My engine won't start when the weather is humid or when it rains. I changed the fuel pump, distributor, rotor and the main relay but i'm still having the problem. My next step is to change the coil, but i needed some advise on this, because i've already spent a decent amount of money on this and i don't want to buy the coil and still have the problem. If anyone has had this problem before get back to me.

 

It'd be a step in the right direction to change the coil.

 

Before you shell out even more money maybe you can have a mechanic look at it and tell you whats wrong.
