car and all were good.

The 'silver pin in the rear' you describe is not by any chance battery disconnect switch?? If that is the case it's a matter of pressing the 'reconnect switch' inside the cabin (on top of your battery) I assume [the DB9's reconnect switch is positioned there, not sure about the Vantage's]

He says the starter turned, so it's not a battery connection issue.

Can you send a pic of this silver pin?

Good point; I clearly missed that.
