All around bad day for my two Chevys. First my Suburban got rear-ended.... then my S10 blew something on the intake manifold. Driving down the highway, there was a loud pop, then it lost all power. Got it off the road and shut it down. Found coolant all of the engine bay. Now it won't start. Did a pressure test on the cooling system and coolant was spewing from between the intake manifold and the valve cover. I guess it's the manifold gasket. What I'm really asking here is why won't it start now? Would a bad manifold gasket cause a no start problem? It cranks just fine.
