Hi guys, i just got a friend to install a new head unit for me and now my car won't start, there was like no fuel in the car (only just managed to get home a week before CD player was installed) so not sure if he fucked up the wiring or if it the fuel, got a bad feeling it a wiring fuck up on his part because the car should start even with near to no fuel shouldnt it??, please guys really need some help, i need my car for work urgent and i have no other options and cant afford a professional to come look at it for me
