Leaking fuel injectors or excessive fuel pressure, that is really about it.

Fluids out when you try to start


double posted, and fluids? you mean FLOODS.
see previous post,
there are other ways to flood any motor.
one other is (iSC /IAC devices are stuck closed) gummed up.
this cause no starting air, no air means flooding.
I cant see your car, and see if starting with 10% throttle solves the flood, but you can.
also WOT cranking, cuts all fueling and can not flood and will start any flooded engine.
but if this still floods,now, that is bad injectors. leaking.
WOT cuts injection pulses dead, and no fuel flows, cranking.
knowing these facts on EFI makes finding causes easy.

Floods when cold


Define flooding.

  1. Black smoke out of the tail pipe?

If the fuel return line is plugged,it will flood.If the fuel pressure regulator has lost its vacuum signal ,it will flood.

If there is a large vacuum leak,the O2 will see a lean condition and cause the rich condition.gas mileage will suck,big time.

This "flooding" happens when the engine is cold? ONLY?
Be sure the air filter is not clogged and the PCV is not plugged up solid.
Also,there are a few tubes from the valve cover that vents oil vapors into the air filter housing.

During this flood mode,hold the pedal to the floor and shut the engine OFF-it should NOT keep running.(Leaky injectors)...

Do this when engine is hot and cold.

What causes the 2002 nissan se r to backfire


Sounds like an ignition or timing problem.
Is the check engine light on ?
This engine uses a direct ignition system which means each cylinder has a coil on top of the spark plug. It could be as simple as worn out spark plugs.
If you had said the engine backfired and was hard to start, but no flooding, I would also look at low fuel pressure. But too much fuel causes flooding.
A faulty throttle position sensor could cause all of your symptoms, but it should set a trouble code and turn on the check engine light.

98 RAM 1500 WONT START


Replace the coolant sensor NOW!? Its causing a flooding condition as evidenced by wet plugs that short out when flooded. Blip the starter and see if raw fuel is blown out as another indication of a flooded condition. In cases of flooded engines, holding the gas pedal to the floor shuts off the injectors during starting to clear out the cylinders.

The brass replacement sensor will cure flooding and many other engine/transmission issues.

My 1992 hyundai sports coupe seems to be


HI. Two issues here. The first will be with your fuel pressure regulator. this device can fail, mechanically, thus, causing an inappropriate amount of fuel to be introduced into the system. this will cause flooding, due to a ruptured diaphragm. I recommend to have this device inspected for damage.

The second issue will deal with a failed injector(s). Injectors can fail In this way, as well. This device can become filled will debris, thus, causing the mechanism to not close completely. This will cause flooding, in this case. replace any injector that is damaged in this way(stuck open).
