I have had the car for about two or three months, ever since I have gotten the car the spark plugs and the engine seem to always get flooded out with fuel, causing a crank no start. I have change little things over time such the crank and cam shaft sensors, fuel pump, ignition coils, fuel injectors, and the fuel line. I have taken the car to a shop and my mechanic ran a diagnostic and couldn't pinpoint why the spark plugs constantly get flooded out. Any new advice would be appreciated.

Good morning,

What makes you believe it is a fuel delivery issue?

Has anyone verified spark when it would not start?

Are there any codes stored in the system?

I don't have any codes at all surprisingly, usually i’d have a lingering p0420 code. I can take all the spark plugs out and they’re soaked in fuel and when I look down the chambers I see puddles of fuel in each one. I tested out the spark plugs when I dried them off and was able to confirm they are definitely getting spark.

Okay, if you have spark and fuel, check the compression to see if the valve timing is correct.
