The rich fuel problem is not constant, implying the problem seems to come and go. Remove and inspect the spark plugs to determine which fuel injector is giving too much fuel. Rich fuel will result in excess carbon build up on the spark plugs. Pour fuel injector cleaner in the fuel tank and see if this corrects the problem. Samtoler claims its's the fuel pressure regulator, which I disagree. If this were true, the problem should had been constant, not random. With faulty injectors due to carbon build up, the carbon will come off at random times, then come back on, resulting in poor atomizing of fuel at random times.

2000 plymouth voyager has white smoke from exhaust that smells strongly of gas. It runs great, but does not get very good gas milrage compared to the one I had before. What is the problem?


A bad coolant temp sensor causes the ECM to read-36 degrees. So the ECM will dump fuel because it thinks it's really cold out. A stuck open T stat will cause this, not as bad as the sensor though. Injectors that stuck open will also dump fuel all the time.

1997 plymouth breeze is running rough and the exhaust smells like gas . replaced plugs made no difference


IT IS POSSIBLE THAT IF YOU GET A SMELL OF GAS THAT IS AN INDICATION OF THE ENGINE RUNNING RICH. THIS IS USUALLY CAUSED BY A BAD O2 SENSOR. YOU WILL NEED TO SCAN THE VEHICLE IF A CHECK ENGINE LIGHT IS ON.

My 1995 Plymouth Voyager loses power, surges and backfires.


My first instinct tells me timing chain or belt, but it could be a vacuum line loose, cracked or disconnected. Using a stethoscope, or a length of gasline hose held to your ear, and with the engine running, listen for a hissing sound. Be sure and wiggle all the hoses you can. You might make one hiss. If you don't find anything, get a timing light, and check your timing marks. They should stay in basically one spot. If it's jumping around a lot, you need a new timing chain or belt. Good luck.

i can tell you its not the fuel pump.if you smell fuel then the pump is working right,you may have a weak crankshaft sensor though which would keep it from starting and running. but its definately not the fuel pump maybe you have water in your gas
