Truck won't start after maintenance Need help ASAP

[DOGO X]

After changing the motor oil and fuel filter, truck won't start. I did the 6 time 30 sec switch but nothing. The wrench emblem is display on the digital dash

Any idea?

There is a schrader valve at your fuel cooler, depress the pin while the fuel pump is on and see if fuel is coming out. This also helps purge air from the line.

I did it, it will start for a few second and the shut off

I'm guessing you don't have a way to read and post the code here? If all you did was change the oil/filter and the fuel filters, the only possible thing would be air in the fuel line. It may take more than the 6 times to purge all of the air.

Have you tried removing the cap on the engine mounted fuel filter to see how much air is trapped in there? I think someone had posted a while ago that they left that cap off, turned the key on (DO NOT START THE ENGINE), and had a buddy watch. When it filled up, they shut the key back off and put the lid back on. Maybe someone else can confirm that though.

Good luck... keep cycling that key if nothing else.

I've seen this one before; If it's not a motorcraft filter it swells & cuts off fuel flow. Put the old filter back in & see if it runs.

im purity sure that they have self bleeding fuel systems..next time you change the fuel filter just leave the key turned on for a mins or so..should do the trick just fine

the 6.4 requires the key to be cycled on and off as per the owners manual.

I read somewhere a Ford mechanic saying that they will put the engine
mounted fuel filter cap back on, but they won't tighten it all the way and then
they will cycle the key ( don't start the engine! ) and let some
fuel run out and then tighten up the cap. I'm not saying I recommend
this, just that it was written somewhere here a while back as a way
to purge the air ...

I just changed mine the other night. I've changed them twice. Each time I turn the key, I listen for the pump to purge the air. It lasts for 30 seconds ( I timed it). I cycle the key 7-8 times to be safe and I've never had a problem, knock on wood! Cycling the key is the key, per the manual. Just my two cents
