New toy WILL play :-D

[grinder]

you can just come to mine and have a listen if you really want !! LOL

if you can find the earths then i would LOVE to know where they are

actaully you can test something for me if you want - there are two realays at the front ( near the washer bottle - unplug them and see what happens )

one should stop the headlights working - the other is the dimmer relay and should stop the dash lights working - thing is i dont know which one is which

That explains you not waving back then :driving :WaveBye :Hammer :rollin

It looked just like you though, right down to the fag in the gob :Laugh :bandit

Oh well nevermind :wiggle

[Mobilemick]

I got 4 relays behind the front grill,  will look for the ones near the washer bottle,

Next time im up chorley,  i`ll call in,  (i`ll ring first)

[Brett]

It looked just like you though, right down to the fag in the gob :Laugh :bandit

 I presume you mean cigarette?:Laugh Or is there something oyu\'re not telling us grinder? :rollin

 I\'m sure we will get the bugger running this w/end mate

[Mobilemick]

Fag, Bugger,  wtf   lol

[Grizzly]

Stu, I was just thinking, If you got a Multi meter with a Long neg wire can\'t you hook it up to the Battery (so its a reay good conection) then set it to Ohms and go around Touching things like ECU, Body shell, Engine etc and see if you get more Resistance in things (will tell you how good the earths are).

I still think you need to do a Bit more messing with the ECU before you write it off as not the Problem. I\'d still be very tempted to swap the ECU\'s over (Coupe on the Vert and try then Vert on the Coupe and try) they don\'t have to be bolted in properly just make sure they are well Grounded. Quick way of finding out for sure though...

Did you ever get a Fault code off it?

[FLAT4MATT]

Yes i meant cigarette, wasn\'t implying that stu dabbles in any funny business :spank :Ladys-man :spank




Sorry couldn\'t resist....


This smilie does NOT GET USED ENOUGH


:spank :spank :spank :spank :spank


:Laugh

Anyway where were we, swapping ECU\'s and checking earthing points, ahem...

[grinder]

hiya chaps

had ANOTHER look last night

i know what you mean about the resistance in the wires - thing is - they are all coming out good - so that poses a problem

found 2 earths so far - one by the trailing coil and one neear the drivers head light - these have been cleaned up and put back on

still no difference

so then we ran a set of jump leads from the NEG terminal to these earths - still no difference - so we tried various places around the engine - still no difference

we then disconnect the AFM ( removal of airbox ) , the BAV valve plug , the AC plug and the fuel pump and resistor ( under air box ) and the injectors are STILL firing - and we have now found out that the primaries and secondaries are both firing

we are NOT ruling out the ECU - this will be swapped and tested - at least we can rule out a big chunk then

any more ideas are welcomed

Stu

Mick - those are the relays im talking about the 4 - should be headlights , dimmer , AC and something else

Stu,

If the Injectors are firing BEFORE you crank the engine this is bad !! :eek

There should be no injector action until the engine is cranked / running.

This might be a wiring fault on the injector harness itself - it\'s possibly shorted out to ground somewhere, or getting a negative going signal that\'s pulsing.  The left most plug on the ECU (as the connectors face you) carries the injector signals - if you unplug that and it stops - then it kind of points the finger at the ECU - that\'s not 100%, as the pulsing signal that might be shorting the injectors may also be coming from the ECU.

Have you tried taking a negative feed straight from the battery -ve terminal to the black wire with the eye washer on it that provides the ECU earth signal ?

Next question would then be what ECU have you got in there at the moment ?  The N380 with knightsports chip, or your original N374 ?

[grinder]

thats right prof - they are firing before it is cranked - hence the amazing amount of fuel its getting !! LOL

its currently got the N380 ecu in it with the KS chip

really need to get the one out the coupe just to remove the ecu from the equation

we have tried a feed from the ECU earth to the battery - and still this doesnt help - although i can test this again when im messing with the ecu ( im sure we have tried this just not 100% sure !! LOL )

i need to make a complete list of what has been tested and what hasnt

stu

[Mobilemick]

thats right prof - they are firing before it is cranked

u sure stu ?
How are u testing them to see if they are firing,

Mick

[grinder]

OK im not 100% sure - but if you get your hand to them - you can feel "something " pulsing or firing

and "idiot hat on" how can that much fuel get into the engine if the injectors arent firing ??

Stu

[FD3SNuttah]

dude check the crank angle sensor that is what fires the injectors.

[Mobilemick]

Crank angle sensor SHOULD only work, if engine is cranking,

thought the relay for the headlights Stu,  its the one closest to the drivers headlight,   and i wrote the pin out down for u to check,

Mick

[grinder]

the CAS has been checked and OHM\'s out OK - although it could be a bad earth - need to check this AGAIN !!

found me a N374 ecu aswell - only down side - its in aus !! LOL
