I went to the dealer with a P0193 and he said to me that the left fuel rail needed to be remplace because it have a little welded hole that block some fuel line when i need throttle !! So i remplace the fuel rail and the truck be OK for two days after this it begin to stall in 1 and 2 with the engine light on.........

I disconnect all the connector from the PCM and disconnect battery to reset the trouble code. It runs number one, two days but the P0193 reappear with the battery light on....

Someone had the same problem and know how to repair the trouble? I thing it's a wire somewhere was ground or broken but I don't know where the Frp is on the engine
Thanks!

If the truck is under warranty I would go to another dealer that knows how to fix the truck.

 

No warranty I think is the FRP sensor or his circuit in trouble. Where is the FRP sensor, i'm not sure!

FRP sensor is on the left fuel rail. FRP is on the front, Pressure regulator valve is at the rear.

 

It's the connection on the ECM it's loose!!
