my 4.6 Triton has no fire after I changed the engine. I put new crank sensor in it and don't see any missing ground wires but I'm not sure if I missed one or not could there be another problem as far as why it will not fire it ran before we took the motor out

 

go through and check everything again and again

 

Sure, - most of the time you just need to purge the fuel rail..at least once.

That's IF you have everything reconnected correctly.
