I just placed a new 5.4 triton v8 into a 2008 ford f150. I am having a fuel delivery issue with my injectors. the engine will fire if starting fluid is used, so i obviously have spark. I have a new crank sensor. I have 12volts at my injectors but no pulse. The only thing that isnt new are the 2 cam sensors. I am at a loss and it wont throw any codes. Can someone help with this plz

 

What is your THEFT light doing when you try and start the engine?

If it is fast-flashing, the anti-theft system has shut down the injectors (that's how it works on that truck).

 

if i turn the key on but dont start it than it stays lit for about 3 seconds and then goes out

 

if i crank the engine, the theft light stays dark
