so, here's a pic from the FSM

It's telling me to check resistance between points, C and E. C is the ignition coil and then E is some random point on the distributor cap. I don't understand where exactly they want me to put the lead for E b/c it's just plastic. lol. Maybe I'm missing soomething?

alright if you look at the picture youll see that they tell you to disconect the connector and test the two pins in side of it(on the distributor). thats it check accroding to the picture and youre set. whats wrong, car doesnt start up?

ohhhh i see wat youre saying... ok first test the two pins on the distributor connector; C and D
then test C and E, where e is the coil output shaft is what im gonna call it. if you look at the dist. when the cap is off theres a long and skinny shaft about 1 1/2 inch long with a copper tip, that tip is point E.

ok, cool. I checked the coil and it has 100,000 ohms of resistance. The spec for the coil is 26,000 or so. So it looks like I'm gonna have to replace the distributor.

The coil has a primary and secondary coil that can be tested.

Primary should be between 1-3ohm or maybe even less.
Secondary should be between 6000-30000ohms.

-To test primary go between coil (+) and coil (-).
-To test secondary test between coil (+) and the coil output that goes to the distributor.
