Question about Ford F-150
Problem list Checked follows as good. Battery , cables load tested , connections , starter relay and starter functions when isolated tested starting engine, replaced ignition switch and DTR, checked relays and fuses, PATS working verified with two separate keys. There is a constant 4.5 vdc in off postion, on postion, and battery crank postion. When removing the negative terminal there is 12vdc in the same positions when the S1 or signal terminal is read from the battery negative to communications wire that feeds the starter relay. What other possibilities could be suspect.
Ok it seems you isolated and checked the usual suspects and some that I wouldn't have looked at except one. Did you check the neutral safety switch and Alignment on your gears for the gearshift lever. If it is not aligned properly it may not be hitting the neutral safety switch when in neutral and park. Also if the switch has failed. It may not be allowing your system to start when you move the key to the start position. I'm also wondering if this model has a fusable link in the starter cable but you say that you've isolated and tested both the starter and the relay. So I would really suspect that neutral safety switch. Hope this helps.
