Whats the engine code for a 1985 Chevy 305?
VIN code "H"
When you say "reset" button, I assume you have a check engine light on. There is no reset button. You either need to have the PCM scanned with a scan tool to see what fault code is indicated or you can try to clear the code(shuts light off) by disconnecting the battery for 30 minutes.May come back on if failure sets whats called a "hard code".Need to address if hard code.
