Where the hell is my fuel pump relay?

Post by Soperman »

My '85 M635CSi won't start and it looks like I have no-fuel issue. One of the obvious things to check is the fuel pump relay, but I can't locate it.
According the electrical troubleshooting manual, it should be positioned on the outside the main fuse/relay box under the bonnet - but it most certainly is not there.
Does any one have a good idea where I might find it?

That's why I love this site. Many thanks indeed Wattsmonkey!! Problem solved and she's running like a dream once more.

I'm gonna label and log every relay whilst I have some time, so the next time I have a problem I can get straight on it and not waste time. So I took a snap of the relays above the glovebox (RHD). Dose anyone know what all these are for?

Try pulling one at a time and see what doesn't work?

PS Do you still want my coarse spline Mtech1?
They are ALWAYS rustier than you thought!!!!!!

The tall, black relay is the timer delay for the interior lights.

Can't remember what the others are for!
