I am busy restoring a 1973 3.0 csi
Last week I wanted to start the enige but no succes. When turning the key over the engine turns over but wont start up. I also dont hear the relays kick in and also dont hear the electric fuel pum running. I have checked all the fuses and cant find any thing wrong with the relays. Has anybody got an Idee what it could be. You can answer here or mail me at

thanks guys
If you don't have a shop manual or something like a Haynes, Chilton, Autobooks or Clymer manual, you should. Most of those books have basic troubleshooting checklists that could at least narrow your diagnosis.
If I understand your post, the starter is turning the engine. You are also guessing that the fuel pump is not being energized because you do not hear the relays or the typical pump noise. If you have really checked all the fuses and related relays, what about voltage at the fuel pump relay (under the right rear passenger seat) and the pump itself? Hint: A volt-ohm meter could be very handy when testing circuits.
If you have voltage to the pump relay and the pump, look to the pump itself.
If you don't have a test meter and your pump has sat without use for a long time, I would test it directly with a 12V source. Original pumps have a tendency to seize, especially if allowed to sit dry (without fuel - to prevent rust). It might be easier to remove the pump and bench test it or, if you are so inclined, hot wire it directly to a battery with the pump installed. For safety reasons, I would think it makes more sense to test the pump out of the car.
If the pump checks out, there are several other things to check, including a a finicky ignition switch. If you haven't done so, try searching previous posts on the subject.
HTH and good luck!
