SOURCE: 1995 AUDI 90 CS - Hard to start... spark & fuel OK

Have you tried replacing the starter? I know starters can go bad if the car is not started or run for a long time.

I am getting the same car, with the same issue.. it sat for 2 yrs and won't start.

My mechanic told me it is probably a starter.

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.

SOURCE: 1999 audi a6 wont crank sometimes

Either there is a bad or dirty battery connection which is allowing the lights but no crank or you could have dirty or loose starter wires or starter relay may be bad or ignition is a possibility. All these can be tested with an ohmmeter for power. I would start with connections

My vw car Audi Q7 is having problem of mix of both water and engine oil, know the car is not Starting and when diagonis it gives code UO 101 lost of communication with tcm.plshow can I solve it.

If it was running fine before, I wouldn't worry about the U code. U codes can be caused by changing the battery. Your water and oil mix needs fixed. Intake or head gasket is blown.

2001 Audi A6 2.7T...Ran it out of gas. Now wont start. At first could hear fuel pump run for couple seconds with key in on position. Now fuel pump will only run when cranking. With key in on position...

It's very likely that you burnt out the fuel pump. The fuel pump needs gas running through it to keep it cool. If there was no gas and it's pumping air they tend to burn out very easily.

1992 mercury sable will turn over but wont start

Make sure battery has a full charge. If it cranks good but won't start, check the basics. Have a helper crank it while you visually check for spark at the spark plugs, if spark everywhere, use a gage and check proper fuel pressure. I looked at info for the 3.8L engine, 35--40 psi. Also, after you build fuel pressure, turn off the key, see if fuel pressure holds for a bit? If the pressure drops like a rock, check for fuel pressure leak. Check the vac line for fuel pressure regulator, if it has gas in it, the regulator is faulty, or a leaking fuel injector. The pressure could also drain back through fuel pump.
Also, check fuel injector pulse, engine cranking. Any applicable trouble codes?
Smell of the crankcase oil dipstick, if it smells like gas, either you don't change oil and filter very often or the engine is running very rich for some reason.

I have a 1989 dodge ramcharger 5.2 318 TBI it was starting up and then it would stall as we were driving then sometimes it will start and sometimes it wont i replaced ignition switch, starter relay,...

It sounds like you have an enemy that sabotaged your vehicle. The sand in the oil pan concerns me the most as major damage can be done in a short time with the engine running. The water in the gas tank is less of a worry because you can drain the tank and then add a couple bottles of Heet fuel conditioner which will cause any remaining water to mix with the fuel and burn away.

2004 audi 1.8t overheats no oil in water or water in oil tank bubbling away could it be water pump?

If the radiator has air bubbles it usually indicates a blown head gasket. It sounds like it has blown between the cylinder and the water jacket, this will cause overheating and pressurizing of the cooling system without mixing of fluids. A garage can check this by putting a pressure gauge on the cooling system. It is advisable not to drive too far, as if it gets worse it can fill a bore with water which can Hydraulic on start up and do some serious damage ( bent conrods etc ). Waterpump issues are usually leaking seals or noisy bearings, it is unusual for them to stop pumping. If the Head gasket is blown it wont hurt to replace the waterpump while the engine is in bits.

Do a three-part Seafoam treatment to see if it helps. You can buy Seafoam at a parts store or in the auto section of walmart. Get two cans.

Pour one entire can into the gas tank. This will clean the tank, lines, filter, injector pintles, etc.

With the other can, pour half into the oil, drive 60 miles or so, and change the oil and filter. This will remove oil sludge, varnishes, and deposits.

Remove the vacuum line from the vacuum pump on the back of the engine (or any other vacuum line into the engine), start the car, and with someone holding about 2000 RPM on the engine, allow the engine to **** up the last half can of Seafoam. It will stumble and run rough. Let it run for about 10 seconds after the Seafoam is sucked up. Then shut it down for 10-15 minutes so the Seafoam can go to work breaking down the carbon deposits in the engine's vacuum system. Then restart the car, let it idle for a couple minutes, then rev it several times to 4-5000 RPM. You should be seeing a LOT of smoke out the back of the car. Let it idle again and rev it up every couple minutes. Do this until you're not seeing much or any smoke. A little bit the next time you drive is fine - it'll finish burning off.

I've done this on many cars (most of them Audis) and it's made nice differences in smoothness, economy, and a little power even.

Also, make sure your other fluids are topped off, your air filter is clear and clean, the tires are inflated properly, and that you have no stored codes in the computer (stop at AutoZone and ask them to scan the ECU for codes - some latent codes won't trip a check-engine light but can alter the car's performance).

Wrong gas

Since it's not running right I'm assuming the lawn mower is a 2-stroke and the gas had pre-mix in it. It probably just got a strong mix of the pre-mix in the lines and just has to be cleared out. We run some of the old pre-mixed gas from our dirt bikes in our trucks to get rid of it. I put a gallon or so per tank refill of good gas. You may try and rev it up a bit when starting to keep it going long enough to flush it out with the new gas you put in, that or start it a few times till it's clean. An octane booster or fuel injector cleaner might help also. If the lawn mower gas wasn't pre-mix it may just be old and possibly have some water in it.
