Did you solve the problem?

My 260's is showing similar problems.

Was country driving when it just died.

Has spark, flows fuel and I'm bugggered as to why it has just stopped!

Replaced filter, new dist cap & rotor, still no go.

MN:ermm:

Never did get it started. I was just trying to get it started so I could turn the car around in my garage in order for me to pull the motor anyway. I finaly gave up and pulled the motor from where it sits. Now have motor at Rebello Racing for total Hot Rod rebuild and I decided to go with Mallory Unilite electronic ignition distributor. Probably wont have it up an running 'till next year 'cause rest of car is heading for body and paint. Will keep you posted.

Good luck on yours.

Well if the 2nd part of my advice didn't work, just make certain and follow the first part of my advice on how to properly shoot your car.

Mark,If your trying to start the same car as the hole in the floor.It won't.You must have a tach. A bad or disconnected tach=no go. Have fun!! Daniel

Well I finally solved it.

It was so fustrating that I'm posting the solution that in the unlikely event it may happen to any other poor unfortunate member.

It was all caused by the vacuum advance.

Just to clarify the situation as all zeds are different, my 260 came with a 280z/x hitachi distributer, so this may not apply to 240's or other 260's with similar symptoms.

The wire at the top of the capacitor had actually broken, even though the insulation was intact and a visible inspection showing all to be OK.

The cause of this was the vacuum advance, which, when advanced moved the capacitor against the distributor case. This over time caused stress fatigue and eventual breaking of the wire.

Very fustrating as a check for spark indicated all to be well [admitadly, the spark was weak] when cranking over but no spark when the engine starts.
