I have a 2006 Ford Expedition with 95,000 miles that has a crank but intermittent no start problem. When it does happen, it will eventually start after one to two tries. I don't have to wait to start it again and I don't have any problems while it is running. Two or three times in the past two months it will sputter out and die (even though I am pressing the gas pedal) right after starting. I'll crank it again and it starts just fine. I have no problems while driving at freeway speeds or around town.

I never had any check engine lights come on so I replaced the battery and the fuel filter. I finally got two codes and replaced the fuel pump driver module and the fuel rail pressure sensor. The codes went off after replacing these two parts. I can hear my fuel pump turn on every time I start the vehicle. I have even taken the entire fuse panel apart to check Relay 303 which is soldered into the circuit board. It is fine and so is every other fuse in the panel. Any suggestions?

 

if you figure it out let me know. I'm having the same problem on my 02 f-150.

 

Can't hurt and clean maf with maf cleaner, not much to go on here .

 

Try this...turn the key to ON then OFF, then ON then OFF, then ON then start. If it starts right up and runs the check valve in the fuel pump assembly is leaking.
