Hello,
I've bought a manual swap kit from a fellow member of 190rev forum. Everything bolted right on, minor changes in wiring, driveshaft discs etc etc.

My only one problem thats left to fix is the car cranks but there is no spark, here is the logical route to elimination of the possibles... btw car ran fine prior to swap. Car is a 1987 190E 2.3 8v with 150 000km original/ no winters

-Checked all possible fuses on the car... all are ok
-Redid all ground cables
-Tried the Ignition module on another 190 ... it worked
-Changed ignition coil, did not resolve the problem
-Tried ignition coil from an audi 90. Did not start (same symptoms)
-Tried to see if there is fuel in the distributor, almost sprayed me

Now here is the one that sucks
Found that my crank position sensor is in the back (flyweel) and took it out, cleaned it, still no spark...

Here is my question, the seller told me the tranny and flywheel etc. came from an 87' 190e 2.3 (assuming he's not lying to me), mine is the same model year and engine type. How would i know that the position sensor is not working right or the flywheel would be the wrong one??? IT fit perfectly, the clutch works fine now, everything seems fine but i cant get her started.

On the automatic flywheel, i looked over and over and didnt see any sign of magnetic strip or anything that would serve as a sensor reading. What and where does this sensor point and read??? Also, what is the purpose of the crank position sensor in the front (the one that goes directly to the diagnostic plug) ???

Please help, what do i do???

I don't know at what part to respond to. I'll start at this, why in hell did you swap the engine out? It's no 16 valve and will never be a 16 valve, or a 2.6 six cyl. Why, was it bad, or are you looking for more power???? Clue us all in.
I think the thing you need to do is go find a shop that is going to work with you. Because trust me, you are going to need a shop that will work with you. The reference sensor is just a fancy enclosed magnet. It picks us the signal from the flywheel, that made from metal

Noo i didnt swap the engine, it is the original one, i'm just swapping trannies... form auto to manual...

Can anyone help me to find out how to make my older type flywheel work with a rear placed reference sensor???

You have to buy the right parts. Call your local dealer, they are usually good with parts. You put in a pilot bearing, right?

Check the sensor values...
Approx 900 ohms ..you are looking for .5v. at cranking speed.
if the sensor is working, the flywheel may not be indexed correctly [ which means you will still have spark, but not at compression stroke]

He may aslo have sent you a flywheel from a 16 valve engine[ 102.983].. they used the front sensor only. You have a 102.985.

Again , test the sensors ohms value and cranking output.. that will tell you if it has a good coil [ ohms] and if the flywheel is triggering it [ volts ]................

Ya well i have no spark at all, otherwise even if at different timing there was spark i should get some clunking or uneasiness from the engine
It just cranks freely as if all spark plug wires have been taken off... and also, i checked for spark with a single spark plug and grounded it... absolutely nothing.. nada...

The flywheel is from 2.3 8v supposedly and there is a split where from 85/86 transitionning to 87/88 models the sensor is in the back. I need to know how could i tell a wheel that would work for my car... what is the sensor reading... for sure its not reading the teeth of the starter. it has one position where the crankshaft is at TDC... thats what its looking for but how is this represented on the flywheel itself??

It should be triggered by a magnetic segment on the flywheel.
When that passes the sensor , you should get a voltage reading to the ECU .
Did you Ohm the sensor????????
