W124 E200 Startup problem
Dear Brand Partners!
Has anyone encountered the following error phenomenon, and if so, what was the solution.
W124 E200 1990.
It starts normally after a cold job of several weeks.
Operation starts warm within 10 minutes of starting.
Operation does NOT start warm after 30 minutes, puffs two, stops. From now on, starting is not possible. (as if there is no ignition) Prolonged grinding, - occasionally - floor gas, torturous puffs, then difficult to start.
As for the replacement, set:
- ECU replaced.
- Fuel pump relay checked.
- Overvoltage relay checked.
- The two thermal resistors are fine. (20C - 2.2 Kohm 80C - 350 Ohm)
- EHA okay. (operating pressure 5.6 Kg / cm3 lower chamber 5.2 Kg / cm3) control current.
- Air mass resistance is good. Not worn. 800 rpm around 0.7 V.
- Fuel distributor replaced.
- Upper pressure limiter replaced.
- Idle mixing screw set. (best CO, most even idle)
- Starter electric injector is working properly.
- Idle engine clean, no need, good control.
It would be a great help if anyone still had an idea and I would thank you very much.
