x25xe wont start on my 1998 omega b
« on: 26 July 2025, 22:32:30 »
Hi,

Im almost certain I have to change the cranck sensor, but recently when I plugged the computer to the car I saw the strangest thing:

Engine Type,4 Cylinder
Ignition Coil Cyl. 1+4 (Cylinder),Load
Ignition Coil Cyl. 2+5,Load
Ignition Coil Cyl. 3+6 (Cylinder),Load

Is this a thing?  :o

I cleard all the fault codes and the reason no crack sensor fault is on, is cos I've tried an inferior one but with no results I have to aim for the better ones


Here is the diagnose

Dis pack failure?

It's definitely a 'thing'... They fail over time and they really don't like water.

Simple test for crank sensor is with diagnostic interface, look at live data for engine rpm signal. Should be 300ish rpm when cranking over.

What's the Delphi part number? Might it be SS10809?

In that case it is an incorrect part. The resistance is incorrect @ 0.59kΩ. The original Bosch part has a resistance of 0.86kΩ.

The correct GM part # for your car should be 90540743 which is Bosch part  0-261-210-131. A factory original sensor will have both those numbers on it. Sometimes GM parts also have a parallel factory production part number, in this case 90494182. Cadillac and Saab use the factory production part number as the spare part number, but it's still the same Bosch 0-261-210-131. This sensor has an oval sided connector.

So have a look at the sensor you removed in the first place, if you still have it? I expect you'll see a Bosch logo and 0-261-210-131 on it.

Be aware that Bosch no longer manufacture these sensors in Germany. They are now made in Slovenia, if they're still made at all. Even the GM special order ones that were available until a few years ago are the Slovenia parts.

New dis module installed and the same 2 and 5 cylinders.

Could it be the leads?

Which leads did you swap?

3 and 6 might not reach 2/5 and like wise 2/5 might not reach 1/4.

If you don't know when they were last replaced, that's probably your best starting point..they do degrade over time.

I'm afraid is not about the leads at all.
I.e. I removed the 5 and put the 3 in its place instead, leaving the 3 null and ecu presented the same readings 5+2

This is something else don't know what tho
