I swapped a 4 cylinder to a 5.0 got everything done, but now the car will not fire. I used a 302 from a lincoln so i used that firing order. I am getting gas to the motor and through the plugs, but it still will not turn over.
Confirm that the rotor points to #1 plug (front passenger side) when the piston as it TDC. Also, which Lincoln did you get the motor from? Town Car or Mark 7?
did you also make sure the injectors are plugged up in the H.O. order? and when you bring it to TDC make sure its on the compression stroke. edit: is it not turning over or is it turnig over and not firing? you stated both.
