Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is XXXXX XXXXX i will do my best to help you.
how do you know the coil was bad?????
I plugged a screwdriver into the coil wire and tried to arc it against the spark plug and it didn't work. Does this tell you anything? I just don't want to short it out.
Ok. There is power. on the beige/yellow line. same voltage as the battery.
But, when he took the cap off the distributor the "rotor"-round thing on top- is not spinning. He thinks that may be the problem. Could that be it?
If so is this something he could fix himself? and is it worth it. thanks.
ok see if it is spinning while the engine is cranking. ???
can he spin the rotor by hand????? the distributor may be broken or the timing chain might be broken.
ok you need to remove the distributor and cehk for the teeth on the bottom to make sure theyre not ground off. heres how it looks. its a general ford picture so dont worry if its not exactly like yours but they all function the same.
you want to make sure that when you turn the rotor or the gear here at the bottom that the rotor and gear turn together, they are connected on the same shaft so they should be identical when turning. the part numbered 12171 is what makes the coild fire when the engine is turning. so if the shaft is not turning then if wont allow the coil to fire.
well you did all the grunt work. only 2 things will cause your problem of a rotor not turning.
1. a worn gear on the bottom of the distributor and broken distributor shaft
2. the timing chain on the engine is so loose it will not turn the camshaft (thats what the gear from the distributor turn with) and rotate the rotor. so you have a great deal of diagnosis done all you need is someone to remove the distributor and see what is going on in there.
oh gee thanks! you are too kind! :) I am sorry it didnt come through though... we asked you a bunch of dumb questions! thanks for all your help and maybe if he doesn't give up on this damn truck, i will give up on him and take you up on your offer! live and learn?? :)
