I change head gasked put the head back together now the car wont start. When turning the key just before I crank the engin the Main Relay makes an awkward short buzzing sound. Replaced Main Relay with a brand new one and it is still making this sound. ENGINE IS NOT GETTING FUEL, I put starter fluid and crank and the engine runs fine so I believe nothing is wrong with the timing. ANY HELP WOULD BE GREATFUL.
