While waiting to have the 260Z tuned up to pass emissions, we decided to toy around with our non-running '73 240Z. Although we bought it non-running, we were able to drive it home from the PO's house after spending what seemed like hours coaxing it to start with carb cleaner shot into the carbs.

That was about a year ago, and the last time it ran. Now, it just cranks & tries to turn over. Yesterday, we pulled the carbs off of our (now once) running '71 240Z and put them on the '73, as the carbs that were on have seized nozzles. Still nothing. Today, we swapped over the coil & ballast resistor & bought a new condenser for the distributor. Earlier, the dizzy received new points & rotor. New plugs & wires rounded off the project and STILL no start.

I posted on this project in December, the compression numbers seem to indicate a new head gasket.

Our next step would be to swap out the distributor from the '71 as well, but I just thought I'd check here first and see if someone can maybe give hints on what else we should look for.

I was in the same boat you were recently , I just started with a test light and moved from the battery onwards or if you like from the dizzy back , I found alot of my issues were corroded and loose connections, good luck

This has been my lucky week for Zs... I found out what the problem was with the Z. The dist was bad; swapped one out from my donor Z and the car that's been sitting for over a year finally started! That leaves only one non-running project car (a Roadster) left to tackle.
