Fuel pump Relay?
 

Hiya,

A few months back my Rover 75 2.5v6 auto Connie's engine would not turn-over, Chris kindly identified it was a imobilzer issues and quickly sorted and had her running again.

But now she wont start, even tough she now turns over. She slowly gets better and pretends she will start, but just doesnt quite get there. She had priviously started after the first turn.

I have been reading that it could be a Fuel pump Relay issue, but I'm not sure how to listen to the fuel pump, as been suggested elsewhere, as another possible issue.

Could some let me know the steps to follow to determine if it is the Fuel Pump Relay?

Thanks
JD

Open the fuel flap, remove the lid, turn ign on then put your ear to the filler neck, see if you can hear the pump humming..

When I turn on the ignition I can hear the pump priming. Only lasts for a couple of seconds.

Sounds too quick. Normally runs for up to about 30 seconds.--:shrug:

We are talking about Banana, who likes to be different.

The V8 also does this when you turn on the ignition, the pump primes for a few seconds.

Not on a petrol :)

There are several possibilities here Jay:

1. Fuel pump relay (unlikely). At "ignition on" it primes for only two seconds so you'll need an assistant to turn the key whilst you listen.
2. Fuel pump failure (also unlikely but it happens occasionally).
3. Crankshaft position sensor fault (if the pump doesn't run when cranking. It will still run at "ignition on").
4. Fuel filter canister separation (a favourite).
5. Camshaft position sensor fault (doubtful in view of your evidence).

Checking if and when the pump runs is a good place to begin.

That's Fuel Filter Syndrome for ya. Read through this earlier thread covering the same engine, the same symptoms, and the easy fix. https://www.the75andztclub.co.uk/for...d.php?t=316361

Thanks for the advice. I try these out when I get a moment.
