Your coolant temp sensor may be why It acts to enrich fuel like a choke.

    There are so many things that control the fuel at any given time. The 02 sensor constantly monitors the emmissions and in turn tells the computer control yo lean or enrich the fuel to control the emmissions This is what I call an efficiency sensor. As I said in my previous post, The issue is in the start portion of the engine. The coolant temp and intake air temp set the fuel sytem to enrich the fuel in order to start And it's the starting thats giving you trouble, not enough fuel. The gas pedal does not function like the gas pedals 30 yrs ago. The pedal only comes into play once the engine is started and all sensors report to the computer module Try this, turn on the ignition an wait 15- 20 seconds. Do not press the gas pedal as you crank the engineI would bet the engine starts with no help. Let me know and good luck.
