Cranks won't start No codes

06 f 150 160000 on it. I've changed the crank shaft and can shaft sensors the starter the fuel module and the spark plugs. I took fuel rail off and the injectors are dumping gas in a stream and one wasn't dumping nothing... Will they cause it not to start?? And what should I do next??

yes, they can flood the engine, do you have spark, would be on list to check at each coil. I'm still learning these, but 87-96 if you hold gas pedal to floor when starting, it keeps injectors from firing, when it is flooded, these may not do that, can try it.

Be very careful , injectors leaking or putting out stream is a very bad thing . Liquid in cly will hydro lock engine resulting in bent rods , holes in piston, fuel in crank case . Fluids can't be compressed something has to give . replace bad injectors with new not remans . Take plugs out and expel fluids out spark holes but the damage may be already done.
We advise laying fuel rails on dry newspaper with injectors in them turn key on none should leak . Around 130k to 150k put new ones in .Don't experiment with injectors unless you are very experienced .

Do you have ignition?...... Turn the key to ON, but not start.. THIEF light comes on for 3 seconds, computer recognizes key, then light goes off......... Does that happen ?

Took out fuel rail and it's dumping gas in a stream . I've cleaned it all out. Still same thing. After changing all those sensors should I reset the pcm.?? Still not getting any codes.

Check fuse #33 in the fuse panel behind the kick plate on the passenger side, if it blows you will get a crank no start situation. The circuit supplies power to the coils!
