Ok got the engine in and all connected however when i turn the key it tries to start but wont ( I suspected not getting fuel). So I listened for the pump but heard nothing. However I noticed a buzzing coming from a relay under the dash. I removed the relay and it says main relay on it. I tried to replace it with another and still it buzzes. I belive it is the main fuel relay has this happened to anyone else? Help plz? Do i have to rewire?
