So, when my car sits for a set amount of time (six, seven hours) it has a rough time starting and I have to hold down the pedal to build back up the gas pressure.

How exactly do you test for these things? I've replaced a hose leading straight to the engine from the fuel system that had a cut in it, and I will say that that particular piece that connects the hose to the engine does seem loose but I don't have the experience to know if that is the issue.

Maybe also someone could suggest a bonding agent for that?

Pull your injectors out and see if they are clogged. Though this sounds more like an airflow issue to me. Fuel pressure problems will generally cause the engine to lean out towards the higher RPMs.

When you turn the ignition on can you hear the fuel pump priming?

Yes, and in fact I put a new fuel pump in it a while back.

I wouldn't doubt it on the air flow part, though. My engine does seem to cough and sputter quite a bit when getting started.

Alright, so let's say that there was a clog some where in my exhaust system- would it cause this? Namely, junk or water that has gotten into my catalytic converter.

Holding down your gas peddle while trying to start the engine does not add fuel. Fuel injected vehicles do not work like carbureted ones.

Yes a clog in your cat can cause a rough start but you would also have no power after the vehicle was running. Going up hills this lack of power would be very noticeable. Your catalytic converter would probably start to glow red hot if it were clogged that badly.

I would take a guess that you may have an ignition issue. When was the last time you changed your distributor cap, rotor, spark plug wires and spark plugs? It could also be your ignitor or coil starting to go bad. There are tests that you can perform to check the coil and ignitor. Don't just go replacing them.
