No power to my coil

Take the coil wire off the distributor cap, hold close to engine ground/metal part. Have helper crank it while you watch for spark to jump from coil wire to ground. If you have spark, I believe the coil is ok. If no spark, check for primary voltage to positive side of coil, I believe it goes hot/voltage with the key on. You may also have to check the coil wire.

Did you visually check for spark at the plugs with engine cranking?

With wires disconnected from coil, you can do an ohms test between positive and negative side of coil, 1--2 ohms.

Can you do a little testing? If you don't have primary voltage at the coil, replacing the coil won't help.

If you want to replace coil without any testing, that's up to you, it your money. It might fix your problem?

The positive side of the coil, key on, dark blue wire. That circuit is fuse protected, fuse 13 in your fuse box. The voltage to the fuse comes from ignition switch.

Use a testlite on both sides of coil with key on, anything there?

It means you need a ballast resistor between the ignition switch and the coil

It probably has a ballast resistor-put the coil on and see what happens

You should have 12v to the positive side of the coil.

You need to use a volt meter to determine if there is power there.
