Brumby Fuel Problems

B RUM B · Post by **B RUM B** » Sat Apr 30, 2011 10:33 am

Recently bought brumby with EJ22

Wiring loom earths out and drains battery (manual disconnect switch since fitted)
Alternator pulley shaft was bust so battery would not recharge (fixed)
The fuel line out of the fuel filter near the fuel tank loops around back into the fuel filter.

Possibly bought a lemon

Strange thing is car can drive fine one day, next day (most days) after sitting at 6-70km in traffic when slowing down engine seems to starve for fuel, won't accelerate then bunny hop along till i pull over and let engine idle for 5mins or so. Yesterday the car started to cut out at low rpm at every roundabout or intersection

Any suggestions? given that the loom is obviously leaking juice is the problem likely electrical or finger crossed the fuel lines need a rework and clean?

Need to check fuel pressure with a gauge and try drive until it does it, sounds like a fuel pump on its way out. If a wire earths out that is likely a short, no? which would blow a fuse, but not drain battery ?

I would hazzard a guess that something has been wired to have power without the ignition needing to be on, which would cause the battery to run down.

A short in the harness should blow fuses (should)

do you have an ampilfier for you stereo? if so check how that is wired.

I would be checking the fuel filters in the engine bay and any other that might be on the fuel lines.

Check that the rear fuel filter isn't blocked

The battery leak I can live with for the moment, just need the car to be reliable for 5 days straight and the disconnect solves that problem. No amplifier unfortunately, no radio either.

99% sure there is a liberty fuel filter is in the engine bay, and connected... will check condition and tighten hoseclamps tomorrow. There are two other disconnected fuel filters, one in the engine bay with one inlet two outelts and another by the rear tank (which fuel hoses loops around on itself) which I believe to be from the EA81.

The car had run better for a day when I reconnected the electrical cables to the fuel pump, fingers crossed is just a poor connection and will give terminals thorough clean tomorrow. Fuel pump is noisy, was starting to think the filters had been bypassed to improve pressure in the line but don't believe the guy who sold the car is or would be that dodgy.

Is there another pump/filter in the brumby fuel tank? Drained the fuel and had a look inside, nothing I could see and no pump/filter attached to the sender unit.

So hoping it is just a dodgy pump/terminals.
