what will a bad throttle position sensor do on a 1989 351W
My father in law has a 1989 f150 351w and it does not run very often. He went to crank it up and it sputtered and ran very bad. He thought it was the cap and rotor, so he replaced them. Now it will not fire up or even try to start. New plugs and wires are next, but I don't see how all of them would have gone bad at the same time. I checked all the obvious stuff like firing order and the timing and it looks good. The fuel rail has good pressure and all fuses are good. All connections look good. Spark looks a little weak. This ignition has the module on the dizzy and all the Haynes manual checks come out good. I ran the codes and it shows a #53, TP sensor out of range. If this is bad could it keep the fuel from injecting? I doubt it, but figured it was worth a try.
