First thing in the morning the car will not start. It is not the battery. It is getting power as it tries to crank, but acts as though it's not getting enough fuel or fire. If you pour a little gas in the throttle body it will start and continue to start all day with no issue. The fuel pump was changed about 5 years ago, the fuel filter was changed yesterday, the battery is strong, the idle air control motor was changed 3 days ago (for the second time).

Thanks -- we'll try that. If it is a pressure issue does that mean that the fuel pump needs replacing again? Don't understand why it only does it first thing and then no further problem until the next morning. It only started when it got cold.
