The relay gets involved, yes, but if it were the trouble, you wouldn't have any fuel pumps either.

Sounds like you've made some mods, installing something non-Bosch and something to watch the sensor output. I'd suggest you check over these new connections.

Engineering says: "Modifications are underway to correct certain minor difficulties"
Engineers meant: We threw the whole thing out and are starting from scratch.
