A number of conditions may cause DTC P0087 and DTC P1093 to set:
1.Excessive fuel return to the tank
2.A fuel injection pump failure
3.A fuel pressure regulator (RPCV) failure
CONDITIONS FOR SETTING THE DTC
The difference between commanded fuel pressure and actual fuel pressure is more than 20 MPa .
or
The FRP Regulator Fuel Flow is more than 15,000 cubic mm at 800 RPM, or more than 36,000 cubic mm at 2,000 RPM .
If you have a scan tool or any way to data log, watch both of these and see what's going on.
