Mercedes w202

I change my Mercedes w202 head gasket and now it doesn't want to start looks like it is throwing away the spark.

Have you got the coils and plug leads to the correct spark plugs?

What do you mean by throwing away the spark? Does that mean no spark?

If so make sure the crank sensor is plugged in also worth checking all fuses.

And maybe scan it for codes

Does yours have the lights in the mirror for the immobiliser?

We have changed the coils and crankshaft sensor with new ones every thing is on but car don't want to start we have seen that the spark what we get from the sparkplug is weak.

We have put the firing order like was before we changed the head gasket and no myne don't have lights in the mirror

Have you checked the timing?

Post up your chassis no- there are 2 different types of ECU which control the spark firing. PMS and HFM The first is a sealed unit the second can be repaired. The danger with engine rebuilds is the engine wiring loom gets disturbed and some of the early 202 cars suffered from brittle insulation
