After 11 months of nobody knowing why my car wouldn't start and having dealers replace everything from the switch to the security module. the chevy dealer is now telling me its the fuel pump. I've spent $1100 so far and now they want $850 to replace my fuel pump. I could get others to do it for $600 but I don't have the money. I want to do it myself. The instructions on the internet seem like it should be something I could manage but there is no video or illustrations. Does anyone know where I can find an online video or manual with illustrations for replacing a 2001 impala fuel pump.
