Ive noticed a problem with my 4x4 saff,
When I switch on the ignition the fuel pump primes and runs on for 8 to 10 secs.
Even with pressure gauge fitted and holding pressure it still seems to prime for a longer time than usual every time over and over.

The car starts and runs fine although I do have a problem at high revs with leaning out and thought this problem could be related.

I was wondering what in the ecu controls the fuel pump relay?
Is it the chip?

Any help would be much appreciated.
