Hello friends out there. We need help! Our E28 m. M20-B27 engine died a few days ago, and did not jump any more. We have since renewed the pump relay, because we believed it was broken. Was apparently ok. Pump ok, filter has passage, we also have the clamps 30 and 87 short-circuited and the pump ran clean. The control current +15, from the ignition lock, under the relay is also there. Strange: despite existing control current you have to tap the relay easily so that the P Ignition spark: is not there either. Distributors looked through, cap cleaned, rotor ok. Inductive sensor on the transmission is ok. Also the encoder on the flywheel is fine clean. Despite repeated start attempts the spark plugs are still bone dry! i.e.: no petrol, no spark. And the dung box does not start! The dare is very good in the shot and has almost 90,000 on it! All plug connections are finely clean and tested. Our suspicion lies with the control unit. The car doesn’t have a computer on board, so no immobilizer problem?
