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?

93 seville sts runs great and then after driving wont star fot 30 min to an hr. any easy solutions?


If/when you do get it started, do you have to hold the petal to the floor or give it a lot of gas to 'clear' it up again? Does it smoke when you first start it up? If so, you might have a leaking injector (s), the o-rings allow pressure to push gas into cylinders when you shut down, flooding the cylinder-will cause hard starting. If this is not the case, consider a heat-sink kind of situation with the crank sensor-it gets hot with normal driving, and gets even hotter with heat-soak when shut down and changes electrical properties (specifically resistance) until it cools down again. change the crank sensor.

Pull your vacuum line off your fuel pressure regulator and see if it smells like gas in line or if gas runs out of the line.

93' 4.3 chev runs rough at times


Have someone turn the key on while you watch the injectors. If any gas leaks out of the injectors, without cranking on it) replace the o'rings around the injectors.
