O.k.,unfortunately after looking through my info on this here I dont see anything myself that would show what will cause this here but someone else here may have this info.

I will open your question up for others here to see if someone else can assist further on this as there may be others here that may have more info on what to check or do with this issue.I hope you can get this resolved with ease.No need to reply to my last post here unless it is a last resort as it will keep your question locked to me and others will not be able to view it.If you feel you want to continue to work with me on this feel free to reply at any time but keep in mind in some cases it can be difficult to fully diagnose or help repair this without seeing your vehicle.

Thanks Pete

Hello and welcome to JustAnswer!

It sounds as if you have a powertrain control module related issue. If it doesn't start along with relays and other items clicking that would usually be caused by the PCM not being fully awake.

Have you checked for PCM communication using a scan tool at the time the problem is happening?

Customer: replied 13 days ago.
No I did not ! Will try that
