Hi,

My ST170 is throwing up a fault code P0190 - Fuel Rail Pressure Sensor Circuit Malfunction.

The car appears to have a massive fueling issue, as the car is basically undriveable. I had the fuel pressure and fuel flow rate checked and there is 30psi of pressure but basically no flow.

Has anyone had a similar issue? And was a new fuel pump the solve?

Any help would be greatly appreciated.

Thanks,

Damion
