Hello,
First you need to find out if you have spark. The fuel pump relay will not be energized if the control unit does not see a crank signal. Also the fuel injectors will not function as well. Have you checked for spark? If you have did you check at the coil wire going into to the distributor cap. Please advise. If you have confirmed spark the next thing I would do would be to clean the grounds on the head near the number 4 fuel injector because the control unit grounds there. Good Luck, Bernie at George Riggin Specialty Automotive
