I have a 2000 Ford F150.It starts up every morning after driving it will not start till next day.It is a 4.6 motor what can I do to fix this situation? It is weird it will start up for me when I get in it in the morning.Drive it to work, shut it off and it will not restart until the next day.Sometimes I could Bang on the dash and it would start.But now that does not work, I did notice when it's warmer outside.It happens more often.

 

How did you discover banging on the dash would help get it started and where on the dash did you bang it?
