My 2000 CMC Safari will just turn off while i am driving in the rain. It is also hard to start some time in the rain. Can anyone help.

    Sorry, mine did the same thing. It only got worse. Good fuel pressure. New ground wires... Good coil. New distributor. now it won't even run. Looking forward to the answer you get.

    97 Astro doing the same thing. I'm pretty sure it's the ignition wires. Just ordered new ones, I'll update you after I install them.

    My van shut off in the rain also. It was the ignition coil shorting out to ground. I found the problem by misting the whole area with a spray bottle while the engine was running and the dog house removed. The tower had a hairline crack.

    I know this thread is old but FYI, I had a 2000 Astro and it took my mechanic a week to find the problem(van shut off in the rain, stumbled in damp weather) He had bench tested the coil it was fine but a simple misting with a spray bottle told the tale. The coil had a hairline crack and would arc to ground in damp weather when it was dry no issues

    I have a 97 Astro and will try the coil but so many people have done that without success.  When it’s damp, foggy or raining the engine stumbles, sei light flashes, strong fuel odor in cabin and white exhaust from tail pipe. It has burned up one cat. I did the fuel injection. Also wonder if leaking power steering fluid is killing an o2 sensor wire.  Fixed the steering pump in spring.  Sunny day, a water truck spraying road for construction dust caused misfire. Always # 1 cylinder..   A mechanic charged me $637 to Time it and put a new distributor cap on it only to have it fail in the first rain of the year.  I have drill holes and the distributor too .
