Thanks Andrew. Have never heard the engine running. Bought it immobilised. Previous owner said it always started first time and problems only seem to have come about after lending it to someone. The previous owner has given up on it. It's puzzling the vehicle does not respond to EKA or the lock key in fob (EKA changed by someone; receiver and/or fob faulty?).
Thanks for the advice and photo Sierrafery. Will get the RF receiver off tomorrow. Has three wires coming out of it - one purple and two black. The one purple and one of the black run from the receiver straight into the passing wire bundle (loom). The second black wire starts out as thin as the other black wire, but after a couple of centimeters converts to a thicker wire with heat shrink cover over the join, then into the loom. In some photos you see an unused earth wire bound up out of the way - this RF receiver does not have that wire. Branded Laveo or Aveao? - will get better info once I get it out of the vehicle.
Thanks for the cheeky retort Steve.[wink11] Fun and games getting the liner off. The push pins on the D2 seem less brittle than those on the D1...don't seem to have broken anything yet. If it helps at all I've done two sagging roof liners (material separating from fibreglass backing), a D1 and wifes Corolla. Pulled the material almost completely off by 99.9%, just leaving one edge only just attached to help with alignment when gluing it back on. Before gluing I stiff bristle brushed off all the old foam. Used spray on Bear yellow contact adhesive - ignored the wait time as volatiles just flash off so quickly in this heat. You lose in theory the sound insulation quality of the foam this way, not that it seemed to matter. Don't put the liner back on as if you were throwing out a table cloth or bedsheet, rather gently roll it progressively forward without stretching it, targeting a match between memory shapes in the cloth and shapes in the fibre backing. You'll likely get some glue through the cloth. Otherwise you'll have to source new material with foam backing, unless the foam is still good on your original. If your vehicle is really an old banger consider painting it.
On Sept 5th I'm carrying out my threat to the vehicle to annihilate its security system unless it cooperates (I'm still going to annihilate it even if it does cooperate)[bighmmm]
Unless Sierrafy says the RF receiver is important in other ways then I doubt I will be pursuing a replacement.
Aim will be to see if there is voltage to the unit, dry solder on the board (think D1 window control board), corrosion, loose connection, chaffed wire. Hope is I'll find and remedy one or more of these and get it started. And there are doubts about the fob. If it can be got running then I need to register it locally so that I can then drive it 40kms into town to get the autologic programming done for key only lock and unlock, then drive home, then buy a nanocom. Otherwise it's flat bed unregistered each way for about $320 total. The cost of cheap cars start to add up.
Little concerned that the first battery I put in went from around 13v down to 10 over a few days. Have recharged it to 13.8 so will let it stand alone to see if holds charge. It's a red top optima about 4 years old (or more), and possibly open to suspicion at that age.
