89 F250 5.8 liter won't start
In run position spark at coil but when
cranking no spark to distributor. Have
replaced coil.
Maybe something wrong with ignition switch? Note the diagram. See the start ignition on left side. If you track the wires back to ignition switch, one says crank position, the other says run position, goes to same place. I'd check those wire colors for voltage with key in proper position. I'd hate to see you replace something and it not fix the problem? Do testing first. good luck
do you have primary voltage to ignition coil, with key in the run and crank position both? Just a thought.
Battery has a full charge and connections all good? I should have mentioned that first.
