I changed the LIM in my 06 Grand Prix and my car wouldn't start, turns out from trying too much and having one leaky injector I flooded the engine. I disconnected all the spark plug wires and removed the front 3 plugs and attempted to turn the car over until all the fluid was removed. Put everything back together (replaced bad injector) and it started right up. Hope that helps
Changed the upper and lower intake gasket and the car turns over but won’t start
