hey

as the topic says ive just relpaced my injectors as a last ditch effort to stop it farting and missing when running on all 6 cyl and then when i unpluged the 4th coil pack in it would run fine (on 5 cyl)... ive replaced the coil packs n swaped pugs around and they are all fine, got a working 2nd hand coil loom and the thing it plugs into and still no luck. so with some advice i got working 2nd hand injectors and swaped them over.

Now i duno what ive done wrong but when i turn it over with the return line off to see if its got fuel running threw nothing comes out?

any help

is the fuel pump still alive?

[R31Nismoid]

^ Agreed.

Sounds like it was a dying fuel pump to start off with - because now it sounds like its totally dead

thanks,

i found it , i had the fuel lines mixed up..... bloody unreal.

its still not running properly when the 4th coil is pluged in.

dunno what to do now. it must be electrical

So it runs on 5 cylinders when #4 coil is unplugged, but doesn't run at all when you plug it back in?

If so, sounds like that coil might be shorting or something?

[slr7000]

they are brand new coils. what could it be shorting on??

it runs but it wont rev and sounds like a lawnmower idling then when u unplug that 4th coilpack plug it runs fine (on 5cyl)

What happens when you swap the #4 coil onto another cylinder?

[cheez]

was this issue something that just happened? sounds similar to wat happened to a mates 33 when we chamged computers, standard for standard, if its a issue that just happened, check that too maybe?

Just make sure your replacement coils are not S2 type with built in ignitor. S1 motor will actually run S2 coils, just very very badly.

when i swap the plugs and coils about its still the 4th one in that wont work,.. i found out last nite that its not getting spark at all.

the new coils i got are s1 unless just jap stuffed my order up but they do look identical as the ones that came out

thanks cheez im sorta hoping it is the ecu to give me an excuse to go Apexi PFC,

i went and seen cp auto electrial this arve cuz we got rained off work and old mate said he'll put a diagnosis tool on her monday and hopefully it will show whats goin on
