Hi guys my first post so thnks for letting me join. I have 2.1 td 406 that occasionally refuses to start in spite of recently being fully serviced and having the glow plugs replaced. I have been told it may have something to do with the fuel pump any ideas ?

Thanks in advance

Liam

Welcome to the nut house

When it fails to start, do you notice any difference in the noises it makes when you switch the ignition on prior to engaging the starter? Personally I haven't worked out what's what in the little symphony my 406 gives me before I start it (can you tell I'm in a good mood with mine today?), but apparently one of the whirrings is the fuel pump doing stuff which means a change in the sound (perhaps a particular whirring is missing?) could well indicate a problem with it.

Also, it's not your immobiliser kicking in is it?

I can't really hear the pump whiring either way if i'm honest. I do know what you mean it was quite loud on my previous SRI Turbo 406. The key not disabling the immobilser is posible i suppose but i'm sure i read somehing somewhere about fuel pump related probs with the 2.1 TD lump.
