Well as Jai wrote on another post, we had a great time improving the lights on 'Tippex' - Jai's white Mk1 Uno Turbo.
However, I didn't get anywhere with the other problem: the fuel pump doesn't run when you turn the ignition on. It should give a short 'buzz' for a second or two.
The result is that the engine is slow to start - cranks over for several seconds.
I noticed the oil pressure warning light wasn't working. Thinking that may be an 'engine not running' input to the fuel pump relay, I fixed up the connection to the sender so that the light works. Didn't make any difference to the fuel pump.
I then explored the fusebox, checking all add-on fuses and identifying the add-on relays. One particularly interesting, large Lucas relay turned out to be for the (now-defunct) dim-dip system. That's not shown in the wiring diagrams (it's a UK-market variation).
The Haynes manual incorrectly identifies one of the add-on relays as being for the fuel pump. I'm sure this is wrong because I figured out that one add-on relay is the foglights and the other is the high-speed for the radiator fan. Other than the dim-dip and the two relays that are part of the fusebox (heated rear window and horn) there aren't any other relays there.
At about this time the electric windows stopped working - I fought for ages without success, cleaning and fixing connections.
Anyway - the windows started working, and we found that if we operated the windows (key-on, engine off), the fuel pump buzzes...
So - what is likely to be the problem, please?
Thanks,
