My audi 500 turbo have got a fireing problem.It run normally without any problems but then I decide to change the fanbelts while I was busy with that I also decide to clean the motor a bit.I rinse it

If the timing belt is damaged(broken or missing teeth) you will get no spark. One easy way to tell is that many times the engine will sound different as it turns over, than it used to.

SOURCE: WILL NOT START ALL THE TIME

Had the exact same problem with my 240 wagon. There is a temperature sensor up near the manifold on the drivers side of the engine. This is not the temp sensor that feeds the dash gauge, but one that tells the engine control module whether you are starting hot or cold. Mine was cracked, so the engine computer would get a cold start signal even after the engine ran warm, and would flood. This can be a difficult problem to diagnose and an expensive one when mechanics start swapping parts. You cannot see this sensor, but you can feel it (when the block is cold, please) right under the exhaust manifiold. A replacement is about $80 plus labor. Even my very experienced Volvo mechanic overlooked it. But the car would start and run fine, then leave me stuck when I tried to restart it. After calling AAA for a tow, the temp sensor would reset, then the car would start normally. Cheers. The 240 is a great car - I ran mine up to 235,000 miles; now I have a 740 with the same engine.
