Re: 2011 Denali 6.2L No Oil Pressure
OK, here's an update. The dealer actually changed the sensor, dropped the pan and changed the O-Ring. Test drove and pressure is still going to zero. To change the oil pump and for all the work done we are at $1290 + tax. GM is willing to pay $650 as assistance. The dealer mechanic is confident there is no damage to the engine, I'm very uncomfortable with that analysis. So I'm faced with changing the oil pump and rolling the dice that the engine is unharmed, or just replacing the engine at roughly $8K. Wow this sucks!!
