The MB specialist has checked compression and they found 2 cylinders being down on compression but this in my books should not stop the engine starting.
They have replaced the park plugs, I don’t know with what made.
The fuel pumps are new and both run on prime, fuel comes out from the injectors.
The car was running without a problem and one morning it refused to start. So I do not think is an air leak.
The issue is that the MB specialist can not start the car and is sitting in the garage since Jan 2023. Before that tried to start the car by the usual means, easy start on the intake etc. Checked that I get fuel on the engine, sparks, distributor, cables, crankshaft sensor, without luck. I decided to send it to a MB specialist and its seating there since then.
Now they are waiting to get a donor car in so they can swap thinks over and find what it wrong with it. Personally I don’t think they have the will to fix it hence not doing much on the car. I need a competent mechanic that can solve this issue and put the car back on the road so I can use it.
