Your heartfelt plea has caught my attention- my advice: stop guessin' and take it to a professional mechanic- the money you've already spent would have paid for a repair by now, and saved you aggravation-

Thank you i'm located in France. The car is at a Professional mechanic.

You need to replace the distributor! The reluctor has failed. My '92 had this problem. It was especially puzzling because everything else(including the pickup coil) tested perfect! On a distributor equipped vehicle, the reluctor is akin to a crankshaft sensor on later models. It generates the spark signal. No signal, no spark!

Find out if it is fuel or spark that it causing the problem, try spraying a little starter fluid in the intake, if it fires then it is fuel related, if not then check for spark at the plugs, no spark means ignition system problems.
