My car cas developed a strange fault. Normally when you turn the ignition on, you hear the 'whirr' noise of the fuel pump priming. Lately, this sometimes doesn't happen, and if I try to start it it doesn't fire. If I turn the ignition off and on a few times, it will eventually kick in, then the car will run fine until the next time i turn thr ignition off.

I haven't really looked at it yet, but can anyone suggest anything to check? So far, I've come up withthese as possible areas to look at:

1. The fuel pump.
But it seems to work fine one its primed, so that suggests it's ok.

2. The ignition switch.
Dodgy contacts maybe?

3. The fuel pump relay.
But once it has switched on, it does seem to stay on.

4. The ECU.
I really hope not. Has anyone heard of this problem before?

Any suggestions welcomed, thanks.

My money would be on the fuel pump relay, had the same symptoms on my G40!

I took the relay apart and found the contacts were burnt and pitted, a new one was only five or six quid.

Ok, i'll check that out first then. It's reassuring to hear that someone else has had the same problem and fixed it easily enough.

Thanks!
