XC70 Wont start after replacing fuel rail sensor
Hello!
I am new to this group and need help. I recently had ignition coils and spark plugs replaced after my 2011 XC70 died and would not start. They said the wires were "fried" and you could definitely smell burning plastic. A few days later, check engine light came on. The code was P0091 for fuel rail pressure sensor. Car was running fine. the light went off the next day. I called the dealer and they said not to worry about it if the car was running and starting OK. They said their would be warning signs, "hard starts,etc", of the sensor was starting to fail.
Last week the check engine light came back on. The code was again for fuel rail pressure sensor. The car was starting and running fine, but I decided to replace the sensor just in case, just to be safe.
The dealer replaced the sensor. About an hour after picking the car up, it died and would not start. It would crank but not turn over. The car had been running fine prior to replacing the fuel rail sensor.
The dealer towed the car and after looking at it for a couple days is telling me the fuel pump needs to be replaced.
They said it was probably just a coincidence the fuel pump went out after replacing the sensor.
I don't believe in coincidence and am wondering if it was something hey could have done? They said it was also possible the fuel pump was bad and the sensor was fine? In that case, they would not charge me for replacing the sensor.
I asked if it was possible it could be a wiring problem, fuel line, etc. They said they wont know for sure until they take out the fuel tank. They are quoting me $2600 to replace the fuel pump!
I find it very odd that with the exception of the check engine light coming on and (then going off), the car was running fine, until they worked on it and replaced the fuel rail sensor.
Please help! Your expertise and advice would be greatly appreciated! Thanks!!
