Throwing parts at it isn't the way to go. In the past, I've had inactive codes point me in the right direction, no lite.
Evidently, you have no Schrader valve on this vehicle. There is a kit you can use to tee into supply line, has the proper connectors. If your going to work on your own vehicle, you certainly need to be able to check your fuel pressure.
Also, check the vacuum line at the pressure regulator. The pressure regulator is on the end of fuel rail. Take the line loose, if gas in the line, fuel regulator is faulty.
As far as the coolant temp sensor, no way from here can I be sure it is faulty? Should be located on the end of engine, the end is opposite from the drive belt end. The drive belt end is the front.
