My motor went in slow mode, off and didn`t wanted to start at all.
Found out that negative from ECU to injectors was not coming, positive from the main relay was ok. Checked harness and all outputs from the ECU, all working fine except the negative to the injectors. Checked all sensors too, I decided to remove and Map sensor. Without the map sensor the motor started and when installing it back the motor stops. Can someone pls help me understand if the problem is coming from the Map sensor before I buy a new one.

thanks a lot. My model don t think it takes an Hds. I have checked the return voltage and its showing 2.9volts. According to step in the map sensor section its a temporaly failure. So i thing i have to replace it.
