I have a CRX SIR vtec Turbo

B16A1 engine with an OBD1 conversion, i have had the car running since the conversion.

Changed the spark plugs the other day and tried to start it the day after. It would not start. I took a spark plug out and earthed it on the engine block to see if there was any spark. No Spark!!

I then tested the engine earth. thats fine!

Changed the ignitor in the distributor as i had a spare one from my OBD0 distributor. Still no spark.

I have listened to the main relay and that clicks on and off as its meant to.

Done a search for any suggestions and it came up with what i have done so far.

Any other ideas?
