About 3 months ago i also posted a not starting discussion. Changed all 4 injectors and the car started fine, had some heavy black smoke but it started. Now the same problem with P1195. Can someone tell me where the fuel pressure control valve is located? I have already changed the fuel pressure sensor. When i remove a nut from an fuel line on the high pressure rail fuel will come out plenty and if i try to start it will spray out very strong. I ques the fuel pressure is good.
2 things i also noticed.
- 1 The low pressure fuel pump (near the tank) runs very long when the ignition is turned on, it seems that it doesn't stop.
- 2 When starting i measure a solid ground pulse on the injector but only about 0.8 volt on the +12V side. I removed an injector and cranked the car but it would not spray.
With quikstart the car starts right away. When cranking i read.
low pressure supply 310.20
high pressure rail fuel supply 8188.24
fuel pressure regulator current 0.95
engine speed 310
Hope someone can help me to get this sorted out. Thanks in advance
