The first paragraph will be a little bit of back story.
I rebuilt my 260z mechanically this past 2-3 years, paycheck to paycheck, learning from my first project car. I have tried to do a sensible OEM+ type modifications. Last year I drove it 100 miles burned 2.5 qts of oil and decided to rebuild the engine. Fast forward i have redone the engine bay wiring harness while the engine was out. RELOCATED the ignition coil to the other side of the engine bay. i drove the car 50 miles after the rebuild then lifted it back on jack stands to do the suspension bushings and shocks. I also did a bit of wiring upgrades and buttoning up parts in various places.
I have a no spark issue. I with the help of others close by have determined my problem to be a distributor problem. I took apart the dang thing and it looks like maybe a wire disordered or maybe even 2 had and these are needle thin wires inside a 280zx non turbo distributor with a black box on the side taking over the roll a points system would do, ECM, electronic control module. i bought a junkyard one that looked nicer than the others but had a non OEM ecm. this part did not solve my problem and test faulty by my method of use a digital multimeter. the 123 Distributor is slightly more expensive and a replacement I could find in descent quality. it will be interesting to see what results I get from this distributor.
pic is the dizzy from the car originally, has reman marked on it, also its of 80s tech in a 74 car. the tiny wires I tried to solder them but just didn't work out for me.
