This car has been a nightmare from day one! First off when i bought the car i would not shift out of first gear after being in a front end collision but still had reverse! So i figured i would have a TCM or a Transmission all together! After sending it to a mechanic they figured out it was the transmission and put a rebuilt one in! after the transmission was replaced i guess the battery got disconnected the car would not start! The following parts were replaced fuel pump,fuel filter, ignition module,Ecu,! I have no spark and no 12 volts going to the fuel pump! I had another AC delco mechanic look at it and he said the body cpu and the Ecu are not communicating with each other! He said i have to take it to the dealer to have it flashed is this true! any feed back would be appreciated thanks allot!
