hard start after sitting
Hard start after sitting overnight. It cranks fine, but, struggles to fire and sputters for a
second. After it starts it runs and starts again fine. I cleaned out the AIC valve and it
idles much better but didn't help the hard start problem. Thx
Try turning the key to "On" and wait a few seconds for the fuel pump to run and then turn off. Turn the key to off and back to "On" again. That will pressurize the fuel rail. It could be that your fuel pressure regulator is letting fuel drain back to the tank over night. The engine needs a rich mixture to start up and if the fuel pressure is low at start, the mixture is not as rich.
