Hi,

We need to run a compression check to make sure that is ok. We need three things (compression, spark, and fuel) to start an engine.

How did you check fuel and spark?

Also, what is the history of this? Has it been sitting or did it happen after you did something to engine? Replace any parts?

Lastly, we need make sure the spark plugs are not fouled. Long cranking when it is dumping fuel will cause the plugs to have a weak or no spark which will cause a no start.
