02 ford expedition cranks but wont start.
I had to rebuild my 5.4 POS triton motor in my 02 ford expedition. Now it wont start. I have replaced the crank and cam position sensors, I tested all the fuses and fuel relay and pcm relay and pcm diode is new. I replaced all the wires on the engine wire harness and rang them all out and tested resistance- got .2 ohms. I tested fuel cut off switch and theres power past the switch. I get 12 volts at every coil pack and injector. the fuel pump comes on for 1.5 seconds when turned on. when its cranked over I only get 1 pulse flash from noid light at injector 1. if turned off then on again it will flash 1 time again. no pulses to coil packs. I cleaned the ground connections and all are tight. I tested the fuel pressure at the shrader valve on the fuel rail and got no pressure but the instructions on the fuel guage says the motor must be running to read any pressure?? I'm lost now and don't know where to look next. when I tried starting fluid it tried to fire for a second but wouldn't start. now even starting fluid wont do anything. Please help.
