Petrol flap not locking

[gadgesxi]

My petrol flap never locks so is freely open for someone to suck a load of petrol out of!

Last time i had the boot in bits a noticed what looked like a solenoid that pushed a pin across to lock the flap.

Is it repairable?

Remove the solenoid & check its operation, but 1st I would stick a meter on the wires to it, check that its getting a pulse to lock/unlock, it works on a reverse polarity system IIRC, so one wire is live for say lock other is ground then reverses the wires to unlock, if you dont get any readings of the wires then its a wiring/fuse issue, not the solenoid.
