Oil was leaking into my sparkplugs and it was my valve seals I replaced the seals and no more oil and the car was fine. Now it is having the same issue. I have change the plugs today and it started up fine. The old plugs was wet with gas. After the car sat for 4 hour I had to go out it took a while for it to start. I think the engine was flooded with gas. Could it be my injectors are staying open and gas is leaking in? If so how can I fix the issue.

 

Cold start flooding can be caused by low fuel pressure; try turning on the key and wait for the check engine light to go off then crank the engine.
You didn't mention what kind of sparkplugs you installed but I will say the tiny platinium tips have a bad reputation of flooding on cold starts.
If you think you have bad injectors you'll have to do a fuel pressure leak down test.

 

Although possible, I wouldn't think that ALL your injectors would fail at the same time. It's what's referred to as a statistical improbability. One possibly, Two maybe but three or four - you'll have to convince me. As mentioned before chk the fuel pressure. You also might check before you start the car for the first time for residual fuel pressure in the fuel rail (there should be).
