    could be leaking injector,fuel pressure regulator or fuel pump providing there are no external leaks check fuel pressure after shut off and again 2 hrs later (if car smokes when hard to start then most likely leaking injectors)

Look for something draining the battery overnight such as a light or some accessory that should turn off after a delay. One of our Ford experts may be able to pinpoint the problem with your Expedition

2003 Ford Expedition is hard to start. I takes two to four turns of the key to get the engine to fire.


Could be fuel pressure loss.
The fuel pump is supposed to hold pressure when the engine stops.
If it falls to zero, you would have to cycle the fuel pump relay a few times to get it back up to start.
I would check the fuel pressure first.

I have a 2003 ford expedition. Recently, the vehicle would shut off completely at random times...you could be driving 10min or 2 hours, it would not restart immediately after wards, you would have to let...


Check out the fuel pump on an oscillscope
Check the fuel pressure at the fuel rail
Need a clean fuel filter

Check TPS with a scope

I say scope because it will show you
quickly what is going on,where as a
volt meter only gives you numbers (volts)

Scope the O2 Sensors also or replace if
at 100,000 miles (front 2 only)

Spray throttle plate and MAF Sensor
with the CRC Products for those two

When attempting to start it takes more than 1attempt


OK. Do you mean that the start won't turn over when hot( in which case the starter is the cause), or do you mean that the starter turns it over but the engine doesn't run immediately (in which case an engine analysis and code reading may be required)?

Truck won't start, but after ride on tow truck starts right up, please help?!


Typically when the fuel pump goes it is gone. Have you ever changed the fuel filter? On my 2000 expedition it is inside the frame on the drivers side about midway. Try this first, it is cheaper and easier than a fuel pump. Takes about 10 minutes.
