My car cranks a little longer in the morning

Try this test. Get in turn the key "on", not to start, count to five slowly. Turn the key off. Now try to start the car. If it starts up real quick it is normal. What happens is that the fuel pressure bleeds off overnight and it takes a couple seconds for the pump to prime the system. Because the pressure bleeds off there can be some air that has to purge through the injectors before it starts. Now during "normal driving" the fuel pressure does not bleed off and the car starts almost instantly.

Thanks so much! I will try that later today and see what happens.

Forgot to mention that if your in a cold area it can also make it a bit more obvious because the battery being cold and the oil being cold make the engine turn over a bit slower.
