Im gonna suggest, that you have a problem with the gearbox neutral switch, this is the electric switch on the gearbox that tells the ECU that you are in Park or Neutral, and that it is OK to start engine because you are not in gear, it should be pretty easy to confirm by using a multimeter on the switch output when in neutral, as compared to when in park.

It will still have an inhibitor switch, they can be either on the T-bar, on the side of the box or inside the box. I'm not sure where they are on yours though...
They are normally able to be adjusted by simply loosening them and realigning them. If the switch is stuffed you can just bridge the two wires together to fix it on the cheap-just means it will start in gear, if you're silly enough to do so.

If it does have an ecu it'll be in the passenger side kick panel ......... I think

Does not matter, as mentioned above, no matter what engine or car, if its "auto", it will have a safety switch to prevent the starting motor activaiting with the transmisson in gear !

Only bypass the switch for testing, a permanent bypass will eventually end in tears, or death.




Reminds me of a mate who fitted a remote "auto start" car alarm to his car, this system allows you to start your car from inside the house with the alarm key remote, and is only allowed to be used on auto cars as they wont ever start in gear.

My mate wanted one but had a manual car, he never let anyone else drive his car and he always left it in neutral so no problem, until...... one night he was out ,and his brother had to move his car, he put the car back in the same spot, and you guessed it, left it in gear.

Well the next morning under remote start function, the car drove itself through the garage door and into another car, and he was lucky no people got injured, could have been a very different outcome.




So yeh, dont booby trap your own car for someone to get caught out in the future, at the very least you could use a momentary switch to bypass the function, at least that way you have to press switch and turn key at the same time, personally id go to a auto sparky or try a switch from the wreckers

If you've ever started an auto in gear you'll realise it's not that dramatic.

Neutral switch, and it cant break anything but can get worse and is embarrasing and annoying
