Hi,

I have '72 240z with automatic engine. Recently, I have valve adjustment done and engine start up so smoother than ever.

Following modification is done to my car.

- Coil upgrade to MSD Blaster 2 (Register also replace that comes with MSD Blaster2)

- New Spark Plug (NGK BPR6ES-11)

- New Spark Plug wire (NGK Blue)

- New Cap

- '82 Maxima(280ZX) 60amp Alternator

Car runs good and stable. I have Three 240z distributors.

Original Distributor for automatic is dual point distributor. I works fine.

I got two single point distributors from 240z. I rebuild one of then the other is original condition.

When I swap Dual point distributor to single point distributor, I have no problem starting engine. Then I installed Pertonix Ignitor 1761 and connect Red line to Posititve "+" of MSD Blaster2, Black line to Negative "-" of MSD Blaster2.

Engine does not ignite.

I made sure installed rotor too.

My Pertonix ignitor seems new design and have enough wire length to connect to the coil. Also, it does not comes with plastic feeler gauge (0.003" thick). I don't know whether the distance from the air gap between module and magnetic sleeve is adjustable or not.

Try bypass ballast resistor does not work neither.

Follow the FAQ on the manual, connect red wire directly to battery to try to start, no luck.
