96 chevy 2500 heavy duty won't start when it rains
What is your question?
Please forgive a seemingly stupid question. I am a grandmother and not mechanically inclined. My truck would not start when it is high humidity. It turns over but won't catch and when I turn off the key almost starts an then shudders with a loud clang in the motor. A retired mechanic told me a few years ago it was a module that needed replacing. I picked it up and took it to a friend to be installed. He did not believe that the module was a problem and showed me he had loosely installed it but left the old one hanging ( Between the carb and the firewall) so I could return the new part if it made no difference. It worked like a charm until a few years later when they both fell off. I want to pick up a new module but can't remember what it was called. Does anyone know what that module is?
What makes this problem better or worse?
high humidity

Hi There, thanks for responding Casey. I'm afraid I don't have either module. They probably fell off when I was picking up horse hay in the field. The truck starts like a dream when it is dry or minus 30 just refuses to when it is wet out. I remember the module was black and cube-shaped, about 2 1/2 inches on all sides. The man who replaced it was hit by a train and has severe memory problems now so he can't help either
Ok,
I would recommend taking it into a local shop, pointing out where the old parts were, and having them identify it for you. That will be much more helpful to you.
