Thanks - I'll didn't check the images when posting!

No, with the normal circuit in tact I was consistently seeing 3v at each point - pump plug, inertia switch etc. However, last night I was seeing 12v at the fuse block and inertia switch which the day before had only shown 3v. With a new jumped supply to each point the pump runs. I'd have thought that somewhere along the cable I'd see the direct 12v drop and not work if there was a fault but I'm not sure anymore!

Yes that's right. 1. Correct, it either fails to prime or stops when running 2. Yes, 12v applied and it runs 3. No, nothing obvious I've checked at each point there's a plug or connector all the way back to the MFRU, including inertia switch and fuse block. With 12v applied at each point the pump runs, voltage generally has been 3v - so not right but then it randomly started working again. Then stopped! I've tried two different MFRU's, the relays work and one of them definitely had 12v at the terminal inside.

Interesting m, I wonder whether something like this would be useful in tracing my fuel pump electrics issue.....

I think I've checked them all but there's a chance I've missed something but don't know what, so far I've checked: MFRU / Inertia Switch / Fuse Box / Black Plug / Grey plug / Pump plug

EEK - MFRU is fine, had the cover off and can see the relay working and can measure the right voltage at the correct output pin.

Checked it all over Toby and all seems fine, no visible issues, wires don't seem damaged etc. Have moved it again tonight and checked again but it's still not working and I get 12v on the right sight of the fuse at key on and if I put 12v on the other side the pump runs so that implies that section is working fine - I think!

The pump runs consistently every time I can supply 12v to it and when it was running yesterday morning it was ok which makes me suspect electrics somewhere rather than the pump itself. its just what I can't figure out!

Thanks to my brother in-law being down I've finally managed to look at my fuel pump problem. Starting at the econoseal plug which the black plug on the side of the tank joins we tested the voltage which was measuring 3v. We also tested the pump operation by supplying it 12v and it worked. So, following it up the chain we tested the same things at each point we could and pretty much got the same reading and success of the pump working with a supply to it. We then started seeing 12v at the MFRU, (only thing we did before that was move the fuse box and plug everything back in again) and the fuel pump started priming again. Put the battery on charge overnight, next morning - nothing, pump not priming. Then it started working again of its own accord. Tried again today, it worked, fired up and ran for 3 minutes before cutting out and now I'm back to where I was. Anyone got an idea what is going on here because I'm now even more confused and out of ideas!

Thanks for the additional pointers. I may and try getting the MFRU apart again - I couldn’t figure out how it separated earlier! Will the pump always prime - regardless of fuel level? Just wondering if the gauge wasn’t reading correctly and it was empty would it still make the priming noise? The gauge was reading 1/4 and I’m sure it does have fuel in it but you never know!

Ah! Thanks. I thought being able to get to it fairly simply once I’d got the boot floor up was too good to be true. Looks like I’ll have to disconnect the fuel filler to get the floor out fully to get to it.

I’m not convinced the fuses have blown - it’s certainly no different with a new set of fuses and they don’t look blown on closer inspection I have managed to get the boot floor up and tested the supply to the pump (I’m guessing the pump is on the top of the tank) and it has just over 4v getting to it. I know there was a previous thread about a similar 4v reading but it has no conclusion so I don’t know what the fix is and can’t get into the connectors fo test where the voltage drop might be! I did try a direct connection to the pump with a fly lead but it still didn’t make any noise. I’ve checked earths, cleaned up connections etc and it’s non different. What else can I test? @Toby S - the relay I referred to was put in for the K click you can get with the starter, it’s a mod to the MFRU.

I’ll check connections tomorrow, was fine the day before! fuel pump fuse is 15A

Just went to use the car again, it fired up and cut out a few times and then the fuse blew again (assume that’s what the pop was followed by the fuel pump not starting again). Any ideas what may be causing this and what I can check out tomorrow?

Sorted - the relay bypass fuse had blown.

I went to start the car(2001 K series) this morning and don’t get the usual fuel pump whirring when you turn the ignition on and the car won’t fire up. I’ve checked the fuse, inertia switch, and the Immobiliser isn’t on. What can I check next? Typical, was fine yesterday! Cheers, Karl

I have 2 x tickets for England v Pakistan ODI at the Oval on 8th May in the Peter May I can’t go due to work now so if anyone’s interested I’m selling them at face value - £45 each plus whatever insured postage is, or you can collect from Beckenham / Victoria.

Ta. Just checked the connections on the back of the starter and it's fired up first turn.

Yes, the light goes out.

I went to start my car over the weekend and it wouldn't start, the battery has been on charge and whilst it seems fully charged it shows nothing when cranking so I ordered a new one. I've just fitted that (checked it was charged before swapping it over) and it still won't start. It turned over twice but wouldn't fire up then it just labours to turn anything over and just does nothing. Bloody annoying as I'm meant to be heading off to meet the family on half term holiday tomorrow! What can I check / do figure out why it won't start? Cheers, Karl.

Does anyone have a safety devices roll cage (think that was an early roadsport cage) fitted that they could send me a picture of how it’s mounted to the side of the car? I need to replace the bolt on the drivers side which goes through the side impact bar but can’t find the right one - it looks like a coach bolt, every other fixing available is a hex bolt. Karl

I finally go round to getting a new nosecone after my altercation with an X5 some years ago. After much fettling it’s now on but the grill that goes in the front seems way too big for the hole. Did the design of these change at any point (my car is 2001) or am I just not being brave enough in bending the fibreglass to get it in there?! Karl

That was me on my way down to East Wittering. I saw you flashing but can never move fast enough to flash back
