I have an '03 S-10, 4 banger. It starts up and runs 100% of the time, except for after it has sat out all night when it's been raining. I don't believe it has a distributor cap, so is it just the plug wires? Thanks for the help.
I changed the wires around 40k miles ago, but it has developed a problem starting after heavy rains, or snow around when parked outside over night. It starts up perfectly hot or cold, as long as there is no rain or snow over night.
wires or coil pack. possibly crank sensor.
