Check for loose connections on your ignition system, mainly around the coil.

SOURCE: Fuel Injectors leaking

Where the injector's mount to the fuel rail and into the eng. there are o-ring's.Check the o-ring's for damage.If the o-ring that seal's the inj. to the fuel rail is damaged it will leak alot from the pressure of the pump and make the car act like it's running on 3 cylinders because there is no fuel going to the cylinder to ignite.If there is a bad seal in the area where the inj. goes into the cyl.head it will leak a little and should be fixed as well.When installing new o-ring's lube them up litely for a easier install.Be sure to clean the gas up so you dont ignite any spilled gas.Hope this help's.

Yes, could be any number of things. It could be the TPS (throttle posistion sensor) as this is the culprit of most idle issues with fuel injected vehicles.

When hot will randomly not start unless gas pedal is pressed all the way down. on a 2001 honda crv. replaced fule pump,fuel relay,fuel filter, dist. cap, rotor, coil,plugs, wires, and ignition control


If you hold the pedal to the floor it puts the fuel system into Clear Flood Mode. This prevents the injectors from firing and lets the already present fuel burn out. Now if this has to be done on every short trip you probably have a leaking injector.

Does the vehicle seem to crank slowly or stop and then crank when this happens?

1990 toyota celica fuel problem. It appears to be flooding. When cranking, if it has been sitting for a while, it fires for just a second, and then dies. When the fuel pump is unplugged, and engine...


start with trying to start the car with your foot hard on gas pedal, all the way to the floor this will stop fuel flow on start up its called clear flood mode. as the engine starts to fire and run ease off the pedal until it idles, it may take some time to run smoothly. if it doesnt run or stalls after a short time and then will not run i would try a ECU engine control unit as it supplies the earth circuit to the injectors, may be thats whats holding them open or they are dribbling badly and require overhauling

Experienced recent cold weather. Car will not


It's flooded like you say.
If it's really flooded, you'll have to remove plugs and dry them off.
Install them.
Now when you crank engine, hold gas pedal to floor.
That will stop gas from spraying into engine.
You need to get the gas out of the engine for it to start.
Crank for 20-30 seconds with pedal to floor. Do this 3 times waiting 2-3 minutes inbetween cranks.
The starter needs to cool down.
Then after that start normally and see if it will start.
Remember if it will not start after 2 attempts, then the possiblity of it flooding is there and you'll have to clear out the gas by holding the pedal to the floor again.

The 1996 Chev Cavalier runs great. Then I stop,


It sounds like the fuel pressure regulator has gone bad and needs to be replaced. Start with that if your engine is flooding over with gas as you ****. If there is an Auto Zone around you area, have them scan the car for any DTC codes that may be related to your car not starting like a bad MAP sensor which would also cause a no start when the engine is hot. Auto Zone also carries the parts you will need to replace and can give you the step by step instructions to replacing the parts with common tools. If your good with tool both job should take about 30 min to replace. Good luck and keep me posted
