Re: i have a 97 camaro v6 its hard to start after it sets...
Almost guaranteed this is an injector problem. Its not uncommon for these to leak down, which means they sit there and drip fuel into the intake runners, flooding the engine. You should be able to buy these used on EBAY for fairly cheap. They are also fairly easy to change.

What exactly do you mean is there No fuel pressure please try and rephrase your question to a whole one. If you have no fuel pressure check your fuel pump see if you are getting any fuel if not it could be a fuse or it could be that you need a new fuel pump. Do you have vapor lock have you tried putting some fuel or ether in your cylinders or fuel injection and seeing if it starts if its vapor lock it could very well break it once it starts. You don't give any information so it is hard to give you any kind of details
One way would be to hook a fuel pressure gauge up to the rail and trigger each injector to see if fuel pressure drops. If one is clogged up you should be getting a cylinder miss code from the computer.
Need to verify fuel pressure at the injector rail with the engine cranking and with the key on and engine off. Specification is 55 - 61psi. The pressure should build with one cycle of the key. If the pressure is slow to build up there may be a restriction in the system between the pump and fuel rail .
The system should hold pressure without leaking down. If it leaks down there is a problem. If all is good there Checking for a good blue spark at several plugs to verify the ignition system is working ok. A vacuum leak could also cause a hard start issue.
A bad pick up coil or weak crank sensor can cause hard start issues also.
Sounds like you may have a leaky injector which is both leaking fuel into one of the cylinders, and bleeding down any fuel rail pressure. Extra fuel makes it hard to start, loss of rail pressure takes a few seconds for fuel pump to build pressure back up.
