4age no spark

[NZ_AE86]

First of all the fuel you smell will most likely just be the cold start injector.
The ecu will not fire the injectors unless it sees the confirmation signal from the igniter. The igniter will only return this signal to the ECU if it believes it has fired the coil. This signal has other jobs too but don't worry about that.

I assume you have power at the ECU? Looking into the ECU it is the bottom right terminal and the terminals above and beside it. (Check this on a wiring diagram).
Check the voltage while cranking on these wires and also on the coil positive and the injectors too. It should be 12ish, if it drops below 9.5volts it may still start but something is not right - voltage drop somewhere.
Check the earth voltages at the ECU too, make sure there is no voltage drop.
Make sure you have sufficent fuel pressure.
Make sure your igniter is earthed.
You need a signal to the igniter from the ecu, the igniter sends a signal to the coil and then back to the ecu. You need a scope, good multimeter or LED test light to check these.
If you have all these things it should go!

any luck with this man?

never seen any pics...?? have u posted any up?

whats the role of the igf terminal on 4age ECU

on my diagram its 'igintion conformation signal', is this an input or and output?

not getting any reading out of it from multimeter in any state of igintion/cranking which im guessing is the cause of my problems.

going to try a new ECU, got one on the way that has extact same numbers as the one i currently have

IGT is the signal from the ECU to the igniter to say fire,

IGF is the signal from the Igniter to the ECU to say that it has fired ok.

thanks for that. picks on their way now

wires from igniter

Wires from Coil

Coil and Igniter


Coil, Igniter, dizy


not sure if these help. wiring needs to be tidied up abit[/list]

[l1ttle_d3vil]

don't need that blue plug to get spark.
are you sure that yellow plug on your engine loom is for the ignitor? it should be a green plug for the ignitor (as is on the ignitor) i would've thought. have you got any other plugs hanging loose that you haven't used/don't know what they're for? like a green 2-pin plug or something?

the yellow 4-pin plug on my loom was for a/c or p/s or something like that. something that i didnt need in a ke35 anyway!!

Correct, the green is for the ignitor, as shown in this P I C I cant recall off the top of my head where the yellow one is attached to / goes & I cant run out and check it as car is in Taranaki & I am in Wgtn

[repowered]

im just trying to remember what we did. i think we pinched a yellow plug from the rest of the loom that was unused that had the same pin pattern as the igniter.

cant remeebr if we could find the plug to the ingiter in teh 1st place or not! that doesnt sound right though. all the right wires go back to the right pins on the ECU as i have tested them and the colours are right. e.g: Black / Red stripe and Black / Yellow stripe

[l1ttle_d3vil]

what colour are the wires on your ignitor, from left to right? and are any of the wires goin from the ignitor onto either of the coil terminals?

i've only got two wires going to my ignitor, they are the IGT and IGF signals from the ECU from memory, the rest of the wires are just 12v + or earths. i'll check this stuff out for you though.

how many wires are coming out of that green plug, and how many going into the yellow plug? looks like three from here but from memory they are four pin plugs.

where are all the wires on the yellow plug coming from? igt? igf? and is one of the 12v + or something?

edit - oh and how come you have to pinch a plug from elsewhere on the loom in the first place? did the original ignitor plug not fit the ignitor you had? was your old loom plug a 2-pin plug or something?

[l1ttle_d3vil]

ok ive just checked out exactly how my coil/ignitor are wired up.

i'm using a 4-pin plug for my ignitor as thats what I had available to wire it up with but im actually only using 2 wires on this plug. they are the IGT and IGF signals coming from the ecu. they go straight from the ecu, through the plug and directly into the ignitor. they are (on the ignitor side of the 4 pin plug) a pink wire, and a white wire. check that your IGT and IGF signals are connected to these corresponding wires on your wiring.

my ignitor has the following wires:
pink / white / creme / blank / black.

the first two are the igt/igf signals, the creme one is connected to the + terminal of the coil. im not sure what the next one was but i figured I didnt need it when I was doing some work so removed it. the black one is connected to the - terminal of the coil.

then I have got the standard + and - wires from the original ke wiring/coil going to the appropriate terminals on the coil to provide power to all of this.

hope you can follow all this; check all your wiring and make sure that it is all correct as ive said above. if it isnt, try it this way and see if you get some spark.

as for the voltages of the igt and igf signals, all I can find is that IGT should be between 0.7 - 1.0v while cranking or idling.

Remove the original KE wiring from the coil -ve to try.

[l1ttle_d3vil]

Remove the original KE wiring from the coil -ve to try.

how come?

i know there must have been a plug somewhere for the igniter! im just trying to remember what we did. i'll ask the guy that did it all at work.

umm theres 4 wires going into the ignter and they all go off into the engine loom. internesting that you only have to 2 going to the ignter. i'll try what you said and confirm wire colours tonight.

[l1ttle_d3vil]

yeah, the other two wires on your plug may be the ign + sources or something though, but if its not working that way you may as well wire it up how mine is just to try it anyway.

[repowered]

other 2 wires from igniter go onto the Ballast Resistor. i removed them which didnt make any difference.

also checked cranking voltages across few terminal. i'll have to get what i wrote down later. they were below 9.5v though.

hey

cars at the auto sparky. He wants to know what colours wires on the igniter side of the plug the IGN and IGF wires meet up to?

could someone check on theres?

there white, pink, yellow and black on that igniter plug.

cheers.

[jondee86]

OK... looking in my box of spare wires, and reading the wires from
left to right looking at the end of the igniter :

1. Pink wire = IGT = Blk/Blue wire to 10-pin ECU plug
2. White wire = IGF = Blk/Yellow wire to 18-pin ECU plug
3. Light Brown wire = Common p/s to coil +ve and igniter
4. Yellow wire = Tacho output
5. Black wire = Coil -ve

Hope that helps

cheers for that man!

that sound rite to every one else?

auto electricans got her started today!!!! so stoked!

had to replace fuel pump as it died. hes going to wire it up through ECU & relay so it turns off after 3 seconds on ignition if motor isnt started

[l1ttle_d3vil]

good to hear, sounds good to finally hear it start up aye!!
