I have a 2004 crossfire limited. My fuel gauge sending unit is faulty. Ot reads a half tank although full and reads empty even though it will only take 5 gallons. I know its full because i remo ed the sending unit to put in a new one (which was the wrong one). I reassembled it until i got a new one. I was driving and shortly after the light came on the car started losing power and then died and would not restart. I added 2 gallons and it started up and ran perfectly. My question is could this false fuel reading tri k the ecm to shut down? I got 2 codes P0453 and P0151.
