Hi ,Can anyone help.
V6 Petrol
Key opens doors ,key in ignition turns all electrics on .Red light next to automatic gear lever,when key is in turned engine will not turn over.
Have put seperate electric to starter motor,with key in on position, engine will turn over but will not start. thanks in anticipation Homer

 

Red light next to gear lever staying on is a immobiliser/security problem.
Have you a spare key you could try?

Car might not be recognising the chip in the key

 

Welcome to the forum Homer,

I see you skipped the New Member Area - Intro a MUST section and cut directly to the chase.

+1 to Tanis8472 suggestion that your immobiliser is still activated when the red light is on.
