I have a 2000 ford taurus 3.0 will start but not stay running unless gas is applied. ????

when you hold the accelerator does the vehicle stay running? if so the problem is in ithe IAC idle air control motor, take a small screw driver and using the handle tap the iac motor and usualy the motor will kick in and the vehicle will run fine then if the problem is rectified replace the IAC

SOURCE: 2000 dondge durango Code 201 and 455

A code p0455 most likely means one or more of the following has happened:
-A loose or improperly affixed gas cap
-A non-conforming gas cap (i.e. not factory/original brand)
-Other leak or damaged piece in EVAP system

With a p0455, the most common repair is to:
-Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
-Otherwise, replace the gas cap, and/or
-Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary

As for P0201, the causes could be any of the following:
-Bad injector. This is usually the cause of this code but doesn't rule out the possibility of one of the other causes
-Open in the wiring to the injector
-Short in the wiring to the injector
-Bad PCM

Possible Solutions:

1. First, using a DVOM check the resistance of the injector. If it isn't within specs, then replace the injector.
2. Check for voltage at the fuel injector connector. It should have 10 volts or more.
3. Visually check the connector for damage or broken wires.
4. Visually check the injector for damage.
5. If you have access to an injector tester, activate the injector and see if it operates. If the injector operates, then you likely have either an open in the wiring, or a blocked injector. If you do not have access to a tester, swap the injector with another one and see if the code changes. If the code changes, then change the injector.
6. At the PCM, remove the driver wire from the PCM connector and Ground the wire. (Make sure you have the correct wire. If you're not sure, do not attempt) The injector should activate
7. Replace the injector

Look on the throttle body for a little cylinder with an electrical connector on it. Use the handle of screwdriver to give that a few whacks while someone starts the engine after it starts, give a few more whacks. Engine running now? Replace the Intake Air Control motor. or IAC.

replace the gas filter just follow the gas line of the carb it should be easy to find
