Not mentioned before, the air plate has to be down some or all the way before you will see fuel at the injectors. The plate should go down with some resistance and come back up freely (on it's own). If the valve in the fuel distributor is gummed up, it won't want to move down at all. DO NOT force it! Check for spray at the injectors with the pump relay jumpered and the air plate held down. Try to do this with the injector still hooked to it's fuel line. This will give an initial check of fuel pressure. It takes 70 lbs (I think) of pressure to open the injectors.
Edit, I'm sorry, I missed the post by Eugene about deflecting the air plate. Still, I recommend you remove the injector and check for fuel with it still hooked to the fuel distributor.

Good luck,
Paul
