That sounds like a faulty ignition module located inside of the distributor.

1993 honda prelude starts fine in dry weather but in wet weather it just cranks.


Sounds like moisture in the distributor cap to me. I would definitely start there first.

It could be the ignition module or brain box, but I doubt it.
Your complaint sounds more like weak spark plug wires and dist cap. Have you inspected or replaced them yet ?

Before you replace the injectors have them do an injector balance test. Normally wet weather does not effect fuel system. Sounds more like you have a crank or cam sensor acting up.

98 k 1500 wont start when its rainy or snowing turns over rough and and act like it wants to start . after it dries out it starts but still starts rough. after i get it running it starts fine until it...


As for the rough or slow cranking when you have wet weather it sounds like the starter brushes and or some other problems inside of the starter. You can pull that and take it to most parts stores and they can check it for you. As for the ignition problem I would say to go ahead and replace the wires and plugs as well making sure to by top of the line 8mm wires A/C Delco is a great brand. I don't know where you have been buying your caps and rotors but I have seen this problem happen when people buy these parts from AutoZone so if that is where you are getting yours I would recommend you go to Napa auto parts or Oreilys. And again buy only top of the line, it cost more but they last so much longer. Good luck.

Start with a set of plug wires, since it seems to happen in the wet weather, and pick up a can of wd40 or wiredry to keep in the truck.Hope this helps.
Good luck.

Car sputters at start up in wet or damp weather


spray your distributor wires and cap with silicone spray. If this does not work you will have to replace distributor cap as it will have a hair line crack in it.

1500 chevy suburban 5.7 won't start in rain


Time for a complete tune up, this time put a distributor cap on too, plugs wires cap rotor, and use quality parts. what you got here is condensation getting under dist. cap most likely because cap has a hairline crack in it.
