I've purchased a bosch fuel pressure sensor as I have a P0192 fuel rail pressure sensor circuit low input fault. The car is hesitant to start at times where it will rev out and then just drop to zero and stall. I need to catch the revs with the throttle and it will start. I've asked my garage to fit it and supplied a workshop diagram showing the sensor on the inlet manifold on the back of the engine by the death pipe. Problem being, he says he can't see it. I thought he may have been able to fit it from underneath the engine looking up from the back. He says he can see the death pipe but not the sensor. From my reckoning, from the back looking up it should be slightly off centre centre to the left. Or has the inlet manifold got to come off to fit it. Thanks Tony
