ej20g running 2 cyl

[Koom]

Could it be that the coil leads have been swapped between the two cylinders on the one side?

If it's got spark on all four, you could try swapping the leads to the coils, front to rear, on the side that's not firing correctly?

[kamineko]

black or darker plug is always to the rear of the engine for spark and injectors eh?

Yip tried that aswell to rule it out etc. Plugs with the white strip on it to the 2 front cylinders on both the coils and injectors because subarus are racist lol

[rtstk1]

So did the block on the plug test and sparks but a really weak spark. Tested with multi meter and those 2 cylinders only had 2 volts running through them? Is that right? also what voltage are injectors supposed to be at when pulsing?

[rtstk1]

Is anyone in Auckland able to come give me a hand to get it sorted? Not 2 keen on paying a arm and a leg to tow it to a shop aswell as get it sorted.

Hard out my bro doing my head in. Might just have to suckered it up and take it into the shop

Guessing no one else has anymore ideas?

Fuel pump worn out? Disconnect the hose that runs from the fuel filter to the steel fuel line you may have to twist the hose after unscrewing the clamp, i use lilbit of crc helps... grab container hold the hose into the container get get someone to flick the red lights to prime the pump the fuel should come gushing out and speed

so..

plugs....OK

coils....swapped OK

ignitior...have you removed a spark plug, stuck it into the plugged in coil, earthed the base of the spark plug on the engine while cranking, to check for good spark as Rossub suggested? (protip, also unplug injectors on cylinders missing a spark plug or fuel mist will be sprayed around)

assuming no spark from either cylinder,

assuming ignitor is OK because you're using a known good one

-> check wiring from coil to ignitor

-> check wiring from ECU to ignitor

-> check ECU

More suggestions? From what i can tell, you made it to checking the spark plug ? What about the other checks? Where, when and how exactly are you measuring 2 Volts?

Seems to be electrical, and there's no shame admitting you don't have experience in that field. Its going to be less stressful finding someone clued up to look at it

Actually no I replaced spark plugs with new 1s. then removed them with the coil and tried it up against the block like suggested and there was a spark but was very weak. I also swapped coils with the ones from the opposite side to see if there was any change and there wasn't. Still no difference in revs when unplugging while running compared to the other side. I'm obviously not clued up in that side of things which is why I asked if there is anyone in Auckland that could come and have a look. And the 2v was found using a multi meter While coil was unplugged and running

You seem to have miss-interpreted my posts. I've made a list of what you said you tried, with suggestions what to check next. Apart from finding a weak spark, and 2V somewhere It's not clear where you're at.

Nevermind. Anyway. I came across this in my travels and thought of your problem. url]http://clubsub.org.nz/forum/showthread.php?40806-Virtually-no-pulse-feed-from-computer-to-ignitor[/url]

You have checked for CEL codes aye?

Yip have checked for cel codes and no codes. And thanks for the link will have another look tommorow. Sorry if it came off like a bit of an attitude. Just frustrated with it now
