Depends on what your losing. Is the fuel stopping or the ignition stopping? Trying cranking the engine til it starts and spray starting fluid into the throttle body to see if it stays running. if it does while your spraying, the you know fuel is being lost. Re-check your work. If it is an Airtex fuel pump, that may be your problem right there. Check if the security light is flashing when you start the car. If it is try your valet key, it should work. You will have to reset your black keys. It's easy ask a dealership MAXX5550 THE WIRING THAT LEADS TO THE FUEL PUMP GOES INTO THE UNIBODY. CHECK THERE FOR CHAFFING.
Electric start,
motor can cut out , stall or not start at all.
Single phase induction motor ( usually capacitor- start type)
Do you have fuel pressure ? It must have 9 to 13 LBS. No higher or lower are you will have starting and running problems.
Were you having problems before you changed the filter? If yes you probably have a bad fuel pump; if no there is likely some kind of fuel blockage in the supply lines or filter. Again, it still could be the fuel pump.
is the fuel filter istalled correctly in from fuel line out to engine. PS won't be the first person to install it backwards
is your a4 diesel ?
could be oxygen sensor. there actually are two on the car. could be alot of different things. vacuum leak possibly, fuel pump.
Because when your car runs out of gas there is no more gas in the fuel lines to run the motor so when you refuel it then start it there is nothing there to keep it running. The gas have to be pumped out of the tank and into the motor.
No.
I think the resistance value of starting winding is less than the running winding of the single phase motor
The run winding of a single phase capacitor start motor has a lower resistance than the start winding.
