90 Cutlass Ciera 3.3L

I have a 90 Cutlass Ciera 3.3L V6 that will not start after being parked overnight in foggy, rainy or snowing conditions. I have replaced fuel filter and had a scan check that did not show any codes. Any tips greatly appreciated.

Welcome to AF! Try this, buy a tub of dielectric grease and coat the coil wire terminals with it and reinstall the wires, do the same thing with the plugs by pulling each one and putting some in the boots and reinstalling them. Finally, under the coils there is an ignition module, pull each coil and put a little of the grease where the contacts go into the back of the coil. This should take care of the starting problem. (You may also want to check the connections to the ignition module and crank position sensor to make sure they are tight.)
