I bought a new one from Toyota, I think it was around £70. I can't find the invoice at the moment so I can't quote you any part numbers.

One goes to the front of the plenum, the other goes to the tee piece at the end of the IACV hose.

Hi, Sincere appologies David, I did reply to your last message but obviously forgot to click the 'send' button!:o I'll PM you now........

So you have voltage where you should have voltage and the fuel pump is running when the engine is cranking over, but is fuel actually reaching the injectors?

That's two pints now. :D

No, the ECU doesn't need to 'see' the switch. I use it to latch a relay for the fuel pump.

Short answer, no. The looms and ECUs are totally different.

Easy check, do you have ignition 12v at the +B terminal in the diagnostics port?

Hi guys, if you want to send your engine/transmission wiring looms (they're integrated as one loom and it all unplugs) to me I can prepare them for you for a fee. I modify them so that the engine/transmission wiring remains a separate unit with it's own fuses and relays and leaves the recipient...

I have two Spitronic ECUs here, one for a VVTi 1UZ with a manual gearbox and a M112 S/C, and the other is auto. I got to the calibration stage with the VVTi motor then had to put it on the back burner to concentrate on another conversion. I'll get back on it soon hopefully, but it's good to...

Excellent! This conversion is on my 'to do' list as soon as I can get hold of a 2UZ. Not readily available over here yet.

Excellent, thanks.
