Hi Vortexers. I have a switch on the fuel rail, near cylinder no1, that has 1 blade connection for a wire. I can't find a wire that would hook to it.
Anybody know what this is? My car is a US model, 5speed and A/C. TIA.

exactly like he says !
the starting of the fuel pump is to avoid Vapor Lock

Does a good job cooling down your car (keeping the radiator fan on) and running your battery dead

Which is probably why someone removed it.

It does not cost much to replace, but they new one will have a yellow top this time......works just fine. http://****************.com/smile/emthup.gif
