I have an '05 century. 120k miles. It starts perfect when cold. Sometimes when it is warm it takes 5 or 6 times cranking to start. New wires, plugs, pcv, air filter, and fuel filter at 100k. Fuel pressure builds the second the key is turned to acc. After the 1st or second cranking it will stutter but not start. I noticed that if i only turn the key back to acc it will not start at all no matter how many times it cranks. I have to turn the key all the way off between attempts. After 5 or 6 tries it will start. Any thoughts or tests?
