Poof! Out of the blue. Backed car out of garage left it out 4-5 hours. Started it to put it back in and car wont run. Cranks then surges up then conks out. I replaced the fuel filter app 5 months ago. Never had a fuel pump go out that fast, usually a fuel pump will start acting up when hot. Could it be the relay? If so where is the relay located on a 1998-E-320? NO CODES Thanks, Jack
