Hi is there somebody that can help me, my s124 230te wont start it just cranks, it has no spark, this is what i have changed during this process.
Sparkplugs, ignition coil pack, rotor and distrubiator, the EZL and still no sign to spark.
i Wonder if it could be the crankshaft sensor.

Welcome to BW SirR,
Won't start is a broad term. Be specific ====> Crank, no start. No crank, no start?

Hello, the crankshaft position sensor should be the first thing to test. It is easy. just unplug it at the EZL (it is a coaxial cable with a round connector) and check its resistance it should be between 740 ohm and 820 ohm depending on engine temp.
Also make sure your coil is energized check if it is getting 12v (measure the voltage between th coil positive terminal and chassis ground) if no voltage then it can be a bad fuse or connection. the coil should have 12v when ignition is on and it is controlled by the EZL at the ground side.

i just measured the crankshaft, the result i got was OL open loop.

Then you found your problem. but make sure you have correctly measured the reisitance.
I once replaced my crankshaft position sensor by accessing from the top.after i removed the oil filter. it wasnt so hard to do it
Yeah thankyou. Yes i measured correct, i tried measuring the sockel on the ezl and it has connection there.
