I just changed out my water pump and harmonic balancer with new units today and got everything back together and now my car won't start up. It cranks over, but that's all. Anyone have any ideas??

Wow. It could literally be a hundred different things. We need to know more to assist diagnosis. Go back over everthing. Check & make sure you connected everything back properly. Is it getting spark? Fuel?
Justin is right - go over everything you touched during that work. That is pretty academic work, and really I cant think of a lot that you could have disconnected which would not be obvious, and that would keep it from catching.
Did you disconnect anything to be able to bump the motor over w/o it starting? Could you have forgotten to reattach/re-enable that component (a coil lead, etc)?
If not, determine if you are missing fuel or spark or whatever and go from there.
good luck.

Yeah, I checked all my connections and they're all good. Could it be the timing?? I mean, the balancer is notched, so is it even possible for me to get it out of wack? I was thinking it might be my accell ignition, so I'm gonna bypass that this morning and see if that works too. I wouldn't think my ignition or fuel pump would have just died on me sitting the past few days, but we've all seen stranger things. Also, I had overheated the engine before the swaps because my water pump and radiator decided they were gonna go out at the same time on me while driving down the freeway, would that do anything?

Check the simple things first. Make sure you have spark. Listen for the fuel pump by turning the key to the "on" position (but don't turn it over). If you hear the pump, make sure you have fuel pressure building up. The simple way to check that is at the schrader <sp?> valve. If you have spark and hear the fuel pump kicking on, check the plugs. Could they have gotten fouled up from the overheating?
If it doesn't start it's one of three things: no fuel, no spark or no compression. I'm sure you know that, but sometimes it helps to hear the obvious. Good luck!

Ok, I'm a total moron, one of my fuses was blown so my fuel pump wasn't turning on, which I should have known but I totally spaced looking at my fuel pressure gauge. 
Crap thing is though, everything is back together and when I took it for a test drive it started to overheat after about 4/5 miles(It was around 115 today too).....I'm thinking it's because I don't have a thermostat in it right now because I didn't have a new one to put in so I just left it out. I picked up one while I was out running arrands earlier and I'm gonna go install it in a little bit....but if that doesn't fix it....anyone have any ideas why it might be overheating after a brand new radiator, water pump and thermostat?

If it is still overheating, your next bit would be to see if you high speed fan is working. Our fans have two speeds, low-high. It is pretty common for the high speed fan to not be functional, or you may even have a dead ccrm. Thats the little box hanging off the bracket behind your coolant overflow. Just in case you didn't know. Quick test would be to kick on your AC and see if your fan comes on with it.
As an aside, does the high speed fan always come on with A/C? My low speed fan comes on with A/C. 
I have seen people post this and never knew for sure. Then again, I have never let the high speed fan come on by itself, so I am not totally sure.
in addition to Shane's wise advice, one can let the computer cycle the fans during a code retrieval session.
Good luck.

Actually, that may be true. I have a custom tune that kicks on the high speed fan even when it should be low speed. I had no use for the low speed. Don't even see why there is a low speed on these cars to be honest. My last post be incorrect as far as the high speed with the AC. I would still look into the high speed issue though. Very common with these cars. I went through 3 fans in 110k on my 95GT........Good call JT-
Actually Shane, my car might be at fault. I keep an eye peeled on threads about people's observations with regard to A/C and fan speed, and your info falls into the high majority of what I have read (ergo I think my car is not right). I just have not found the info explicitly online or in the factory shop manual (it would not be my first wild goose chase).....LoudToy958 said:
The high speed engages via the switch and the high-speed fan connector has a light 'charring'
going on (connectors are still sound). I just did not know if I had a definate issue (I am not sure I would want high speed on with A/C, as that would definately fry the high speed connector [or more], I think). I am not all that impressed with these fans (fox guys hold them in pretty high regard). A Viper fan might be my next one.
As always, I appreciate your post and thoughts Shane.
Ok, it's still overheating after a few miles and I put a 180 degree performance t-stat in it. As soon as it started getting hot though I pulled over and popped the hood......fan wasn't running at all, so looks like I get to order a new one of those. I know what the ccrm box is...but what's it actually stand for?? lol, I've never really cared enough to inquire, but now that my car is sucking a lot I'm interested incase I decide on buying a new one just in case. Thanks guys.
