The rebuild has finally started today and so far in a few hours I've managed to completely strip the interior.

 

 

 

Next job on my list is to get both the bumpers, tailgate and bonnet off.

 

After that i'll work on the body panels and stripping down the engine.

Looks like my zed has no spark and that's why it wont start.

I think I've tested correctly but to be honest not even sure on that at the moment.

 

After removing a coil-pack along with its associated spark plug i held it against the plenum to check for spark and get nothing.

Tried with a few other coil packs and get no spark from them either.

 

Its a brand new loom so was thinking i've missed something or maybe i've a blown PTU, Relay or fuse.

 

Any diagnostic’s you can run.

That's what I'm trying to figure out. 

Is your ECU known good? 

I'd be tempted to swap in a standard ECU to check spark.

That's what i'm thinking too, although the ECU is a brand new Link G4+.

I'll need to source a donor ecu as i no longer have one i can use.

 

That and check continuity between the ECU side pins for spark and the PTU end - has it run before with the new loom? Unlikely all 6 wires are failed but you never know I guess. You could then check the wires out of the PTU when cranking with the fuel pump relay pulled. Check your coil grounding too. 

Either way - not sure whats available on the Link but a stock ECU might give you easier diagnostics via Datascan/Conzult. Hopefully you can resell it for whatever you pay too.

Good luck mate.

We have spark !

 

 

 

 

 

Locked and Loaded - on the trailer !

Ready for its first official start and mapping session on Tuesday.

 

So for anyone who hasn't seen my facebook posts today my little mapping trip didn't go to plan - again.

However i haven't came away with complete bad news as with the assistance of DynaTune we diagnosed the issue.

It turns out my new loom has permanent voltage going to injector plug 6 which in turn floods that cylinder.

Bummer, as its a brand new loom from wiring specialties.

Good news is we didn't flood it before this was noticed and we now know exactly where to put attention on next to fix the issue.

 

To test the injector harness we used this little glow plug which cam in handy.

Small clip of the first start, prior to figuring out the inject was stuck on.

 

 

 

 

And the rear :

 

 

Also the small test lamp which was real handy.

 

 

Why does shit like this always happen to me.

Wiring Specialties have royally screwed the build of the loom and mixed up the pinout to Injector 6.

 

Tracing it back i get the Injector Socket 6 (Pin 1) going to Pin 115 on the ECU which is for the 'O2 Sensor Ground'

The correct port should be 114 according to the ECU pin guide below.

Getting 12v coming in on pin 115 also scares me as that says it a ground connection.

I have emailed the manufacturer to see what they say but i think the full loom needs to be sent back to be fixed.

Pondering to remove the loom now, but to do that i need to remove part of the dash.

That sucks. Shame the luck you have had.  If you wanted to avoid the delay of sending it all back - you should be able to re-pin the connector to the ECU and switch around any incorrect pins if you have the right pick/tool. You'd probably want to trace and test almost everything though... but might be better than pulling the loom, waiting and then reinstalling. 

Dont need to fully remove the loom, just need to release the pin 115 and swap it over to pin 114 where it should be.

Its just a bad placement of the pin by the manufacturer.

I have taken a few pictures and emailed them about the issue but i'm not paying to send it back over 5mm of space to move a pin.

Think we misunderstood eachother. I thought you were saying you were pondering removing the loom completely.

I was suggesting what you just said.

I was but by the time i replied i had already done what you suggested and fixed the issue.

I heartily recommend Chris@Dynatune, he is very knowledgeable about Zeds, he's got mine running like a wee sweetie 😊

He's a great guy, diagnosed the fault very quickly. 

However had to take it back home to figure out what the issue was by tracing the fault. 

After it was home I managed to trace and fix it. 

Now I just need to book it in with him again. 

She's Alive !

ECU Loom issue now resolved and also managed to tighten the belts.

Still needs properly tuned so not about to go start revving it or anything.

Next date for the diary is the 28th when i take it back up to DynaTune.

 

 

 

Next job to do is get the wideband sensors moved.

As you can see below they are far too low.

 

I'm thinking about moving them into the void between the gearbox and driveshaft.

Near where the hanger is on the below picture :

So another small update on my engine and tuning sessions.

Got the trailer loaded Sunday and headed off to Dyna Tune on Monday morning for a 9am start.

After hooking everything up we were ready for close to 10am

After the initial double checking and tightening of some bolts the first run went great as shown in this video

 

 

At this point all was going great and the engine was smooth and sounding great.
