Hi all. I finally got around to fitting my new fuel pump and now the old girl is raring to go!
The only problem is when I start her up the EDU in the dash reads 'Err' for a few seconds and then goes back to showing me volts/mpg etc.
Any ideas of what this could mean?

Thanks, Billy.

It means one of the figures it wants/can show is faulty.

Depending on age the displayed things could be:-

Volts,
Av Mpg
Temp
Distance to empty
Instantanious mpg (for auto's)

Any more?

Do any of the options you used to have no no longer work?

Have you tried doing an 'R' reset, or failing that a battery -ve lead off reset?

Andrew.
