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.
motor can cut out , stall or not start at all.
Single phase induction motor ( usually capacitor- start type)
is the fuel filter istalled correctly in from fuel line out to engine. PS won't be the first person to install it backwards
It cranks the engine over in order for it to start running.
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.
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 your a4 diesel ?
I think the resistance value of starting winding is less than the running winding of the single phase motor
could be oxygen sensor. there actually are two on the car. could be alot of different things. vacuum leak possibly, fuel pump.
Most refrigerators use a single-phase induction motor which needs a capacitor to make it start running in the right direction.
A start capacitor is wired in series with the motor's start winding via a centrifugal start switch. The switch disconnects the capacitor and start winding once the motor has reached a pre-determined minimum speed. The motor then continues to run on its main field winding. A different design uses a "start-and-run" capacitor which remains in circuit whilst the motor is running.
it may be hard to start, stall, or stop running altogether.
No, a three phase motor will not start if one leg of the motor feeder is open. The motor will stay running once the motor looses a leg butnot for long if the proper motor protection is provided. The motor protection will sense theline failure and disconnect the motor from the voltage source.
Replace the fuel filter.
Do you have fuel pressure ? It must have 9 to 13 LBS. No higher or lower are you will have starting and running problems.
Check the ignition coils and the crankshaft position sensor. One of these could be failing as they heat up.
Check your Air Filter connection. Many times if you go to the shop to get your oil changed they will also check and see if you may be in need of a air filter. Sometimes they forget to tighten the hose connected to the Air Filter, which could cause the car not to run. It might start, but will not stay running!
starting winding are thicker than running winding
If a car will turn but not fire/stay running after it runs out of gas completly. This could have caused a few things to break such as the fuel pump/sending unit. Also might just be a clogged fuel filter. When you run out of gas you suck everything such as rust and dirt through the lines and filter which can clog it. First thing i would try is to turn the key to on but not start it and stick your head by the gas tank and try to see if you can hear the pump run. (it will sound like a little electric motor running) if you hear that then try to discnnect the fuel line at the motor and turn the key to start and see if you get fuel. If you get fuel then it is a spark problem after that.
Start by having the fuel filter changed.
Start by checking your fuel filter.
Start with replacing the fuel filter.
i would defiantly start by changing the fuel filter
