Engine Won't Start,

[gunjack]

Hi

I replaced the head on my nephews car after the head was destroyed by really bad detonation.Once the engine was back together it started and ran fine for a short period then it stopped and has refused to start again since.

I have cranked the engine over with the spark plugs out and the spark seems to be very weak, mostly a white to yellow colour, and somtimes its more of a mist looking then a actual spark.

I know to test the series 1 coils for a value between .6 and .9 ohms but what do you test the series 2 for, as they have the built in ignitor?

Does anyone know what values to test the ignition coils for on a series 2 RB25DET?

thanks for any help
