Paul, with my mk2 gti relay in, the car starts yet no noise, how strange??
A decent fuel pump and clean fuel doesn't make any noise.

Humm.., I not so sure
Well, I have worked on plenty of Mercs with K-Jet and the fuel pump is almost silent.

Point taken, but in my case the GSF pump relay can clearly be heard priming twice with the car door open, yet the VW mk2 relay is silent, strangelyy the VW mk2 relay starts up just the same. As with your thinking it's very strange indeed and can't really be understood.

If its the same fuel pump and the same car, but a different relay, your right, its confusing. The only possible suggestion is maybe, that a sliver of rust/dirt entered the pump one day, and the next day it didn't…..
The noise can only be 2 things: cavitation within the pump, or mechanical noise eg from the bearings. The mechanicals would wear over time, not magically fix themselves….right?

Settling In
Car starts but cuts out more or less after a few seconds.
On turning the ignition key the pump does appear to be very noisy tho. Do you think this is due to it being past it ?
