Why Does My Engine Crank Excessively and Hard to Start?

Very true, having multiple issues at the same time can make things very interesting to work with. Especially if they are related items.

Awesome! I have an older expedition myself and I replaced several parts along with the fuel pump at 150,000 as a preventative measure because I see them fail at roughly the same mileage all the time at my dealership! I'm glad you got it resolved!

Hi:
This could be caused by many things, Idle air control, throttle position sensor. What I recommend is to have the computer scanned at a nationally recognized parts store. Most will do it for free, and it will direct us as what needs repaired.

Let me know what you find.

Have you checked your idle air control valve?

Has the check engine light come on? My first guess is a bad temp sensor. The sensor tells the computer what the outside temp is and the engine coolant temp is. From that, the computer determines how rich or lean to make the fuel mixture.

However, what I really need to know is the following. When this happens, have you ever checked for spark and fuel to the engine when it doesn't start? Chances are one is missing and I need to know which it is.

Here is a how to for checking both:

When this happens, check both and let me know what you find.
