Audi A6 C5 2.4 V6 Engine Shut Off: Spark, Fuel Pump, Timing, Compression & Sensor Troubleshooting

As in the topic, when parking in reverse, the engine went out as if someone turned the key, some data:
- spark is (elegant on all pots)
- tensioned (changed 7,000 a year ago, has all teeth turning the wheels) not checked exact setting because there was no longer time to remove the front
-gas established half a year ago, there is no possibility of emergency firing from gas (so installed, cuts off the electricity during spinning)
-the fuel pump works gives nice pressure, candles wet and smell of gas after a short spin
- error was 17800 repeated after prolonged shooting, the sensors and lower and upper (camshaft and crankshaft) were replaced
-immobilizer lets go + no errors
-the engine spins very quickly (there is no VIBRATION to ignite for a while) as if it had no compression but it's v6 so normal, the compression checked correct everywhere (only on one 7-8 bars the rest all right)
- on foreign fuel, such as rust removers or extraction gasoline, do not want to be demolished
-the driver on the pit, dry as a pepper zero marks so that moisture will ever come there, a car imported about a year ago from Germany

I know that from all that I wrote that the car must start, but unfortunately it is not so, if I do not run into anything by Saturday, you will have to get to the timing and check it, unfortunately Mr. Gasper has hindered the work because the hard cover will be removed engine (plastic), waiting for some wise ideas and thank you in advance

what else comes to my mind is:
- air intake,
- exhale
- candle coils

the exhaust falls off because the car turns quickly and the stink pipe, the spark is on EVERYTHING so the coil also falls off, intake hmmm, sucks air, you put the hand in the intake and sucks when turning

Or maybe you were refueling soon at some insecure station and there really was no gasoline around? Or maybe you borrowed a car and accidentally flooded ON? Did it work a bit until he burned the gasoline from the pump and lines and choked with diesel?
A few months ago there were also articles on the Internet about the fact that at a gas station (and not noname) there was a mistake and there was gasoline in ON dispensers and vice versa, so as you can see this option is also. If you have the opportunity to get some fuel from the tank or filter, then you can easily check - gasoline vapors are flammable, diesel is hard to ignite (e.g. with a lighter) without spraying with an aerosol.
