hard starts continue after getting injectors cleaned

Knowing one of my injectors were leaking i thought getting them cleaned would solve my hard starting issues. A lot of white smoke would also come out from the exhaust signifying that it was flooding. After I got them cleaned and reconditioned the white smoke disappeared but the car still had trouble starting. I changed my spark plugs a year ago and barely drove the FC 1000 miles. It only has problems starting when its cold. I don't think one of the coils could be going bad because the car is really responsive.

any ideas?

Check the signal from the water temp sensor at the ECU. If the plug is off, or you have a poor connection cold starts can become difficult. A failing sensor can cause similar results, since it is used to determine the cranking fuel amount.

found out it was a loose wire on my water thermo temp. the plastic part that snaps into the sensor broke so the only thing keeping it together is the 2 clamp looking wires clamping onto the sensor. im pretty sure it gets loose when it vibrates but it never falls off. is soldering it a good idea?

Try looking Online for an injector place.
They would have a Pigtail with that Connector piece that attaches to your Sender.
Buy that Pigtail,solder the two wires into your harness and you are Golden.

An injector clip for a low impedance injector will be the same shape/size and have a centered groove for the tab. The BAC uses the same kind of plug too.
