The old circuit is still "made" so I have incorporated a flick switch in my new circuit which will only need to be active if and when the car conks out again - maybe in 6 months time if following previous scenario :) Thank you all for your help.

Ok - Car has been running fine for a few days then today it would not switch off - key out - it just kept running. I need to add that the original key is strapped to the ign lock immob ring - so NATS is effectively disabled. I can only assume that the broken wire (which caused the cutting out)...

10A seems a bit on the high side to me - but hey ho.

Thanks for clarifying AS. Just a bizarre coincidece then? What value fuse for injector wire please?

Hi Tsoob, Resistor packs - what resistor packs??? Where are they?? PS I hard wired the injectors not the ign!!

Thanks FHM Soldered wire from ign sw W/G to Inj W/G with fuse Success. Starts and runs nice. Then one of the coils packed up - quick trip to breakers and back in action. Just need to put it all back together now:( Thanks again

Good idea - I'll run a wire from W/G at ign to inj and see what happens. Thanks

https://www.micra.org.uk/attachments/k11-wiring-nats-jpg.17005/ On this dizzy diagram W/G goes to M29 - whats that? It also goes to ECU terms 4, 12 & 36 Where should I splice into it?

Thanks again FHM Yes it is still the G/W wire on this year (from ign to inj) & yes I get 12V ign ON at the sw. Pump seems to run OK when engine running. Oh for a wiring diagram :(

I put 12v into inj plug 1 and the engine starts – whoopee – albeit on 3 cyls. I just need an elegant way to feed the inj’s maybe wires to dash plus flick switch? Where to intercept the inj wires? Don't really want to fit a scotchlock above inj plug. I got the colour code of the inj 12v wire...

Thanks FHM Is there an easy way I can separately feed 12v to the injectors to test your prognosis? What could cause the pump not to activate/pressurise when ign sw ON but still ut work when cranking? The pump used to activate when ign sw ON.

Thanks FHM Thats 0.56V at injectors with IGN ON but not Cranking - I couldn't do both at the same time!!. You can't have 12v at injectors with ign ON (No cranking) otherwise the cylinders would get drowned ;) The 0.56V at least proves continuity in the wiring - doesn't it? If - as I believe -...

Ok so this is where I am ATM: I have not received the ECU Kit yet. I have a spark Fuel pump does NOT come on with ign to pressurise. Fuel pump does come on during cranking and for 1/2 second afterwards. I have 10.9v at fuel pump plug during cranking.. Fuel is returning to tank during cranking...

Just a thought - could that be the radio connections?

All injectors: click when 12V applied have no resistance (not shorted) have 0.56V at each injector plug with ign on. Looks like injectors & wires are OK.

Does anyone know if injectors are wired in series or parallel? My M8 came up with the idea that if its 'in series' then if one faults they all do.

Here ya go:

I reckon the ECU is stopping the injectors from firing - the problem is - what is telling the ECU to do this and why - or is it just a faulty ECU? I've ordered an ECU kit on the basis that there is no immob module on a 2001 car. Hopefully I can rule out a bunch of things when fitted - if its a...

Can't find injector fuse in Eng bay or cabin. All fuses I can find are good. Earlier I tried to lift injectors out to do a spray test - but they wont budge. Can I bypass fuel pres reg? How do I recognse it? When there is a spark, what else could cause the injectors to stop firing?

Ok - fuel is returning to the tank. No voltage accross injector plug connections. I agree - more chance of winning the lottery than 4 injectors packing up simultaniously ;) Engine statrts if I spray petrol on filter but stops after a couple seconds. Would fuel pressure regulator stop the fuel -...
