Attesa Pump Making Very Bad Noises

Some of you may have followed my manual conversion dramas. I've blown up a transfer case and had a driveshaft drop out and destroy a gearbox. now comes the next saga in my story.

I'm currently in a place called Turill, which is just off the Golden Highway north of Ulan in NSW.

I was driving along, when my car started to lose power at high revs. I thought this was my coil packs finally giving up which i was sort of expecting after 215,000km. it got worse and worse, then i thought the car had turned into limp home mode for some reason, but it just lost all power and i had to pull over. the car was still idling, so it couldn't be that bad that the coils would only work on idle, so i figured it must be something else. as i got out of the car, i heard a terrible pulsing noise coming from the back of the car, right where the ATTESA pump would sit. I turned the car off, and the noise slowly went away, but not instantly. since i figured the pump was shot, i pulled the 4WD fuse out and went on my merry way thinking this will leave it in 2WD and i'll be right.

10 minutes later, the symptoms come back. i pull over this time straight away (last time i had driveline problems i didn't, and ended up with a driveshaft going through my gearbox) and the noise is louder. I called the old NRMA, and after 10 minutes of them trying to figure out where the hell i was, they've sent a guy out to help me.

Questions: will the ATTESA pump shiting itself cause the car to lose all power? Also where is the fuse/relay that kills power to the pump? i pulled both the fuse and the relay out of the fusebox in the engine bay and it still works.

I might have found out the reason my last 2 gearboxes didn't last that long, perhaps my attesa pump has been playing up since the manual conversion and i just haven't noticed until now.

Has anyone who has done a manual conversion left the standard computer in? all i've done is connected the reverse wires from the gearbox into the fuses but left the neutral wires unconnected. someone said in passing to me the ATTESA computer uses the neutral for something, but i don't remember what. when i first did the conversion i didn't think it was needed, and told it wouldn't work with the auto computer to have neutral connected.

any help would be appreciated, thanks guys.

Well i'm looking a bit red faced. I thought because my gearbox was playing up that it was a gearbox related problem. turns out i've put some shit fuel through my car and its wrecked my pump and filter, so i'm getting towed home from Coolah to Bathurst.... I'm getting used to travelling care of NRMA, maybe I should just do that from now on. Now to find a new Bosch 040 to replace the one I only put in 6 months ago, bugger.

yeah, problem with that is i bought the thing about 2 years ago and never fitted it until now. it sucks, but what can you do.

I don't think it was directly the dirty fuel, more the dirty filter clogged up wearing out the pump bearings.

You have singlehandedly raised the cost of NRMA memberships by 3% in the last 4 months! :)

Good to see someone getting their money's worth, though.... Tough break about the fuel pump :D

hehe, I sure have. I've been towed from Sydney to Bathurst, and now from Coolah to Bathurst. I'm glad I have Premium membership, that's all I can say.

I've bought a new car already so I can properly attempt to sell the Stagea, so I can just fix this in my own time now.

      Cas issue

      By GTSBoy · Posted

      The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.

      RB26DETT Sketchy boost mod?

      By Duncan · Posted

      Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.

      Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.

      boost source Size Garrett gt28 gen2

      Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
