Earlier today my 280Z started right up and idled just fine as it has done for the past 9 years. It was idling for about 5-10 minutes then it just dies. No stutter, no chugging, no nothing, just dies as if the spark randomly shut off. So I test my spark plugs, no spark. Inspect the distributor cap, looks good. Check the coil, no voltage signal from the coil to the cap. And that's my issue me thinks.
So I pull the coil to test it. Primary circuit has 0.8 ohms resistance and the secondary has 22k ohms resistance. The values are a little out of range from what the book i have tells me, but they should still be close enough to send some sort of signal. I have 12vat the positive terminal of the coil and 12v at the negative terminal.
I have no friggin clue why it died and suddenly lost all spark. I did not jiggle any wires before it died, nor did I unplug anything, it just keeled over.
I can not find a Transistor Ignition Unit inside my engine bay, it was not in the location the manual said it would be. (Next to the battery) I am trying to sell my car soon as a driveable project car because I don't have the time or money to throw at restoring it and this random death of spark really dampens my day. So any help would be appreciated.
