My 87 gn dies after about 4 seconds of running. I don't think the fuel pump is kicking back on. I was told it will only come on after about 4lbs of oil pressure builds up. I want to check connections and if that doesn't do it, I will replace the sender and switch,but I can't find where they are.I have a haynes book that is about worthless! any help greatly appreciated!Thanks,Tyson
