Starter went out on our 2002 Suburban 1500 4x4 5.3L. I replaced the starter and after getting the new one installed, vehicle wouldn't crank. Sounded like the starter was engaging but the engine wouldn't start. (Old starter would just click and do nothing when trying to start, so it's an improvement). Went back under the vehicle and checked out the starter. There were 3 loose wires hanging that weren't hanging before. Best guess is they got pulled loose when getting the starter in or out. They are thin gauge. A yellow, blue and green wire. I've looked online trying to find a wiring diagram but haven't found anything that lists wires of these colors. There are running in the same protective cable as the wire that goes to the small pole on the starter solenoid and the wire that goes to what I am assuming is the oil level sensor. Any help is greatly appreciated.
