help, car won't start

I've had the same problem on my 68 RR converted to electronic, may start 10 times in a row then it will not start just crank, sometimes i have to crank it 10 times before it gets spark. I'm leaning to the dist pickup reluctor or ECU.

It wouldn't hurt to check the distributor reluctor gap as stated above. I've had that problem myself. Double check me, but I think it should be .007".
