VS commodore problem starting

[tiersum]

Hey all i have a vs commodore and i have a problem with my car starting. The car has done about 210k the engine and gearbox have done 62k i have a aftermarket alarm and 3 point imobiliser installed. Original key is being used. car was serviced about 3 weeks ago. ignition cables are about 6 months old. New Deep cycle battery (4months)

the car has a problem starting when i turn the key after the immobiliser is disengaged nothing happens the dash is active lighing up but nothing happens engine wont kick over no starter or anything , i activate the alarm and disengage 1 or 2 times and it will start up fine im not really sure what it is. the dash is visually showing any faults , i guess the situation is somthing prevents the car from starting but when that fixes itself the car starts perfectly fine. Any got any ideas ? ? ? ? ? ? ? thanks in advance

Try a fault check first-
Checking error codes VR/VS (Revised)
But maybe it's the sensor on your key not touching your ignition it happens to mine every once in a while just push the key in a bit more when turning it over!!

the engine light isnt on so does that mean its error free ?

Not necessarily, best to check the codes to see if there are any.
