w124 e280 m104 hfm flooding?

[DanF]

Hi all and happy new year.

I foolishly moved my car on the drive a little a couple of days ago and now it won't start again. I think it is flooded.

It cranks and won't start. I can hear the fuel pump prime and smell petrol.

If I remove the fuel pump relay it will start then die when the fuel runs out.

When I replace the relay it cranks and won't start. This is repeatable.

I have tried flooring the throttle as per manual to clear out the engine and that does not work.

Can a bad fuel pump relay cause over fuelling or should I be looking at something else?

History is good on the car with new loom hg coils plugs and ecu etc and it has been reliable since ecu replaced 6 months ago.

Thanks in advance,

Dan

ok i fixed it, about the 10th time of removing fpr, starting it, replacing it then it not starting, it fired up, so fingers crossed it will be the end of it.

daren't start it again until I need to go somewhere...

new years resolution to make blink code reader, take care all.
