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.

      Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
