Car Randomly Died, Won't Restart (R32 Gtr)

[CabbageMS]

Hey all. Question time! A few weeks ago I was merrily driving along when all of a sudden, mid corner and off boost, the engine cut out. Attempted to restart the car, but it wouldn't have it, even jumping it off another car.

The situation:

• The engine turns over on the starter motor and nothing is obviously mechanically knackered.
• Connections on the CAS and the ignition amp have been checked.
• A new coilpack loom has been put in.
• A different ignition amp has been tried.
• I've determined there is a spark although it looks kind of yellowy-orange rather than the usual crisp blue colour.
• Fuel pump is making priming noise when ignition is turned on and I've checked fuel pressure at the rail and it's in spec.
• Nissan Datascan shows an RPM reading when engine being turned over, and injectors can be heard clicking..
• There is definitely fuel in the tank, over half a tank full.
• After a certain amount of time attempting to start the car, you can smell fuel emanating from the exhaust.
• The car sort of sounds like it will fire the first time it's turned over (sort of like there's partial/weak combustion), but then nothing.
• It sounds like the car has compression (engine is turning over at normal speed) although I haven't checked it on every cylinder yet.

On Nissan Datascan the water temp sensor displayed zero degrees, so I replaced that and it now reads 8 degrees, which sounds more realistic.

Does anything immediately come to mind to people?

Sounds like spark plugs are wet, have you tried another new set in there? Wants to fire then does not, most likely the plugs are soaked by that time.

Otherwise that yellow spark is not going to cut it, you need a blue spark.

Start with the plugs first, if it fails start chasing the weak spark.

Well I left the plugs out for an hour and cleaned them up a bit, also turned the motor over with no plugs in to blow out any residual fuel. Didn't make any difference though.

Also would be a bit weird if all 6 plugs suddenly degraded to the point of it cutting out while running though?

I guess it's feasible that the second ignition amp I tried (which was second hand) was duff to, is there an easy way to test them?
