I had this problem with my old Audi 80 and basically it was a knackered fuel pump. If your car is a few years old avoid the main Audi dealers and take it to an independant Audi/Volkswagon specialist and you will save a small fortune.

SOURCE: BRAKE LIGHTS STAY ON ENGINE RUNNING BUT CAR WONT DRIVE

there is a button on your brake pedal lever that while braking gets depressed, and turns on your brake lights. Now this component is a plastic piece that can get knocked loose rather simply. You either need to re-secure this component, or replace it

(you can get this part at any junk yard for nothing more than some pocket change)

You could also short-circuit (reset the computer of the car).. Just leave the red wire connected on the battery, disconnect the other cable (black one) that goes on the battery (-) and connect the black cable with the read cable.. That should reset the car computer and let you start the engine.. You have a sensor or something broken in your car.. My advice is have your car checked by specialists (best solution). Good Luck.

SOURCE: 2005 Audi A4 1.8 Fuel Pump problem?

I had an Audi A4, 10 years older than yours mind you, but it would start then stop, sometimes 10 times but would eventually go. I ran a little WD40 in the key barrel and put the key in and out a couple of dozen times. Wiping it with a cloth each time, lots of dirt came off. My theory and it's only mine, is that the wear on the key left dirty metal deposits inside which stopped the chip in the key being recognised. I believe they had a security chip inside the key.
Anyway after 6 months of this nuisance it never happened again after that. Fixed my problem and a lot of frustration. Maybe help you too.

2010 nissan versa got in a collision. Wont crank over. Would the fuel inertia switch cause this?


Fuel inertia switch stops the fuel pump running in the case of a collision causing a broken fuel pipe which otherwise could spray a litre of petrol every few seconds and rather spoil someone's day.

Certainly a tripped inertia switch would prevent the engine from starting but I doubt it would stop the engine cranking, though I don't have up to date information on the model and there could be different safety regulations where you are.
The inertia switches are accessible and resettable so why not just reset it and try again. Your vehicle handbook will have the details.

An immobiliser stops the the engine cranking on some vehicles as well as stopping the spark and injection and often the fuel pump.
Bridging the battery positive wire to the solenoid to make the starter crank the engine won't be switching the rest of the stuff back on.

Fuel pump not running


You will find a reset button on the Inertia switch. The Inertia switch may be in the trunk or behind the kick panels of the front seat floorboards.

The Inertia switch is a safety device which cuts off the power to the fuel pump after a bump or collision. If closing a door or trunklid hits the right frequency, the switch will cut the power. Just reset it.

Turns over, won't start


Make sure you hear the fuel pump run for a coupla' seconds when you turn key to on.You might need to push the fuel pump inertia reset button(for collision purposes,it shuts off pump).
Next check for fuel pressure at the fuel rail feeding the injectors.It's like a tire valve,but it has pressurized fuel so be careful, and check only a cool engine with the switch in `run' position,engine not running.

Car was running good, took a ride and came home, turned the ignition off and car won't will not start again. What could the problem be? Caulley2@aol.com


check your inertia switch and press the button on it for a couple of seconds. This part cuts out the fuel pump in collisions and sometimes just the right bump closing the trunk or door will trip it. This part is usually in the trunk on most cars.
