Hoping someone can help me. I have a 2001 Eddie Bauer Expedition with 158,+++ miles. It's been sitting a couple months decided yesterday to put it up for sale. Now it cranks but won't start with a new battery. I've been reading about similar problems to mine and the original poster here. How can I tell if it's the key or the fuel pump? I've only ever had one key that starts it and I don't know how to check the voltage. I can usual fix things if I know what the problem is. Figuring out the problem is usually the hard part for me.
