Starting issues. I replaced the heater core over the winter. When everything was put back together, this is the sound when I turn the key to Start. Battery is good. Starter is good. I ran a wire directly from the battery to the starter control wire connection on the starter, and - with the key in the Run position - it started, which means the starter, relay, etc. are good, correct? I can't tell where the noise is coming from or what it is. I'm guessing I messed something up taking the heater box in and out, but I can't find much documentation about what's in the mess underneath the dash. Ideas? 1988 4.2L manual
