MX-5 NC with RX-8 231 Engine

Trailing plug was had a lot closer gap than the first one I pulled out. Might explain things.
Still need to trace wiring but daughter is doing my head in at the moment.

I can't get my head around this...
Even though the resistor is deleted, its still dropping 1v. How ever if I remove the loop completely it goes back up to 12v.
The below pics are with resistor loop removed

And these are with the loop installed and pump running

Ignore that. Got it running on the low circuit and measured the voltage and it was the same.

I traced all wires on fuse board ecu and they were fine.
Need to do pump tomorrow.

Also I haven't driven it since changing the plugs which may of sorted things

When I drive out earlier there was a miss fire at 4.5k nearly every time. Then if I held it at 6k on light throttle it was misfiring like a machine gun.
Going to take it for another spin and see if plugs have made a difference and go from there

I think the fuel pump is shot. Never heard of quantum before

Can I ask if you have code read the car and if so what codes did you get ?

OK,
Here's one that wont show up as a code.

Check the wiring colours on the fuel injectors to see if the plugs are on the right way around as this will give the symptom you describe.

Ive got a couple of piccys on my westy thread, making identifying the injectors and loom so much easier....bewarned they are a sod to get off...10 exhales try again....

Where are you mate? If you came to mine we can go right through it ? Ill find the piccys i done. Makes it so much easier to identify them and where they go...i went to that rx8 mx5 conversion and they were on wrong....
