About 2 years ago I up graded to the new pointless distributor. put on the the approved high tensions leads. All was working fine tell today when it started to miss just a bit. It rapidly got worse and with in 30 seconds it was dead.
Was close to home so I pushed it home.
I started checking for loose wires to the distributor,and ground and to the coil All ok
then tested spark ant the plug and then at the coil
Nothing. It did seem like the distributor was sending a pulse to the coil.
Switched the coil out with one from a 944 Porsche.
It started and took it for a short drive with in 1 minute it quit and I had to coast it back home.
I think I smell a little electrical heat.
one more thing when the switched it turned on the ignition light comes on but goes out when the engine start and comes on for an instant when shut off
Any Ideas?
thanks

OK
went back and tested the out put of the distributor to the coil winding terminal.
I do get an interrupted 12 volts to the coil. So coil has to be bad.
It was a 3 ohm coil and with a poor test meter, it says no Ohms.
the coil from the 944 Porsche reads about 51 to 71 Ohm.
It is funny it would work a bit and then quit. I still get 51 to 71 Ohms
Will buy a new 3 ohm coil and let you all know what happens.
This stuff all too simple to cause this spooky type of problem

problem fixed
Turns out it was 2 or more items that failed.

the coil was one of them and the spark plugs were the others.
I did replace the rotor and the distributor cap.
the distributor was new 2 years ago and is the pertronic electronic system.
In all these years have never had something like this happen so fast.
Usually takes a week or 2
Unless it was rough handling of old spark plug leads during valve tune up on a v8.
Bearly would run after but it did run.
