Good morning,
My wife has a 2004 Volvo v70 non turbo. The check engine light came on last week and the car started hesistating. I put the OBD on it and it came up with p0192 Fuel rail. The CEL reset and was fine for a few days then yesterday it came back on and today the car wouldnt start. She got it running then home. Should I replace the Fuel Rail sensor and hope thats the problem? The part is $170 but looks easy to replace. I just dont want to start changing out parts and not fix it. Thanks!!!!!!

 

Check your EVAP system. and make sure the gas cap is not worn out. Sometimes, that is all it takes

 

P0192 - Fuel Rail Pressure Sensor Circuit Low Voltage

After googling, found this; have you had this recall done?

Thanks......yes I checked on recall but (of course) my vehicle is not one of the ones affected!

 

Regarding your first post; that's probably not a bad guess, but it is still a guess.

If it were me, i would attach a fuel pressure gauge to it and drive it; really need to know what the fuel pressure is doing when the engine is acting up...

If you're interested in trying this, make sure you don't take it lightly; this obviously can be dangerous if your attached fuel gauge springs a leak!!!
