Car is hard to start.

Car is hard to start.
Hello,
I just finished installing some used fuel injectors. The car started up right away at the first few starts. The car ran pretty well. I drove it around a couple of miles and parked it. The idle seemed kind of high so I adjusted the A.A.C. valve. Then, I turned off the car and went to start it a couple of hours later and now it is hard to start. I have to contantly crank the engine and push the gas to get it started. Once started a cloud of greyish smoke comes out of the exhaust and runs smooth. The only thing is that it idles around 1200 rpm. What could be the problem? I would like to hear your opinions. Thanks.

Do I need to adjust the TPS sensor when I put it back on? I am thinking that the TPS sensor is not adjusted and is causing the car from starting up. How would I have to adjust the TPS sensor?

How far did you adjust the AAC? Can you backtrack and reset it where it was? Perhaps the high idle was a quirk, and now the idle is set too low.

I did take the TPS sensor out. I guess it will need some adjusting.
This problem seems to be worse when the engine is hot. When it is cold, the engine starts right up but hesitates. I have to give it some gas, and then it will start to idle smoothly. It blows out a cloud of blackish smoke and idles at around 1200 rpm.
Does a improperly adjusted TPS cause this problem? I am not getting a check engine light but how about a bad oxygen sensor. Thanks.

Now the car does not start whether it is cold or hot. I started to crank the engine and the engine was getting flooded with fuel. So I took the fuel pump fuse out and ran the car and it started up. I then put the fuse back and it was running rough and idle down. It seems like the engine is getting fuel. Any ideas what could be the problem?

I had a leaking radiator and ended up fixing it. The problem is now gone. I guess the engine was getting hot but the ECU was thinking the engine was cold and flooded the engine making the car hard to start. Now, I just have to fix the rough idle when the engine is cold. Thanks.
