95 Sentra wont start!

My 95 Sentra won't start! Monday I went to turn on the car and it would not start. Here's what I know: Engine turns over, battery fully charged, there is spark, fuel pump works, fuel filter works, spark to fuel injectors etc. Spark plugs come out wet (with fuel), cylinders are cleaned and dried and when ignition is turned the cylinders become flooded with too much fuel and floods the engine, hence it wont start.
I've never done any modifications, the car has never given me any problems, just wouldn’t start (out of the blue).
Any suggestions would be greatly appreciated! Thanks

Hmmm, Injector fouling USUALLY happens when peple change their fuel system and don't know what they are doing. but if your car is completely stock it would be best to check the obvious things first. make sure the Coolent Temperature sensor and the o2 are still connected and working correctly If your CTS was unplugged it would always read -40 degrees and it would flood the engine trying to start it. You may want to make sure your fuel return is working correctly and not letting it build up to much pressure.

Hey mreff thanks for the advice. I've done some searching online and there have been instances where the water-temperature sensor may cause this type problem even found where the catalytic converter may do the same. I'll have to check these out. Thanks again.

No problem. Water temp and CTS are the same thing.
The only way I could see a cat causing that particular problem is if the cat was so restricted that it was making an incredible amount to backpressure and stopping scavenging all togather
I doubt it's your cat. but if the problem isn't fixed soon you will more than likely burn up your cat

I've had a similar problem today I tried disconnecting the ECT sensor, the engine started (it was rough but did start), I reconnected the sensor and the engine smoothed out.
However you will trigger an error code if you didn't already have one.
In my case I was able to clear the code, and read that the sensor did appear to be functioning, it was reading 178 degrees, after it had been running a couple minutes.
this is the 3rd or 4th time since owning the car this happened, the car was 1 month off the lot I did get the car new, Nissan said it was flooded and that all they did was start it (if that's all they did how come it wouldn't start for me, maybe I turned the key incorrectly) 2nd and third time Nissan said the same thing though different dealers. I was just more curious this time, and had more time to fiddle and investigate.
Hope this helps someone in the future I'm figuring it's late in this thread.
