there is a blinker unit wich i do believe its in the fuse box under dash. it should have 3 terminas

well the last answer was almost right if you have a standard tranny if so it has a hydralic system which uses brake fluid and you probably lost the fluid for the slave cylinder which engages the clutch.

first off you need to see if you got spark to those cyl. if not probably bad coil. if theres spark then you need to check injectors. if injectors are good then head gasket would probably be blown. especially if both cyl. are together. good luck
