C5 1800 petrol?

[wheeler]

Yes, from your VIN.

Yes, from your VIN.

Yes, you are quite correct, the part is available.

Told by the dealer a few days ago NLA, now told next day delivery from PSA!

Ordered, can't be bothered pulling the existing apart!

Thanks for all your help so far.

Sounds like you have the same problem I had many years ago on our 2001 Xsara Estate. I never did find out what exactly the problem was and bypassed the fusebox to feed the pump directly with a new fused supply.

The bypass was still working fine when we got rid of the Xsara in 2017.

I suspect this is just a failed internal relay. Your Xsara was the older setup with an external Double relay. I can almost guarantee your Xsara was a high resistance in the supply to to the double relay. Normally caused by a bad connection at one of the big round connectors behind the ECU, i have had to do this repair more times than I could count. I normally run a new supply to the relay. The telltale sign if this is the problem is you measure the voltage at the fuel pump & there is round about 12v but if you check it with a bulb there is not enough current to light the bulb.
P.S. You should never bypass a fuel pump relay (with the exception of testing) as it could be potentially dangerous in the event of an accident or severed fuel line.

Eventually fitted the new part yesterday.

Instant start and back on the road.

Thanks for all your help wheeler; most appreciated.
