Question about 1994 Ford Taurus
Based on the information that you have provided me, my attention is now centered on the ECT Sensor (Engine Coolant Temperature). This sensor provides information to the ECM to richen the fuel mixture on start up and also to lean out the mixture as the engine warms up. Very similar to the old fashioned choke in operation. A cold engine requires additional fuel to start, while a warm one does not. This matches your situation of a cold start versus a re-start and also explains why you are having to cycle the start sequence several times to fire the engine. Those cycles are finally providing enough fuel for start up.
Check with a local auto parts outlet to see about having the ECM read for a memory code related to the ECT. Most of the stores will now do this testing for free.
Let me know if this helps you out or not. Thanks.
