its behind the panel between the b and c pillar, driver side. and it is very unreliable after all this time. the easiest way to bypass it if it is your problem is to run an earth directly from the fuel pump negative to the chasis.

i have been having huge issues with my fuel system and have put it down to this!!! we have tryed everything else!!!!! so run a spliced earth straight to chasis in the boot somewhere??

is this the metal box thing thats similiar looking to the attessa ecu etc in size?

we are no looking at completely removing the module all to gether. has anyone dont this before? will it be stuck on high voltage all the time once the module is removed?

removed the module and ran a separate power supply to fuel pumps via a direct feed (relay controlled).

yes same...and no ill effects, although it is a race car it also gets road driven a fair bit.

and yes to answer the earlier question - just run it straight to a good earth in the boot somewhere.

Bringing this one back from the dead...

My car would run for about 30 seconds - a minute then cut off. I'd let it sit for about 10 minutes then it would fire up and run again for 30 seconds - a minute again. Eventually it just wouldn't start at all. 

Pulled the line off at the fuel filter and cranked the engine and confirmed it wasn't getting any fuel.

Just replaced the pump and the engine still isn't getting any fuel. Would this mod fix that?

Stock ecu, walbro 255, has been running perfect before this.

    • yeah I've never understood that either.... And to answer an earlier question, I write the date on open bottles and throw them if more than 12 months old (which they almost always are, because I don't need to bleed them unless I'm changing lines/calipers etc in between)
    • Nah, the one that hit the boot was a big steel locker, around 6 foot height, 4 foot wide and 2 foot deep, empty it weighs about 15kg and had about that amount of stuff in it The photo didn't give a good representation of the actual damage, the large ding on the passenger side was about a inch deep, the one on the driver was about 1/2 inch deep, right on the curve, where the inner boot frame doesn't let you get behind it with a dolly Basically the same issue with getting behind the damage on the centre of the boot We could have filled it all with bog, but my OCD would be triggered every time I looked at it, knowing what hides beneath  As for the locker, I did get the shits with it and put it in the scap metal bin, but, I pulled it out and it is now sitting in the garage at home full of car servicing stuff, cleaning gear and random tools, it's going to pay for it's indiscretions
    • Whilst I typically don't cheap out on things, if I can save some money, like $1000, on a clean straight panel, that gives me $1000 to spend on other stuff, basically free money really 🤔 🤣
    • Is the toolbox that damaged the boot seal the same item that fell on the car during the storm a while back?
    • Who are you to deny yourself? I’ve said this many times to myself and apart from getting what I really want, I go quiet for a while whilst working out what I just did to my savings and how will I afford what it cost, then, next payday…
