It sounds like it's been flooded with fuel. Take the plugs out and dry them off then put them back in. When you start the car, hold the accelerator/gas pedal down (don't pump it). This will help to remove any excess fuel from the cylinders. When started, let go of the accelerator (obviously :) )

I have a Nissan hardbody 2.4i petrol the plugs are getting wet and it starts to misfire what could be the cause

It is a chicken and egg question - which came first, the wet plugs or the misfire?

Are the plugs wet with fuel or is it oil?
Are all the plugs equally wet?

If the ignition system is in good order and the correct spark plugs, correctly gapped and in good condition are fitted, it would be expected if the engine was receiving (moderately) too much fuel, it would keep running until the plugs were completely sooted, black and shorting out and unable to spark properly but at that moment the plugs would still be quite dry.
Persisting after this will of course cause wet plugs if the engine is still relatively cool but the sooty evidence of what has happened will still be there.

If the plugs are relatively clean but wet it is unlikely to be fuel as such large quantities that is would take to wet the plugs without any sooting it would be doubtful if the engine ran at all.

I hope I have provided you with food for thought. If you need to post again please provide accurate and detailed descriptions of the symptoms and what you have already checked.

Have a 2004 nissan altima plugs getting wet with gas take them out and dry car starts but same problem after 5 6 hrs won't start again what's the problem

Your engine is flooding with fuel which is why you have wet plugs and why you are having problems starting the car. A flooded engine will not start.

It sounds like a recurring flooding problem rather than a one off and the injectors may be leaking. One way or another too much fuel is being delivered by the injectors.

Get the car into Nissan Service and have them check it over and identify the cause.
Here is some information on the flooding problem prepared by a professional master mechanic.

I have no plug wire spark 1997 dodge average 2.5 v6 24 value.have already replaced crankshaft positioning sensor on it and still no spark to the wires

Sounds like a bad distributor. Had you pulled a spark plug out you may have found them wet with gas after cranking. If they are wet the crank sensor is working since both injector pulse and coil pulse rely on crank signal.

The distributors are known week points in the ignition system and used to be common when theses cars where still on the road. A reman will run you $250 U.S.

Tried all that spark plug and block sensor its not that. what else could it be

Not the same person here, but have you made sure the fuel injectors are working? You can check the injector circuit with a tester called a "noid light", available at any parts store at a minimal cost. If the injectors are spraying gas into the cylinders, and the engine is cranked over quite a bit, the spark plugs should be wet with gas if you pulled a couple out and looked at them, or smelled them. If they are dry, gas may not be getting into the cylinders. Air, fuel, compression, and spark- one of them is lost or missing if the engine won't start.

Car turns over but seems no fuel getting through from pump to filter

You need to find out if the fuel is reaching the cylinders and if the spark plugs are firing. Pull the spark plug wire off one plug. Insert a phillips head screwdriver into the end of the spark plug wire and ground it against a metal engine part. Try to start the car while observing the screwdriver. There should be a spark jumping from the screwdriver to the engine. If there is no spark, you will need to do further troubleshooting to find out why. Now, remove the spark plug that the wire cam from and check it for wet fuel. If the engine is getting fuel the plug will be wet with gasoline. If the plug is dry, Then either your fuel pump is not working or the fuel filter is plugged up. Let me know what you find and I will help you with further troubleshooting.

Try to start truck but battery dies.

check your ground wires. its quite common that they rust off and then that causes a no start. check along the frame by the battery, and starter.

2001 santa fe will not start. was running fine. Fuel pump seems to be working all fuses good. engine turns over. ????

since the engine turns over, it can't be the starter.
Since the fuel pump seems to be working, it is not likely the fuel, but still could be. If you are getting fuel, the plugs should be wet by now. If they are not, then try spraying some starting fluid.
It it sputters at all, then it is a fuel problem still.
Which could be lots of things.
If it does not even sputter or the plugs are wet, then it is spark.
Verify by attaching one of the spark plug wires to a spare plug that is grounded. See it spark. If not, check for ignition power to the coil. If power, then suspect either distributer pick up or coil/control unit, all of which can be checked for free at a place like Autozone, if you bring in the parts.

LeSabre won't start...please suggest...

To check fuel supply, spray carb cleaner into air inlet while cranking. If there is no fuel, engine will start for a second on what you sprayed. if nothing, likely either there is enough fuel and plugs are already wet, or there is another problem. (perhaps contaminated fuel?)
