2000 Tahoe, 5.7 Z71 Blown Head Gasket ( 5/20) so it will start and has lots of power. Water pump when out and temp gauge sensor must be not reading correctly because it never showed hot. Swap motors or just change out head gasket, water pump, throw in some new oil and you're rolling. I'm not going to fix it this time. Just put in a new Fuel pump, plugs, wires, cap, rotor. 4x4 works great.
