My 04 Mercedes C32 AMG will no longer start. I can hear the fuel pump hum when i turn the key on and the engine turns over. Once in a while i can get it to start but when it does, it spits and sputters and nothing will happen when i press the gas. B4 it got this bad i took it 2 get a scan and it said something about a vapor issue and that i needed to replace the gas cap. I didnt at the time and now that its not drivable, i dont see that being a fix. I checked the fuel pump fuse and it was burnt so i replaced it but even b4 i did, i could still hear the pump hum. B4 i throw money at it, i wanted to get opinions first. Is it the fuel pump? The gas cap? A fuel pressure regulator, some type of sensor?
Also, if it IS the fuel pump, my part number says it's a $1200 replacement. Would any other part numbers fit that arent that expensive?
Thank you in advance for anyones help.
