I have a 88 F150 302 that starter went bad so I changed it. It started right up and ran great. The next day I went to drive it and it just cranks over but won't start. I changed the coil, dist. cap and rotor. It started up and ran again. Later that day went to drive it and justs cranks over and won't start. I have no spark at the plugs. Any ideas?

 

check all of the electrical connections for any thing that would look to be looses , burned , melted , sloppy fit ! also wiggle all the connections to see if you do get any spark and if you do get spark then you know you have a bad connection ! also check all the grounds !

 

i would check the coil wire for a lose connection in the dizzy cap and on the coil its self.
