cooling fan

I had the hood up the other day and noticed a wire disconnected. So I plugged it back in and the cooling fan that blows onto the injectors turned on kept running even though the engine had not run at all to that day. Is there a relay or something I can fix to get this blower to run properly. I live in florida and read that this blower is important at keeping the injectors cool for reasons explained in other threads.

excuse my ignorance but what is vapor lock?

 

Vapor lock is the phenomenon of fuel evaporating in the line due to heat, and causing a pocket of gas within the fuel system that impedes pumping. Vapor lock used to be very common on cars with fuel pumps under the hood; ask your parents, or anyone that was driving in the 60's and 70's what Vapor lock is; they likely encountered it very often in the summer.
