Not firing on all cyls

[ikmrbju]

My 2.5 l 4 cyl Voyager is not firing on cylinders 1 and 2.
I replaced the wires, dist. cap, and the plugs. No difference.
This car has a single ignition coil, and a single fuel injector. This eliminates computer or sensor problem. When the engine runs (roughly) there is water droplets coming out of the exhaust. Not the coolant, plain water. Collant level remains the same. I'm thinking head gasket failure between cyl 1 & 2, causing loss of compresion.
