got a crx shell with a a6, it wont start. it gets fuel, and spark. the owner had said it had a blown headgasket, but i checked the antifreeze and it looks to be clean and the oil doesnt seem to have coolant in it. also he had said that he was driving it and all the sudden it just shut down. car turns over but wont start. what could it be, possibilities? timing? main relay?? idunno help please!..

 

If it gets fuel its not the main relay. Check the timing and also do a compression check on it.
