That sounds like something aftermarket impeding the srarter solenoid signal. Like an alarm, or a hidden security switch to start car, or a remote disable device, etc.

 

I have an alarm system fitted so I will it out. Thanks

 

Check it out I meant

 

Bingo, found it. It was the alarm system that was causing the issue. I fiddled with the alarm fuses and wiring and then had a cranking feed to the starter solenoid. I will spend more time now to identify exactly which wire was causing the problem.

Thank you Car Analogy for the heads up on the alarm and to everyone who has contributed to this thread. Cheers

 

Glad you found it!
