My 1998 Volkswagen Beetle keeps dying.

Check fault codes.

check fuel pump.if there is a small , even hairline crack in the diaphram it will do as yours does. good luck.

indicates a recorded fault
have the fault codes read and fix the faults

Could be the fast idle sensor check to see that the vacume line is hooked up properly.

maybe coil pac!!!

think you may have caused the car to go into safe mode.you need someone to plug in a diagnostic computer to erase fault codes in the cars brain. hopefully that will sort it out!

When was the last time you had your fuel filter replaced ?? Sounds like the engine may be starved for gas because of a clogged fuel filter. If you have no record of having been replaced, this may be the least expensive place to begin, but be careful the quick disconnects on the fuel filter can be difficult to push in. Also, the fuel lines will be pressurized when they are disconnected, and could spray gas into your face if your not careful. If you damage the disconnects on the fuel lines you will need to have the lines replaced, so be gentle.

possible engine coolant temp sender

this can be caused by a bad fuel filter or dirty injectors. try a bottle of fuel injector or fuel system cleaner in a tank of gas. i suggest lucas products which can be found at any parts store.

Hi..
The fuel Pressure for your Beetle. with 2.0 L.
Is 36 Psi. engine idling.
43 to 55 engine off.

If you Spray fuel in the throttly. and keep running.
But if Only start and die.
Check the factory alarm.
Check if you have the right KEY.
The KEY on this car use a CHP inside. to prevent the car to be start with out the right key.
If the key is BLACK and look like use chip.
Check the Red LIGHT on the driver door or cluster , if the light is Flashing the SYSTEM is activated try to desactivate with the KEY on the DRIVER door lock Cylinder. if the light goes off
Try to start the car.
If your car is not equipated with CHIP. see if the light is ON or OFF.

Ok. I hope this help to diagnostic your car.....
