First time I did an injection pump - felt the same way - scared the hell out of me! Patience and doublechecking everything is essential the first time until you get the hang of it. Then - before starting the car - I'd turn the motor over two complete revolutions by hand feeling for any unusual tight spots and then check the timing again before trying to start it. If you are off - you won't do any damage by hand turning as opposed to starter whipping. Good luck - and remember - what you will learn by doing it once - you will probably never use again - Murphy's Law!! As you can see from my signature below I have a few of cars to maintain (two kids plus wife's car)! But it is a lot cheaper than taking it out to get done!
