560sl fuel question
 

86 560sl

If the fuel pumps don't hum when you turn the key to start that means a bad fuel relay right? (sometimes they do hum so I know the connections are right)

thanks.

I haven't driven the SL in a while, but if I remember correctly they should hum initially as 126's do..in which case your relay is in fact bad.. Is the car not starting?

Intermittent no-start
 

If I crank it in the garage and pay attention I can hear the pumps hum as an indicator that it will start. If I turn the key to just before crank and don't hear the hum, it isn't going to start. Hum=start.

I went through the glovebox and jiggled what I think is the relay and it started first time this morining -I don't suppose I could be lucky enough that it was just loose but I'm hoping.

What's the going rate for a replacement relay? In Alpharetta by the way.
