My car wont start but only cranks, what can it be? i provided details on page. on 1992 Mercedes-Benz 300CE

I changed the breather hose and lost where the extra little hose on it connects to. finally found where, and i then took off 2 wires to distributor cap for inspection. I put them back then car wouldnt start. I changed ignition coil, spark plugs,cap and rotor which were very bad condition, car still wont start,cranks but wont start. I noticed the engine fan stopped turning.Now im sitting for three!!!!!!

all you do is replace the Crankshaft position sensor which is situated in in the back of your engin, then you problem is sorted out, i have done that my self and advised many who had joy
Thank you for your response! sounds possible, i was told it maybe my ignition module which is a fortune for my module, but i'm not sure and don't want to save up to get that especially if its not the problem. there's no electricity reaching the ignition coil, i changed it and the cap and rotor and there's no spark in the wires. you still think its the crankshaft sensor?
100% CPS, it cost around $55.00 and you can fit it your self, it is a bit small place behind the engine, but i am sure you will manage
ok thank you very much for the information i will try that!
