94 ranger 3.0 Cranks but won't fire
I broke down in the middle the road car just died. I thought it could be the alternator not charging the battery so I replaced that. That didn't work. So I checked for spark and it was week so I replaced the coil the distributor cap rotor and the plugs. I don't know what to do I changed everything I can think of and I'm stumped somebody help please.
