Hi, just my opinion, if you suspect a fuel issue, I'd use a fuel pressure gage, first. Around here some of the national brand autostores used to loan out a fuel pressure gage, if you don't have one. Next, I'd want to check good voltage and ground, at the pump connector, proper terminals, engine cranking. You need to drop the tank to replace pump,if pump is the problem?
