Hi everyone, I'm having trouble with my expedition 1997 5.4, i was doing some maintenance on the motor that consisted on replacing the admission with a new one, after installing it and connected all cables i tried to give it a run but only cranks and no start.

I connected my scan tool to check what happened but it said error when trying to enter the computer, the fuel pump also isn't working.

Some things I tried are testing my fuses and relays, checking grounds, see if the anti thief was triggered and the fuel reset button so far.

This is my 1st time posting here so I'm sorry if i put this where it doesn't go.

Also trying my best with English because I'm from Chile.

Thanks to everyone that will try to help me.

P.D. also I noticed that my 175a megafuse was shorting in the chassis, y repaired that but I don't know what problems may have caused.
