Answer:

Remove the distributor cap and inspect it for cracks on the inside, remove the rotor and do the same, check for burned spots or cracks then remove the plastic cover over the coil, carefully inspect the coil for cracks on top also look underneath on the bottom side of the coil for any signs of arcing to ground, this is common on these distributors so I think you will find the problem there

How To Repair/Check Fuses

There are two ways to check fuses. The first is the good old fashion way of removing each fuse and visually inspecting each fuse. It's time consuming but effective. And the other way that is much faster and easier, but you need a "test light" before you can begin. Turn the key to the "on" position (do not start), ground your test light lead to a good ground source, like a metal brace under the dash, seat mount bolt or under hood brace. Then lightly touch the service port at the top of the fuse on both sides. If the test light illuminates on both sides of the fuse, the fuse is ok and working properly. If the fuse lights the test light on one side it is blown and needs to be replaced.

Coolant Leak

Introduction
There are a number of things that can go wrong with your car's cooling system, causing the engine to run warmer than it should. The following is a list of things that are easily checked at home by the do-it-yourselfer, and can always add to your knowledge of cars in general.

Instructions
Difficulty: Moderate
Things You'll Need
Radiator Sealant
Antifreeze
Water
Telephones
Steps:

1
Step One
Understand that overheating problems may be caused by a low coolant level.
2
Step Two
Check the coolant level at the radiator overflow/plastic coolant reservoir tank to see if you're low on coolant (see "How to Check Your Car's Coolant Level," under Related eHows). Add if necessary.
3
Step Three
Open the radiator cap and look inside the radiator when the engine is cold.
4
Step Four
Fill the radiator with antifreeze or water if it's empty, and close the cap.
5
Step Five
Look at both the lower and upper radiator hoses located at the top and bottom of the radiator on the back side and held by hose clamps. Make sure the hoses are securely clamped to the radiator and aren't leaking.
6
Step Six
Touch both the upper and lower radiator hoses when the engine is warm and the car turned off. They should both be warm. If one is cold, you may have a thermostat that's stuck closed.
7
Step Seven
Use the palm of your hand to feel the outside of the radiator from top to bottom when the engine is warm and the car turned off. It should be warm to the touch evenly throughout. If there's a cold section, you may have a radiator that's internally blocked.
8
Step Eight
Check under the car, inspect the radiator and look around the engine compartment for telltale signs of a coolant leak: Coolant is greenish, slippery and sweet-smelling.
9
Step Nine
Visit your mechanic if you know there's a leak but can't find it. A mechanic can detect a slow or small coolant leak by pressurizing the cooling system.
