  1. Not that hard. If the fault ever comes back i'll dig in the waterbox.
  2. Finally got around looking further in this; Cold start; remove pump relays and afterrun coolant pump relay, fuse in place - Start the car - Fuse blows immediately (no relays attached). BUT if I immediately plug in all the relays, and replace the Fuse, both air pumps start, fuse does NOT blow and all is well in the kingdom of waterbox. And it gets even more interesting; Last time I fiddled with these It seems to have cured itself, even though I did nothing?? My best bet is that the insulation on the control wiring is cracked or stripped in the waterbox, and moisture&dirt has bee
  3. New upgraded valvebody fitted and the car works like a charm once again. All The shifting issues are gone. Tranny took 8,7L of Redline D4. Many thanks for the write up.
  4. I have tested the pumps and those are perfectly fine. Jammed pump would drain a whole lot of current and most certainly blow out the large feed fuse for the relay(s). The problem I'm having is on the control circuit for the relays. The current present in the control circuit should be very minimal, therefore the 5A fuse. I would gues that ecm applies ground to the relays when the circuit needs to be energized, only thing that can blow the control circuit fuse is a short to ground between the fuse and the relay or a short to ground IN the relay. Failed coil in the relay would very possibly c
  5. Checked both relays, OK. Still blows the 5a control circuit fuse. Ideas will be appreciated.
  6. Found diagrams for the relays and fuses. Will check later today.
  7. Greetings from Finland Car is blowing the 5A control circuit fuse for the secondary air injection pumps and therefore throwing the P2259 code, it also has intermittent "brake booster fault" and I have a feeling these are related to each other. I'm suspecting an relay issue since the pumps are fine(tested) and the fuse is for the control circuit. I also removed and tested the vacuum pump for the brake booster and it's also fine. ' Has anyone had any similar issues? Where's the control relay located? I did look for info on the site (a great one!) but so far no good. I'm also looking
