Hey guys, so my expedition has been having trouble starting up. Usually after I driven it around for a few minutes and go to the store and come back. The car won't start till I crank it twice or keep cranking it. Please help. Thanks in advance.
Start on second crank

Your fuel pressure is dropping. You may need a new pump. Check the pressure with a gauge first.
I was hoping it wouldn't be that.

After you check fuel pressure post the results Keep in mind it could also be a problem with the fuel pump relay on the circuit board in the fuse box

The next time your drive like this and prepare to start the engine, turn the key to "run" but do not crank the engine. Turn it off and repeat. Then try to start the engine.
If it starts, it indicates the fuel pressure regulator is leaking pressure back into the fuel tank. By turning the key to "run" twice, you are enabling the fuel pump to pressurize the fuel rail before you try to start the engine.
After the engine starts - does it run smoothly or rough? If it starts and runs rough, it could indicate one or more fuel injectors are sticking open - allowing raw fuel into the engine when you shut off the engine. If it runs smooth, the problem is probably the fuel pressure regulator which is part of the fuel pump module.
249,000 I'm going to get the pressure at autozone this weekend.
