When a fuel pump goes out it would never start, no matter how many times you cranked it over.

1. Not enough pressure is built up when the pump primes
2. Not enough pressure is held
Pressure not being held can be something like a leaky injector as well.

I think that if the above ^ was going on with the fuel pump it would have more problems than a sluggish start, IE.....poor performance.........starting then dying......etc. At least I know what to look for if my fuel pump "starts" going bad.
If you are familiar with GM two speed fuel pumps, it will start to sound like it's always on high speed. Loud audible whine.

Having the same problem I am having this same problem on my 95 Z. I can't find the Ignition relay and Starter relay anywhere, Including my Chiltons manual. The car runs and accelerates great once it is started, but it always take 2-3 long cranks to get it started. I will check the fuel pressure today, but because there are no other symptoms, I really don't think that is it. Any help would be very appreciated.
