TU3MC L/Z Harness Question

Post by rossnunn »

Right, so far things have been going along dandy. I have now worked out the pin out of the Multipoints two plugs that connetc it to the front enginebay harness but its on the Single Point I've hit a brick wall.
The SPI uses the same type of plug but uses coloured dashes to identifiy wires rather than wire numbers. All of the diagrams I have use wire numbers rather than colours & if they do then they don't show the tracer colour.
Can anyone help??

You are aware that injectors on multipoint systems are driven in parallel ?
- and NOT activated in relation to ANY of the engine timings ?
Meaning you can swap the injector connections as you like.
The injector is just a tap which is held open long enough to spray out the required amount of fuel. This is done by pulsing them.

Trying to tell you :
IF you have the 4 injector connections traced down - then find any injector for any ECU injector output [:)]
That's how these creatures have worked ever since the first GTI DELUXE CHROMED ELECTRONIC INJECTION - * <font color="green"><i>multipoint</i></font id="green"> * - system was introduced.
Once you get near these electronic secrets you will find they are not exactly rocket science [8D]
The developments has maninly been on (less ? [}:)]) reliability and cost reductions.

what car is this for?
Ok OK some of you mya have already read this post, ive checked the AX Gti and with taht car it makes no diference what injector goes ware. but the activa has 4 diferent controling pins on the ecu so it really does have multipoint sequential injection. so please dont plug them in randomly befor i have looked up your diagram...
get me the car and engine leters (E.G. K6B) and i can get you another wiring diagram you can look at.

anders- i think ross is talking about the main multiplugs for the injection system in general not just the injectors,there will be other sensors/auctuators to connect.

Sorry, yeh I'm talking about the main connector in the underbonnet fuse box (round screw plug with 11 pins)
The engine is a 1.4 SPI TU3MC L/Z (KDX I believe) & its a '96 ZX
Cheers
