Hey guys,

I just put the car back on the road and I'm noticing a hissing noise coming from the rear of the car which sounds like it could be the fuel pump. It sounds exactly like air being let out of a tire. I searched some other forums and most answers point to the fuel pump but I can't seem to figure out if this is normal operation or an indication that it's on it's way out. The pump is a Walbro 255 with stock wiring, I've been having problems getting the car to cold start over the past two seasons and I'm wondering if a new pump would fix this. Is there anyway to test that the pump is still working 100%? Let me know your thoughts.

Thanks.
