My 92 F150 5.0 liter v8 has difficulty starting when it is very damp outside or it has been rained on and sat for a while. It turns over but does not start. Does anyone have any tips to repair this? I am guessing it has something to do with the electrical.

Thank you

 

Can't believe 40 people looked at this post and had no input. I put new plugs, wires, distributor, and rotor in and it appears to run better we will have to see what happens after sitting in the rain.
