bought a tow-yard auction truck ('07 SIlverado) the other day so been getting it ready to roll.
-battery dead: replaced (and the stereo starts playing mexican music as soon as it got power 🙄)
-checked oil: black gold, sludge on the dipstick, and a quart low! (but no milkshake)
-radiator: over flow empty , poured a gallon in (sucked it all down)
-20" front tires: off the rim so got used pull-offs at Discount Tire (got 4 excellent tires for $20/ea with 9/32 left, $175 out the door with mount/balance! those tires are $190 each!)
started it up....no CEL or nothing. OBD code reader has 4 codes (3 ABS, 1 BCM)
