Hi all. Got a issue with my classic 99. When I turn the ignition on the pump will prime like they do but then it will carry on priming then the radiator fans will kick it. It starts fine. What could the problem be? The relay maybe ? Cheers Karl.

Has it always done this?
Check to see if the green and black diagnostic plugs are plugged in,if they are then unplug them.

Not always fella. It got stolen so I put new ignition etc on it. Starts fine just when u turn it to 1st click.
What wires u mean mate the ones in the coin tray. ?

You only have them plugged in for diagnostic/test and ECU reset

As above they are plugged in to run test, they turn the fans on and run fuel pump constantly plus boost control circuit if they are plugged together then unplug them.

That's why the boost control unit clicks then when I think of it. Cheers fella you have been a great help.

Sounds to me like you may have an air leak or pressurisation issue somewhere in the tank or fuel system. The pump will prime to pressurize the tank. If there is an air leak this will take longer or not be able to pressurize at all. Does it drive ok?

Have a look at the fuel pump relay then. It may well be stuck on.
