Trying to nail down the source of the problem. Ignition turned to on and no fuel pump hissing noise. Needless to say it wouldn't start after that. If I turn off the ignition and whack the fuel pump couple times, then usually the fuel pump hissing noise would come back and it would start. Need to know which terminals to jump after removing the fuel pump relay and/or OVP relay when it does die. Sometimes it would just die while driving. Or do you guys think I just need a new fuel pump?
