hey guys

well I've had this issue for a short while now..

It sounds much like a loose pas/alt belt but louder. Its also not throttle related - sometimes I can fire it up from cold and it'll sit there and do it for 30seconds and other times I can drive for 20km and have not so much as a whisper then it'll just do it again.

I've tried wd40 on both belts it did nothing so I'm guessing its not a belt related issue.

I tried today to remove the pas belt and it the sound didn't appear once (steering was bloody tough tho lol!). once I put the pas belt back on and nipped it up I heard the screech again.

Has anyone had this issue? Would overtightening the pas pump belt cause it to screech at all?

sorry for the questions, the car still seems ok but the noise is just driving me nuts now lol!

When a belt starts to slip after working for a long time, i reckon it should be replaced. Also, belts need to grip - screeching is them slipping, so putting on a lubricant like WD40 will just make the slipping problem worse. I wouldnt expect it to be bearing, as that noise will be consistent not coming and going as you're seeing. Overtighening usually just makes bearings wear faster - AFAIK it cant cause screeching.

Have you checked the PS fluid level? (not that I would expect that to make the noise you described, but i dont have any good ideas).

      S15 Spec R

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!

      R33 Fuel Pump & Brakes after alarm swap

      Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
