So I'm getting fuel to my injectors, and I have power to my coils. My engine flooded with gas since it was cranking but not starting. I'm going to replace the, now wet, spark plugs but I want to eliminate all other problems so I dont flood it again with new plugs. How do I check to see if my PTU is working correctly without replacing it? I have checked every other system in my car regarding it starting. Any ideas?
