ok so i think my main relay is bad on my hatch. my brother purchased one today and of course there are 3 different relays to chose from. he bought the biggest one. can anybody tell me which relay would control the fuel pump. i have looked in my haynes manual and have done some reading but have not got a specific location yet. would someone please shed some light on this for me like where it is and how to make sure we have the right one. the fuel pump does not prime and the symptoms leading up to this seems like the relay to me. any help would be appreciated.
