1988 Chevy Corsica 88 Chevy Corsica -No Start

1988 Chevy Corsica 2.8 V6
Car has spark, fuel pressure didnt have injector pulse from noid light. Replaced ECM, injectors have pulse, fuel pressure good, has GREAT spark, still no start. Pulled out spark plugs which were wet and replaced, still no start.I am suspecting possible crankshaft sensor, but was told if CKS sensor was bad, I would not get injector pulse or spark. Possible timing chain failure?Compression test?
Any help would be great.
