Audio 500sel starting problems when it's hot or after filling petrol

When it does this hard start buy and keep a can of spray starting fluid in the car, spray it into the engine air intake, if it fires right up you have a failing fuel pump.

My 1993 AUDI 500SEL 2.8 V6 is swinging but won't start, . A mechanic said that the module was broken I replaced but is still no difference, apparently there is no spark on the spark plugs an injectors

depends on the module he was referring to
it could be the ignition control module but it could be either /or both the cam /crank position sensors , the immobilizer module or ECM unit
BUT would be best to have the fault codes read first and then fix the problem/s that are found

I have an audi 500sel 93 manual AAH Engine, no fire to the plugs, car refuses to start. checked computer box, 2 crank sensors, modulator, the coils all tested okay and fuel coming to injectors ok. timing...

We will star a list of what is good.and what controls spark
1. crank sensor .you done it
2.ignition control module. located on the center of bulkhead,behind intake air hose
3.coils. you tested it.
4.ECM located under passenger side foot well

ECM no you got fuel,so lets leave it out
cranksensor okay you replaced it
ICM ignition control moduel.
no spark you cover everthing. has to be a loose or no contact connection somewhere, you covered it might want to tap on the ecm., or check the fuse for power to junction the ones in the hood area those can blow and not give power to ignition system

Puff-puff sound comes after fuel pump repaired/cleaned !!!

It can happen some times their are few possibility for such problem to happen a few day ago we had see such problem in Hyundai Santro Xing this sort of problem can happen due to
1.Failure or less pressure flow from the Fuel Pump motor which is located in fuel tank.
2.It can happen due to inflated fluctuated current supply from Ig Coil in simple term Ignition Coil
3.It can happen due to faulty spark Plug where it time to need to change those faulty Spark Plug while Changing those spark plug do go for spark plug such a NGK or Denso this both company Spark Plug are or Good Quality they give your car the better performance, Mileage fuel economy efficiency .
make sure that if you are replacing Ignition Coil then better replace 3 things at a time Ignition Coil, Spark Plug, & Plug wire set.
& do remember to replace Spark Plug at every interval of 10000.Km.
in this case you better consult to an authorized Hyundai or KIA motors service workshop where your problem will be sort out hazard free.

Petrol ron95 or ron97 is better for sport car? Why?

Most modern cars can use either, the computer systems adjust running parameters to suit.
If you are after maximum performance capabilities of the engine and maximum fuel efficiency, use the higher rating.
