1988 3.9L won't start
 

Has a very weak spark at the coil wire.. replaced coil, coil wire, cap, rotor.. No luck.. I saw note of a cam pos. sensor. is that in the distrubitor circut? Any ides ? Thanks, Ted O.

If you have a weak spark my guess will be a bad power or ground wire. Or bad plug wires.

Power/grnd. is fine.. Again, what is in the circut for firing the coil ? Thanks...
