Gave a 1979 Buick turbo regal with the 3.8 turbo, engine cranks over but doesn't start, there is gas coming out the carb, power coming into the distributor unsure if it's firing at the plug yet.
Remember the 3 famous things that make an engine run: fuel, spark, compression! If you got fuel going into the cylinders and spark on all cylinders, do a compression check on all cylinders. If any ONE cylinder has low compression, it can cause a no start condition.
