It was aftermarket, And like I said, didn't seemed to be hooked to anything.

And I agree, I'll tell him when he gets back. Great another engine pull. Oh well Its not nearly as hard the second time.

Well thank you very much for the help!

 

If you have small enough hands, you don't need to pull the engine for a harness swap.

But let this be a lesson as to why every Z32 owner who's had an engine pull has also replaced the harness.

 

Actually what I learned was, use the right parts for the right engine! But I already knew that. But who ever decided to put a TT engine in this Z and still use the N/A one really needs to figure that out...

 

Thread resurrection.

Would a bad ECU Prime the fuel pump and fire the injectors but not send a signal to the PTU to fire the spark plugs?
Also how do you test an ECU?

 

still no spark?

 

Yes Still no spark. I still haven't changed the EFI harness on that Z tho. He doesn't believe me that the EFI harness can go bad like that. I told him with the engine bouncing off the firewall with no transmission when he towed it home is probably why it went bad.

 

It started just now!
I got out my trusty volt meter and went to town.
Ptu had power and ground
ECU power and ground
Coils, no power but had ground and single from PTU

So I followed it to the relay, Relay has power and signal, and relay tested fine. nut the single side of the relay has no ground! as soon as I just jumped that relay with a peice of wire it fired right up!.

now Wheres the ground for those relays??? in the engine bay btw

 

good job!

 

I'm not sure where those particular relays are grounded, but it clearly doesn't make a difference... just pick a nearby chassis ground and run your own wire.

And 2nd on good work.

 

Thanks! Tho I feel a little stupid for not checking that before.

Isnt it a little strange that entire relay box doesnt have a ground anymore? well I think most of them anyways... er I'll look into that and just ground it for now.

How the hell do you bleed the clutch system in a Z32 when all the lines are totally dry? Seriously. I tried the normal way and got nothing.

 

crack the top bleeder, crack the bottom one, then fill up the reservoir, and shut the bottom bleeder when it starts dripping steady. then finish bleeding from the top.

 

I've never ran it dry, but this is exactly how I'd try to do it. And just as he said, I always do the bleeding procedure from the top bleed point.

 

Crap. I hope the line isn't plugged cuz thats pretty much what I did...

 

you've got to back off the bottom one a lot. that's been my experience with the slaves i get for $19 at advance auto. the bleeder is almost coming out by the time it flows.

 

It might take a while for the fluid to make its way around... I set up the clutch on my S30 a couple months ago and it was bone dry (sat for 2 decades) and took quite a few pumps of the pedal before the fluid reached the slave cylinder.

 

Ok I'll do that. if all else fails I'll just go get a vacuum pump. lol

Ok lets see... Bleed the clutch, fix the half million electrical BS bugs, Fix the Power steering and it should be good to go! Oh and install the exhaust lol

If winter didnt come rolling around in the 20F for like 3 straight months I would have had this damned thing fixed.

OH before I forget again! Can anyone give me an N/A wiring diagram and a TT's vacuum diagram? The FSM was useless for that as it was corrupted...

 

remember to use ATF in the ps reservoir. if there's a problem with the pump, it's pretty easy to take apart for some repairs or cleaning or if nothing else a verification of your problem.

 

OH thats not the problem. theres a big leak somewhere as it pours out just about as fast as I put it in... but all the lines are hooked up and tight so I'm hoping I just missed a hose clamp or something somewhere.

 

The high pressure hose is a common fault on the Z32... known to leak with age.

 

where do you recommend getting one from?

 

The high pressure hose? Any certified Nissan parts vendor. Kyle at ImportPartsPro.com, Greg at SpecialtyZ.com can probably get them, Coz or Ultimate Z (if you want to go that route), Courtesy Nissan (when it comes to OEM parts, they're fine), local Nissan dealership, etc.

 

ok. someone's write up for changing it on tt.net mentioned getting it from advanced for a good price so i was really wondering if you found that cheaper option acceptable, but i guess i didn't really need to ask

 

Publicly, I don't generally condone cutting corners on the Z32... but I've used parts from AutoZone with good success, before. Not the high pressure hose, though... considering the difficulty in replacing it, I'd probably go with OEM on that one. As a rule of thumb for myself, if it'd be a bitch to replace a second time, I don't cut any corners.

 

wow. autozone has it for about 25% of the price that courtesy does, unless they have their descriptions mixed up.

 

AutoZone.com doesn't list any pre-formed PS hoses for the Z32, from what I see. It's all universal fit "pick the right size and cut it" stuff... and given we have banjo fittings, that's not a good option.
