My rabbit's been broken for a while... starts and runs, rpms jump around and it has no power (bucks around if you try to drive it). Seems like it runs better when it's cold.
I've replaced both fuel pumps and I'm trying to find the actual problem. The main external pump still makes a very loud whining sound. I also put some Heet in the tank to try to clean the lines out. The loud pump makes me think something is restricted or blocked somewhere.
I don't have a pressure gauge. I'm thinking of trying a new Warm up regulator.
Do you think a faulty or restricted WUR could cause the pump to be noisy? I'm not sure to what magnitude it affects the fuel pressure.
