Hi all, have been reading these forums for a long time but first time poster. Happy to be here I bought a 71 240z that was sitting for 4 years. Engine is complete, and cranks well but does not start. I already suspect a carb rebuild... But I thought I'd start with spark. When I first got the car in my garage I noticed no spark at all from the coil to the valve cover, cranking or not. Saw that the guy i bought it from wired the Pertronix Ignitor negative wire to the positive post on the coil, and the positive wire from the Ignitor to the ballast resistor. Since its a 3ohm coil, I wired the Ignitor properly to the coil. Now the coil wire does not spark to the valve cover while cranking, but as soon as I let off the key it sparks strong 1-3 times. I have replaced the ignition switch, rotor, coil, and dizzy cap with no avail. Jumped the battery to the Ignitor and still, same condition. Next steps are new Ignitor, and new starter. Any suggestions will be greatly appreciated, thanks for having me on the forum.

This morning i decided to swap the ignitor installed on my 240z and after opening the distributor cap i notice something is missing, i guess it could be the ground wire,so i fabricated one with 2 terminals and installed a new pertronix ignitor model 1761 together with a 40511 new 3.0 ohms ignition coil. The car cranked up fine, but whenever you step on the gas the tachometer does not read correctly. Once it reaches to 5,000 RPM it jumps to 7000 goes back to zero, etc. If you have the car parked and step on the pedal it raises to 5,000 goes back to zero. Bottom line it is not Reading as it used to read with the former ignitor. What could be wrong here? Could i have missed something? I have attached pictures of the original 1761 ignitor and the one i just installed which is giving me problems. Your advice is highly appreciated.

I've seen some walk throughs(mustangs..) that show that this has a plastic gauge to set the gap, but mine didn't come with that. has anyone installed one of these systems>? (this is actually on my '72 skyline, not a Z, but i bought a Z ignitor.. they don't make one for the skyline) My L20 engine is pretty much the same as the Z, just smaller.
