740 with fuel problem i think

Where was the "big relay thingy" that you changed? Was it behind the fuses on the fuse and relay tray (behind the ashtray at bottom of console)? All the best, Peter

Hello Peter, sorry for the delay, yes thats the part, swapped it for one from a running car but still no luck! any ideas? ttfn

Is the fuel regulator ok? That is assuming that you have an injection engine. I had the same problem and had to get the whole unit replaced. I can scan and email the parts from the haynes manual for you if you like. email me directly at
