The pick up was just overhauld and a week after just shut down and never started again. Changed every sensor, pick up coil, checked every splice connections and continuity and everything is alright, fuel pump works fine. Replaced the pcm. But doesnt start. It just dont give signal to the sensors. Dont know what else to do.

Check your asd relay under hood first it may be corroded or making bad contact. Then check all fuses as you mayhave blown one going to ecm

Check fuse D in pdc and fuse 13 in truck as they both power asd relay and may be killing power to the ecm. Other than that I can't think of anything else. If you get power from coil wire to dist then it may be a rotor/dist cap. Also check ohms of pick up coil in dist.

Coil, Dist cap and pick up coil in dist are new. But cant get spark. The wire that give energy to the ecm pin 3 is good but the pcm does not give signal to the sensors.

I have no further suggestions or comments unless it's an ignition switch problem.

Ok, I have checked the ignition switch and it seems to be working fine but I will change it anyway thank you for the suggestion.
While checking the dash lights the left side of the dashboard does not work. Only the oil light turn on when I switch on the car and while cranking it turn off. The right signal light works too. But the left one does not, the check engine light, headlights light, handbrake does not work either. That means there is a wiring problem right?
