So I figured I'd pump out all the crappy fuel that's been sitting in my tank for 6 years, instead of trying to start it and possibly causing other problems.
By the way I did it like this:
Disconnected fuel line going into the fuel rail (top hose), ran it to a portable fuel tank.
Removed relay (shown in Bentley and confirmed to be lower right/position 12, OEM relay marked with 167 on it),
And jumped the 30 & 87 terminals.
When I did that all I got was dribbles coming from my walbro (which was DEFINITELY working). So now I'm feeling confused about my primary fuel pump. Is it working and I just can't hear it over the walbro? Dribbles coming out because I'm out of gas?
Well, tested terminals 1 and 4 on fuel pump plug to confirm power (red/yellow) and ground (brown).
Pump clicks but that's about it.
Tried ye old hammer method to no avail either.
Now for one more test...
Remove outlet hose from fuel pump itself and repeat steps above to turn on pump. No fuel comes out.
Because I need to be 100% sure I'm not out of fuel (and it seems I need a new pump anyway) I remove the pump. There seems to be a couple gallons in there.
Measured it about an inch from the bottom of my socket extension.
So after I removed the pump I put power to it again and got nothing but a click.
Time to order a new pump.
Now it's just random stuff.
FYI in case you need a new sensor and have the AEM A/F Gauge # AVM-30-4100, replace with a Bosch 17205, or part # off sensor: 0258007366
Quick google of that part # shows its identical, including the harness.
I'm sure many new this already, just trying to document and help.
