[COLOR=rgba(0, 0, 0, 0.701961)]Ok so here's the crack, I finally found a Micra that wasn't rotten so I put an sr20de in it from a 98 Primera GT. I'm running half Primera half Micra loom. Using the multi plugs from the Micra engine loom and Primera interior loom I made an adapter loom that just plugs in to combine the two. Almost everything works engine lights, gauges, immobiliser etc even the consult port is wired in. I have removed the immobiliser because I don't have the original radio. I done this by starting the car and then removing the nats control module, it worked on my old Micra of the same age.
Anyway the car starts without the immobilser but it cuts out the second you give it any revs. I'm pretty sure it's not an immobilser fault because I have fuel and spark.
When the engine cuts out the spark and injector pulse are still going until the engine physically stops rotating. After its cut out it takes loads of cranking before its splutters back into life again stinking of unburnt fuel. When checking the spark to me I looks really weak but my more experienced work colleague thinks it looks ok. I changed the plugs, rotor arm, dizzy cap and HT leads it will Rev a tiny bit higher now but still just dies. No voltage drops at injectors, coil etc I've checked all the earths and cleaned the ones on the inlet manifold checked fuel pressure is bang on(sr20 pump). I've checked the resistance of the coil autodata says between 0.5 and 1.0 ohms for the primary but I'm getting 2.2-2.7 ohms with a good multimeter?
Here is a video of the spark with the resistor bypassed.
I bridged the wires on the consult port to get the engine light to flash codes which it did
143, 145 and 21 I watched it like 20 times and I can't find out what 143 and 145 is? I Assume they are something to do with nats and 21 (ignition signal malfunction) has come up because I bypassed the resistor?
Any help would be greatly appreciated as this and a radiator is the only thing stopping me from flying down the road! Cheers [/COLOR]

. After going over and metering out the wiring a million times and finding no faults I decided to plug nats back in to see what happens and it does the exact same thing injector pulse, fuel pump primes and I have spark etc.
