Presumably if it was the position sensor i'd still get an ignition light and the fuel pump would prime but theres nothing happening until the key is turned and the starter tries. So no ignition light and no fuel pump. This leads me to suspect a failed barrel in some way.

Yes, that's the logic that led me to suggest the switch.

But if anyone has another suggestion about why the starter still runs...

When I saw your 7 a few weeks ago (tyre delivery!), I think you said that the 2.3D was a transplant into your older chassis?

What chassis loom, fuses and relays do you have now?  Were they modified in some way, or are they now standard Duratec?

And a couple of thoughts:

When you turn the IGN switch to position #2 (to energize switched circuitry but without spinning the starter), do other switched components such as indicators and brake lights work ok?

Are your relays pushed firmly into their sockets?

Re #13:

That's what got me thinking about relays, Jonathan.  I imagine the starter relay is energized in IGN position #3.

I did think relay might be a possibility. Everything works (lights, indicators hazards etc) but no ignition light. Relays are pushed in but might have failed. Loom is as it was when it was K Series as are fuses and relays. Been like that since transplant in 2009 with no issues.

"The engine turns over fine but no ignition light and no whirring prime of fuel pump."

"Everything works (lights, indicators hazards etc) but no ignition light."

Please can you confirm that the indicators work with the ignition switch ON but not OFF. The main light switch and the fuel pump and the hazard lights aren't ignition-switched. The fuel pump and the indicators are ignition-switched.

Do you get a flicker on the ignition warning light as you first turn the key to the START position?

I think there may be a typo there, Jonathan. Wink

Re #15:

What year was the K, and was it EU2 or EU3?  (I'm trying to identify the matching wiring diagram -- as is JK, no doubt!)

Are you running other K components, such as fuel pump and alternator?

Thanks, John.

Should be:

"Everything works (lights, indicators hazards etc) but no ignition light."

Please can you confirm that the indicators work with the ignition switch ON but not OFF. The main light switch and the hazard lights aren't ignition-switched. The fuel pump and the indicators are ignition-switched.

OK So in an idle moment i swapped the 2 relays (They are the same part) moving the top one to the middle relay position. Ignition on and fuel pump priming but then after putting the bottom relay back in the car is dead again. Taking bottom relay out again made no difference it's still dead again so I am now assuming that there is a short circuit knackering the ignition relay.
