1992 2.0 liter 16v GTI cold start issue,can't use the gas pedal until car is @124 degree engine temp or it will die,floods,has new fuel pressure regulator,knock sensors,distrubutor,idle stablizer,

When a temp sensor goes bad, it usually fails to a setting that makes the ECM think the coolant temperature is about -40 degrees F. This makes the ECM send MASSIVE amounts of fuel to the injector(s) in what it thinks is an extremely cold start. This causes the engine to flood and makes for a hard start. You may be able to get the car started if you do a "Clear Flood" procedure, which is to hold the gas pedal to the floor while cranking until the car starts. Even then, though, the car will run so rich that you may have to keep revving the engine to keep it from stalling out at idle. On the road, it may seem better, but your fuel mileage will be awful.

check egr valve for carbon and proper function --also check cat converter possible clogging

This can actually be several things but most common is the coolant temp sensor, it tells the computer how much fuel to give the engine depending on temp, if the sensor goes bad then it may be giving engine too much fuel when it's warm, which may be why it starts fine cold cause it needs more fuel to start cold, try holding the gas pedal to the floor when u start it warm, if it does start and run rough for a few seconds it's cause it was flooded due to excessive fuel.. Get scanned for any trouble codes..

On electronic fuel injection pumping an pumping an pumping the gas pedal does nothing without the engine running ! Pushing the gas pedal to the floor will cause the PCM - engine computer to go into clear flood mode .

You have some very interesting ideas here , but not really how it works or is !

The vehicle will go into closed loop fuel control when the engine coolant temp reaches a definded temp an the O2 sensor get hot.

She would run for a couple minutes and die which is open loop when running, closed loop is when the sensors kick and it would die. Pulled spark plugs, they were black meaning no spark. Can only be 2

Black spark plugs indecate a rich condition , over fueled , wet spark plugs indecate no spark .

Okay. If the problem occurs when the engine is cold, check for leaking fuel injectors by doing a fuel system pressure bleed down test. A leaking injector will drip a lot of extra fuel into cylinder and cause it to rich misfire until enough air can mix in to lean it out. (Which you are supplying with wide open throttle). If the problem occurs mainly with the engine warm, check the engine coolant temp sensor and the intake air temp sensor. If either of these sensors is stuck at full cold, the computer will send too much fuel to the injectors for a warm start and again flood the engine.

thats because the car is not at operating temperature.you will get a slight drop in power and drivability until its warm.do not try to use any more than 1/3rd gas pedal until its warm anyway.your car has an automatic cold start device (choke)that operates when the car is cold.

Try flooring the gas pedal when you go to start it (but quickly remove your foot on the pedal when the car starts).

That is just to clear the flooding (it's called clear flood mode when the accelerator is floored before the engine is on).

You need to replace your Engine Coolant Temp sensor. It is dumping too much fuel in your engine and not allowing it to start. The stock one is plastic and cracks. It then sends a signal to the PCM that the engine is -40F (that's negative 40 degrees F as in below zero). The PCM then tries to warm up the car by dumping fuel in it but since it isn't that cold it causes a problem.

Get a new brass one from AutoZone or the like and replace it. It's a 10 minute job and takes a 13MM deep well socket.

you need to check to things out,
first is fuel pressure at thr fuel rail reed valve,you need at least 50psi for the injectors.
second have someone check the engine temp switch,to see what temp it is telling the computer your engine is.
if it tells the computer your engine temp is 65 degrees,the computer will not push as much fuel to thru injectors,when your engine is cold the computer needs to know how rich to make it for cold starts

i was once pulling a trailer with a ranger when it suddenly lost power and the engine died. turns out the problem was with the fuel shut off inertia switch. the switch is supposed to activate in case of accident. on my model the inertia switch is located in the passenger side under the glove box. dont know where yours is located. once you find it, just push the button and see if it resets. good luck.

hi there, im thinking egr valve because of loss of power and erratic idle or the idle air control valve because it also too has the same effect
