1997 E320 no spark

My w210 will not start. I have fuel pressure around 55psi. I have injector trigger pulses (checked with noid ). I have 12v to the coils. I do not have a spark to the plugs.I don't have a fault code. I could use some help now. I'm trying not to throw parts at it,unnecessarily.
Thanks in advance guys!

Justme300e I think if you look in the DME out put code .Thats the fuel injector computer you may find a code that indicates bad CPS sensor..
But you can read all about this on this forum But might be faster to google search it .Put in Google search box - Mercedes - Benz W210 Crankshaft Position Sensor Repair PelicanParts

I don't think that a crank sensor would help ,because I have injector pulse

Being the injectors fire, the CPS is doing it's job.

What is the history of this car?

These coils are waste spark so one end must be connected to a spark plug or ground for the other to fire.

Use a incandescent test light when looking for 12v , when using a digital meter a bad connection will show 12v but if any sort of load is applied the voltage goes away.

In another thread, someone lost the ability to talk to the ECM, it turned out that a ground was dirty. ( MB puts a bunch of grounds on the same terminal compounding the problem.)

Hook a test light across the injector plug to see if it still flashes.

If you swap ECM boxes, you need to get the DAS X module behind the speedo and a key that matches both boxes otherwise you will get a no fuel no start condition.
