I Have an 86 4runner with a 22RE motor in it. It runs really well most of the time, but whenever it rains, it doesn't want to run. It seems like it isn't getting fuel. Some things I have done is: Plugs, wires, cap, rotor, made sure fuel was in the tank, and checked all fuses. What it does, is when I go to start it, the truck starts, runs for about a second or less then dies, that is why I think it has something to do with fuel. BTW, good spark at all plugs. Any help would be greatly appreciated.

 

hmmmm...on my volvo the negative ground on the chassis for the battery had a poor connection and my car would do the same thing in wet conditions
