— i have a 2015 f150 lariat 3. 5l eco boost, i changed the spark plugs and ignition coils and now the truck will not start it cranks but won’t start….

I read somewhere that two original or official ford.

So again you didnt get a code for crank sensor. you just whittled it.

Recommended for you

Drove it 10 miles and parked it.

— no codes but all of sudden crank but no start nor want to start.

Turned out to be the 20 amp fuse for position 27 (fuel pump relay power).

— i've seen starters that have the starter drive kick out but have a flat spot on the armature and won't spin.

It will crank over and sputter but not fire.

— '14 3. 7l, 130k, no codes, no problems.

I have checked fuel pump fuses,.

I may need to look into this crank sensor?!

Stopped to fuel up, tried to restart and nothing.

I have verified that there is spark at least at the first coil.

Sometimes the bendix kicking in and out provides just enough.

And, when a relay clicks, that.
