Car Alarms: car alarm system to deter gas thieves, car alarm system, locking gas cap

Question
I have a 2002 Chevy Silverado (Reg. Cab, 2WD, fleetside), and I have had my gas siphoned off at least 3 times recently.  This morning, they left me on empty!  I want something to deter these guys.  I had a locking gas cap, but it made my check engine light come on, so went back to the non-locking.  Thanks for your help.

Answer
The only thing I would do here is to
place a pin switch trigger on
the fuel door. If it it pulled
open, it would set off a car alarm system
you would install with a loud siren.

If interested in this sort of device,
contact me by phone so I can go over the variables
and costs.

You can get this done for under 150.
