Scotty my parents 2000 GMC Safari has a problem when you’re driving on the rain and you shut off the Engine the next day it will not start again I heard this is a common problem with GM we replaced the fuel pump crankshaft sensor spark plug and wires cap rotor Ignition coil with module and still nothingThere’s no spark or fuelOnce a couple days pass it will turn on again and work fine until the next rainy day starts to go bad again what could be the problem?

electronics are shorting out. Check ALL connections for corrosion inside first, especially computer and sensor wiring connectors

Thank you Scotty somebody told me that Corrosion might be the problem too thank you again👍
