So I drive to the store (15min trip) and come out 10mins later and now it cranks but will not start. This has happened before but very intermittently (maybe one time per 2month), and always started after re-trying 1-2 times or waiting a minute. I walked home and plan to get a tow to my house tomorrow. Before I pay for a tow, what are some easy/obvious things I should check, requiring minimal tools? (I'll have to lug the tools with me to where I left the car).

Searching the forum, a possible suspect seems to be overvolt relay. Anything else I should check?

Thanks for any help!
