Won't Start

I got into my great little 99 Frontier this morning and the thing would not start. It cranked just fine, just would never turn over. We have had wet weather the last couple of days and I have noticed before when the weather is wet and I have not driven the car for a day or longer it had had problems starting, but it has always gone ahead and started and after it warmed up a bit ran great. My inkling is that the moisture has efeected the fuel filter or something that is causing the problem. ANy suggestions???

thanks

more likely damp distributor cap..

There used to be a spray that coated the cap and wires to cure this dampness trouble. I don't know if it is still around. Most parts stores sold it when I was a kid.
