Does it have injector pulse? I have seen some of those Pontiacs with the 3.8 rot out the upper intake manifold around the EGR and fill the intake with coolant causing no-start conditions and random misfires,is coolant mysteriously diappearing?

The leak I am refering to doesnt put coolant into the oil, it goes into thec ylinders and wets the plugs causing misfires and no-starts.Have you checkced for fuel pressure? GM pumps are great for only lasting about 100k
