1998 Audi A4 starter spray

Yes. But it's only a diagnostic 'tool.' If it cranks and runs for a bit with the starter fluid, the problem is no gas getting to the engine and you go from there.

if it starts with starter fluid then its a fuel problem. check the fuel pressure and volume with a gage. these require at least 56lbs pressure to open the injectors and if the pressure is at 52lbs the they will not open. these use the pressure to open the poppet injectors and have a problem with the spider lines cracking and leaking fuel inside the intake. this is probably why it won`t start on its own.

As it cranks, is there white or black exhaust smoke ?? If yes, the fuel injectors have solid build up on the tips. Normally, a quart bottle of injector cleaner treats 20 gallons. Pour 5 to 7 quarts of fuel injector cleaner. With cold engine (been parked for at least an hour or overnight), while cranking engine, have 2nd person spray starting fluid into air filter. DO NOT PRESS ON GAS PEDAL !!! Let the starting fluid do its job of starting the car. Starting fluid is highly combustible, so its important you don't give any gas while its cranking and 2nd person is spraying into air filter. When engine starts, stop spraying starting fluid and give a little gas. If engine begins to die, immediately spray a little starting fluid again. When engine begins to run, let it run a few minutes to let fuel injector cleaner to do its job (loosen solid carbon build up on tips of fuel injectors).

into the air intake where the air filter goes

starting fluid is a thing of the past. dont use it. this car doesnt have a carb, its a throttle body/ electronic fuel injection system. you most likely have a fuel pump or fuel pressure regulator issue. test the fuel pressure, should be anywheres from 35-50 psi

Best way to fix it when you run out of gas is this. Because you ran out of gas, means your fuel filter is out. When you run out of gas, you end of getting like a air blockage in the line. Now, professional way is to take fuel filter off and fill with gas and put back on, BUT i will tell you a back yard mechanic secret way. Is get a can of starting fluid ( you can get at any auto parts store) and while someone is in side the Pickup, have them ready to turn the key. You are outside with the hood up, and you will be spraying a little bit of the starting fluid in the air intake of directly in carb area ( if carborated) but just spray into air intake. Have them crank the engine, at same time you will spray starter fluid in air intake, just a couple of quick sprays. You will notice it will start and maybe die again. That is normal, you might have to do this a couple times to get things flowing. HOWEVER, what normally happens when you run out of gas, the fuel filter picks up all that junk that has been gathered in the bottom of fuel tank and it has clogged your filter. FOR SURE, if you replace your fuel filter, it will solve this problem. Thank You, and I hoped this helped you.

CS = Crankshaft
F = Fan pulley
Gen = Alternator
T = Tensioner pulley
AC = Air Conditioning
PAS = Power Assisted Steering

sounds more like a air control /sensor but its difficult to diagnose from spain without seeing the car ,sorry for being able to give a quick fix

Hi, The carb is gummed up from sitting. The best solution is to take it apart and clean it. The starter fluid indicates that it has clogged jets or stuck floats. The good news is that if it cranks with the starter fluid everything else is probably OK. Good Luck!
