Has anyone ever had a Walbro 340 fuel pump kind of crap out on them? Mine is practically brand new, less than 1000 miles on it, and it's just about dead. When I installed the Walbro, it whined significantly louder than the stock pump, probably twice as loud or so. The whine has gotten progressively louder and now can be heard inside the car at freeway speeds. The engine has started to starve for fuel at anything over 10 PSI.
I checked my fuel pressure, it's 38 with the line off, which is pretty much where it should be for a stock car like mine. My fuel pressure gauge won't reach the windshield, so I can't go for a ride and see what the pressure does when I give it some boost, but I am almost positive that the engine is starving for fuel. Today it got so bad that I didn't think I was going to make it home. Anything more than about 5% throttle and the engine would stutter,stumble, and try to shut off; and now the fuel pump is louder than it's ever been.
I checked the voltage on my hotwire kit, I've got 13.9 V at the pump, so I don't think it's a wiring problem.
I guess it's possible I just got a bad pump, but I'd like to hear from some people who are little more knowledgeable than I am about it. Anyone have any experience with something like this?
