Mike, did you mark up your pullies/sprockets? A common thing to get wrong is to have the pump timed 180 out. I don't know your engine but if it's a real pig to get at the timing sprocket and you suspect 180 out, it is possible to swap the injector pipes at the pump.

If you are completely lost, slacken all the injector pipes at the pump or injectors - whichever is easier, remove cylinder one injector, turn the engine so that it is coming up to compression on cylinder one - you can feel this through the injector hole and watch to see which pump outlet delivers fuel. If it's the wrong cylinder, work from there. If it's just completely the wrong timing then work from there also.

I've usually found that if its just a timing problem and not wildly out, the engine shows signs of trying to start but just cant pick up and run. If it's 180 out, you get fek all.

The pump will be rotating at half the speed of the engine. But I guess you know that.
