Answer
Jesse,
What the best thing to do is see what the fuel pressure is when cranking and also if you have spark. That way you sort of have a direction to follow. Depending on the year and what fuel system the car has under the cap maybe nothing or a Hall Effect switch. If there is a three prong electrical connection to the dist then it's a Hall Switch. The ignition control unit is mounted along side the steering column inside the car. Is the fuel pump running when you try to start? If not bad relay, pump. If it is running is the feed pump in the tank pumping?
