I have 97 f350 bucket truck and it seems everytime it is damp out it does not want to start. I am getting fuel and starter cranking but no spark. My friend gave me a spare spark box out of a f150 to see if that was problem but i cant even locate under the hood. Distrubutor is dry when i put my finger inside bowl. Not sure what to do need truck for work tomorrow. Any ideas on what to look for it has a 460. Thanks Jay

 

Have you checked all the fuses for good connections. If any moisture managed to get into the fuse panel it can drive you nuts with intermittent connections.
