Thanks for reading this. My 240 Wagon has started a bit strangely since I bought it a year or so ago. Symptom was advanced spark on cranking - seemed as if as piston was reaching top on compression stroke it fired too soon, and stopped the starter, sometimes momentarily, sometimes it would go over. Eventually it would start. I tried retarding the distributor, and this worked a bit better for a little while. In all cases, once it started, the EI control took over and there were no timing symptoms during normal running.
But a few days ago, it stopped starting. I pulled a plug, put it on the head, and spun engine with ignition on. No spark at all. Checked the code reader behind the LS inner fender, got only three blips indicating no problems. (Guess they didn't have a code for "no spark.")
Both coil primary terminals show voltage with test lamp. When disconnected and intermittent battery voltage is supplied, I get a spark from the coil HT line (to distributor.)
It's times like this I seriously consider such gimmicks as substituting the distributor for an earlier points model and just reverting to coil ignition. I'm certainly tempted here....
Any suggestions on where to go from here much appreciated..
