Toyota brevis 2JZ-FSE d4 engine runs then shuts after a while drive.cools down then starts again.and not a over heating proublem

You have 2 sensors for engine temperature one tells the gauge on the dash board what the coolant is the other one ECT. SENSOR tells the computer what the temperature is.If the ECT gives the wrong information to the computer it doesn't matter what the temp. gauge reads .
It's a common problem they go bad .It works like this the hotter it gets the easier electrons flow through it. The colder it is the more residence their is because its colder and the electrons move slower through cold materials that's how it works .

Toyota voxy 1az-fse will not start, fan running continouosly, no spark, replaced ecu, cam/crank/temp sensors

Check for spark at the plug when cranking it over with a screw driver the spark should jump off the screw driver to earth,hold screw driver close to metal.

Toyota diagram cruis control

The cruise control on modern Toyota vehicles is built into the ECU.
You may only need to install the stalk and the wire jumper that connects the stalk to the spiral cable, but some vehicles are missing the wire that runs from the spiral cable to the ECU. The parts are about $110.

Engine Problems

There is no 3c engine in a Toyota Supra. If you have a 1995 it would have a 1JZ-GE, 1JZ-GTE, 2JZ-GE, or 2JZ-GTE if you can tell me which engine you have I can further assist you.

Re wiring

Thanks for your concern guy's. We did manage to fix the problem....It took us about four days of laborious work....We had to remove the harness covers and work our way backwards and forward, from the management computer, to and from the relevant 'sender unit' coolant temp, air temp, manifold pressure, lumda and oxogen sensor and from the controlled units, ie, ignition system, injection system, cooling fan set up and so on. We managed to identify the connections by following the identification labels printed onto the circuit boards.

We think that Toyota could make life a lot easier, if they used a standard wire colour coding and did not change that colour inside the loom....It is not un-common to see, as an example, a red with white tracer at one end and that may be joined to a blue with red tracer at the other end....If the loom cover is not removed and the cable inspected, you could not guess from what goes in, what will be coming out.

Hope this will be of help to someone somewhere.

Best regards
