Hey Kolby!

Sounds like you've got an issue with your alarm module, causing the immobilizer to activate (also known as a "start inhibitor"). I'm not sure what type of alarm you've got, but this will probably help you find out if there is something wrong with it:

There is a panel with relays on it behind the dash. At the bottom of the steering column, by the drivers feet, there is a panel. Remove it to get access to the relay panel (just a couple of torx screws, no breakable clips as far as I can remember). Remove the "double size" relay (probably marked 210-211). Put a wire between the terminals 50E and 50F. This will hotwire the immobilizer and make sure that it always activates when turning the key.

Drive around with the wire in place instead of the relay for a while to see if this helps. If it does you'll know that the problem is related to the alarm system. Keep in mind that you will be without alarm and therefore probably also without remote central locking while doing this.
Make sure that the wire is connected firmly enough so it doesn't come loose. You can also put a fuse on it if it makes you sleep better at night ;)

Good luck!

hi can you turn engine over by hand [engine s not sezied ] and how did you test the battery and how did you test starter because if the engines not seized and you put a jump lead from your positive terminal off a good battery to a starters main terminal and it wont, turn over the starters faulty or there is no engine earth so connect the other jump lead from the negative battery teminal to the engine block and try again it will turn over if the starters good if the starter turns over with the jump leads check the small terminal on the starters wire is live when someone turns the ignition key if it is and the starter does not turn over then the soleniod on the starter is faulty if no live at small terminal then the ignition switch or starter relay are faulty best of luck yates2104546
