Can anyone confirm that the rail pressure sensor connector on the LB7 and LLY are identical.
On the LLY it looks like a Bosch part number, not sure about the LB7.
Any info on the LBZ also much appreciated.

According to SI, there is no FRP connector... Kind of odd...

The actual connector that plugs to the regulator is the same on the LB7 and LLY. It also matches the LBZ.

Eric.. Is there a fuel rail pressure sensor on the LB7.. Up on the rail.. The routing diagrams don't show it..
The fuel pressure regulator solenoid is there on the pump, on all three, but no rail pressure sensor on the LB7..

Could this be why the LB7's never 1093'd? The ECM didn't know when the FPRV popped?

On another note, I was logging today and P1093'd on a long 5th gear locked pull.. (unshimmed)..

After setting I noticed my rail pressure eventually did rise back up without restarting all the way to 23kpsi.... But the P1093 was preventing me from going beyond the 2000 rpm limit..

Never knew it would reset without taking pressure completely off it, but it sure did.

See post in LLY fuel system section for pics..

The rail pressure sensor on the LB7 is on the block that splits the fuel from the CP3 to the two rails. It also has the rail pressure regulator.

ok, first I'm a dummy, I was thing REGULATOR when posting
I now see the Sensor was in question.

No problem...
