No spark

Moin, I hope that someone can give me a few more tips: Omega A 2.0i, built in 1986 with about 150,000 original km, no immobilizer. I used the search function but found no solution. Now to the error: the engine said last week that he simply did not want to go out. At the start attempt (so only ignition) the engine control light flawed and then went out. The yellow angels came and said that the crankshaft sensor certainly gave up the spirit, since also no spark of ignition there is – not on the candles and also not on the ignition coil. So: new KWS built in, OMI ran exactly 2o minutes, the same effect: engine out, no spark of ignition… After 1 hour waiting time: new start attempt, engine runs about 2 minutes, same effect: engine out, no spark of ignition…. That’s just the actual condition now: the guy doesn’t start. Unfortunately, there is no ignition coil with the junkis in the vicinity, OMI is probably already too old… I wil and can’t 100d I doubt that the good will succeed. I am grateful for every reasonable tip that somehow leads to success and include the helpers in “my night prayer”. HILFE paulchen27
