I switched into Map 0 this morning and I am waiting to see if it happens again.

Have you ever come across this fault before? If yes why and what is the solution?

Warm Regards,
Hi George

I think I prematurely agreed that this problem was rectified. After changing the fuel loop to 45 I still got the starter issues after a while. I then ran the car on Map 0 for around 2 months and the problem disappeared completely. After changing it to map 1 on the weekend everything thing ran fine initially until the same issue started again. It seems to start fine in the morning however after a short drive and stop, on the restart, it had a hanging starter like there is no fuel. Once I turned off and tried again it started again. Please assist me, I hate not having my jb4 on.

Warm Regards,
