2003 f150 5.4 4x4 fails on its face when I put it in gear and there’s all kinds of codes. Any suggestions ware to start looking thanks just pulled the codes there is a lot of them they are p1747 p0755 p0750 p0743 p0135 p0145 p0155 p0161 p1131 p1151 p0171 cleared the codes once but came back after after a little bit so im asking for any help in tracking down the problem So I replace the computer and it still doing the same thing and I’ve checked all the fuses everything seems to be fine there so I’m thinking it’s got to be a bad connector or wire burnt into something like that

 

Check the connector at the firewall for the main wiring harness. Also check fuses.
