Prolonged cranking at times. Cold start morning is great starts yup runs very good. When it's all warmed up at operating temperature I park the car and leave for 10 minutes or so when I get inside the cart to start it. It cranks and doesn't start so I turn the key back and cycle the key back and forward 3 times without cranking. I listen for the fuel pump and wait between key cycles for pump to stop. Then it starts right up and runs super good! this happening 5 out 10 times getting more often otherwise runs and drive great. Never any codes or hick ups from engine. Nothing in computer memory at all.


Fuel pressure is running at between 53psi to 58psi normal. On shutoff the fuel pressure runs down to nothing in 20 seconds. most cars should hold 35 pound's in the system I can't get a consensus on the static fuel pressure = the pressure exerted by a fluid that is not moving or flowing.
