Still Hard starting
Ok so I got my injectors cleaned last week and put them in the car yesterday. The car started right up, but now its trying to start but wont until I floor it. 
Could there just be a sensor or something thats out of adjustment? I would imagine that my TPS is out of whack because I have never done anything with it. Am I on the right track? Thanks in advance.

When is the last time the car had a full tuneup? Plugs, wires, etc?
Does it make decent compression?
A sensor to check is the ECT. If it's reading wrong, then the cold start enrichment won't be correct.

Well I replaced the plugs two weeks ago. I am getting spark. It seems to be loading up really bad. I have to deflood to get it to start. It's hard to start hot or cold. Once I do get it started it idles fine and runs smooth, but also seems to be lacking in power a little. I haven't compression tested it yet but I will try that and see if it is bad.
Also what is the ECT and where might I find it?

ECT = Engine Coolant Temp sensor. Check the FSM.
Low compression will cause hard starting, so before spinning your wheels looking for other causes, check compression.
Another common issue is leaking fuel injectors. They may need to be removed and professionally cleaned.
