What does it mean when your car stalls then the Check Gauges light comes on the oil pressure indicator slips to nothing and the oil is full?

Sounds like you might have a bad motor. Have a independent repair shop take a look to see if it is still salvagable.

AnswerYour "Check Gauges" light SHOULD come on, and your oil pressure indicator SHOULD go to zero if your engine isn't running.

Your oil gauge indicates the pressure of the oil, which is being generated by the oil pump, which runs only when the engine is running. The "Check Gauges" light is simply indicating that your gauges are indicating something potentially harmful (low oil pressure). Since the engine is no longer running, this is normal.

The stalling on the other hand is another issue - it could be many different things and would be easier to diagnose with more details: does it stall on startup? Just once or continually? When it's cold? When it's hot? When it's raining? When you go around a left turn? When you run out of gas?

More details could help.

AnswerMy dad has a '91 Plymouth GrandVoyager, V6, 3.3liter with currently 200k miles on it. His car was running fine around 3months ago, it was still a reliable daily driver. However, when he changed his type of fuel to E-10 (A Biogas with 89 octane, 10% ethanol) his car kept on stalling, especially during hot summer days and after traveling 60+ miles. Some part of the issue was resolved when switching back to normal higher quality fuel, because the alcohol in the gas vaporized faster and created sometimes a tank lockup and not allowing any fuel to get pumped to the engine. When it stalls, the CHECK GAUGES light goes on and will stay on. When trying to start it again, it just cranks and tries hard to start up. After 30mins, it will start up again, but light stays on for a while.The fuel pump was replaced withing 18 month and still gives sufficient flow and pressure. so i don't know on what do do next. the oil pressure has been a little bit low for the last 2 years, but doesnt seem too cause trouble. also, when filling the tank up with new gas(which is colder then the one in the car), the problem seems to disappear till somethings malfuntions again...

so, if anyone knows what the CHECK GAUGES light exactly means or what causes it to light up, or any other suggestions, they are greately appreciated.

thanks
