Lately my 94 740IL has been having problems starting. It didn't start for
2-3 days over last weekend, started and ran fine Monday but hasn't started
since. All the electrical systems in the car are fine, the battery is fine,
no other issues going on. Funny thing is, when I drive to work and it won't
start at the end of the day, if I wait 20-30 minutes it starts right up,
which leads one of my co-workers to think it could be vapor lock. I've only
had this problem when the weather is 75+. Any ideas?
