hard to start usually is regulator problem....
but in my experience the real indicator of fuel pump problem is "loosing fuel pressure" on long run/driving...
since i've change the fuel pump with the turbine style pump...my fuel pressure have been pretty solid no matter how long the drive is...
the problem is common in gerotor type of fuel pump because of material which is metal and tight tolerance inside it....
especially with avs which is using same design as walbro...
just look up in mudah.my....i would say its quite cheap because not ori....
if want ori pump probably still roughly around the same price as DW pump
do you have any suggestion for fuel pump other than aeromotive?from the look of it at mudah.my, cant find any nearby in kl/selangor area.
looks like from the diagram i can peek into the pump to see whether it is metal rotor or turbine propeller.?
no issue on cranking engine..Just keep on Having lean on idle around 16 afr avrge, from cold start, and its affecting the whole rpm range..last time seldom get this figure, now quite frequent, be it cold start or after long journey.
dw a.k.a deastch-werk pump and injector works great also
yes u can peek inside through the bottom hole to see the pump type...turbine type u will see something like turbo fan blade.....
gerotor type u will see shiny metal pump like oilpump rotor shape
