Fault: Sometimes the fuel pump does not work when starting the engine. In this case, the engine was switched off after 1 second. I had to turn the key several times. After some attempts, I could hear the fuel pump and start the engine. When the pump was in operation, it did not stop after a short time.
Solution: I opened the relay and found a burnt resistor. Only the first ring was visible (looks orange or red). By the measurement, I received values of 2-10k. The first ring red means red = 2 and orange = 3. Therefore I chose a resistor with 3,3kOhm. Now everything is fine again. The fuel pump works at the first turn of the key and stops after one second. The engine works well 🙂
