no i have to turn the key 2 clicks and it comes on then 1 more to fire itt up before it returns to pos 2, cheers for the advice about the switch will try it

thats the same as mine dude. its a switched live, the stereo comes on after the first click in the accessory position. i'd have thought thats how everyones works as pos 3 is only used to start the car.

i did think that but all the write up for the diagrams suggests otherwise have other people run it like mine?

it should technically come on on position 3 or when the oil pressure is high. see your other post.

The era was wired through thru an oil pressure switch, so that in the event of an accident and the engine stopping, the oil pressure drop would cause the switch to open and stop the pump. Only problem is how do you get fuel to your engine before it fires into life (maybe not enough oil pressure from cranking on starter & slow). So a link from the starter solenoid was run to the fuel pump. When ignition at 3 the current flowed to the pump from the solenoid untill oil pressure was sufficient to operate the oil switch.

What i would suggest is to use an inertia switch (as used on injection minis an loads of other cars). This should be wired in in series with your pump from pos 2 on your ignition switch. The switch MUST be solidly mounted to a bulkhead so it can feel knocks in a crash. The switch cuts your ful as soon as you hit anything. I think thiss is better way than original as you could have a crash that leaves your engine running / fuel pumping.

i run both era system with an inertial switch but bear in mind what other people have recommended that the inertia switch should be wired to your ignition to to avoild excessive lean out should you hit a pothole etc and your pump might cut out

no longer a series, but still 1.3 turbo.

what do you mean by lean out, i think i have the wiring sorted now much simpler than the era diagram. i will post a diagram once i do a few more checks and if anybody wants it! cheers for your help
