My sons car lost power whilst driving it and after pulling over he couldnt start it (tries to crank but wont start). Still wont start after sitting overnight.
RACV came and advised that there was no power at the ODB port to diagnose further so left it at that and said an electrical fault. All other electrics seem fine (other than a blown tail light globe which we knew about).
I'll get a replacement fuse for the ODB a little later today but wondering if there is a relationship between ODB and failure to start?

Any other simple troubleshooting I can try before having to get it towed to Ford for them to look at?
