i could've sworn i replied? must've not went through. i don't think the cold weather is the issue because of the fact that i live in southwest florida. thank you for the response and referencing the home made code scanner. i made mine last night. you're correct about them being part #s at RadioShack but not everything on the list was found & i used a few different pieces. no resistor (12v LED), different SPST switch, no fuse, but it'll work all the same. I'm going to check the crank position sensor and replace that if it's faulty. ill be back later with results
