fuel pump relay

[chatteris]

please could someone tell me the correct part number for a fuel pump relay for a w202 c240 1998 car would not start after being left for an hour, tried again later and realised could not here pump running when I turned ignition on so tapped on top of fuse box and tried again and it started so think relay might be a bit iffy.

In the fuse box in the boot, next to the Black fuel pump relay, there is a fuel pump fuse, number 1, White, which is 25amp check it to see if its ok.

car is fine today, it was the fuse box in engine compartment I tapped to get it going so if fuel pump relay is in the boot what would it be in the fuse box ,is there another fuse for the fuel pump?

Water ingress in fuse box, i should think that the ecu was not getting a signal, that's why the fuel pump would not work, check all the wiring in, and under the fuse box, and use wd40, or similar
