Do you have the little Schrader valve at the end of the fuel rail that you can check to see if there is fuel behind the injectors ready to go and it is at pressure?

Depending on results check power to pump, while diagnosing mine I made a special lead to take power from lighter to fuel pump! - it worked for me as I could then hear the pump wering away and test that all else was ok then fixed firing for pump!

Also see if you can work out a way of testing the square wave output of the CPS (not easy with out a scope!)

good luck
