I have a 2002 chevy s-10 pickup, 4.3 V6 vortec, 4 wheel drive. It has developed a crank-no start when it's wet outside. Snow, rain, even high humidity.
Things already done: cap/rotor/wires/plugs; coil; fuel pump (fuel psi between 45-55). There was an issue with the distributor being chewed up by the cam - cam gear was inspected and is supposed to be in good shape. A used distributor was installed by the local shop. Engine has 200,000 miles. I was told the timing chain is a bit stretched but there is no timing problem.
When it is running, it purrs like a kitten. Good power, smooth idle, no smoke and there is no engine codes generated by the crank-no start problem. I have power to the coil when it's happening, fuel in the system, even have a spark out of each cylinder wire but it still won't start.
Anybody out there have any idea? I think the car is possessed!
