Now, like I said before when I joined this group, I been working on a 1968 ford thunderbird for a long *** time, when it was upside down crumble up in a cold junk yard (now it all original and complete). All this sudden, I jumped into a 1977 Datsun 280z, I am not too familiar to the straight six motor, and the electrical system, they are really different what I been working on. Have anyone worked on a L28 motor wiring, hoses, and vacuum lines when it all messed up to compete? Is it hard to work on? I wanna hear from the pros.

Thanks.

 

Hard (difficulty) is relative to the person doing the work. What may be easy / hard for you may be hard / easy for me.

What does "all messed up to compete" mean?

 

Yes I have worked on L28's, that have been a mess to deal with. But the straight six L28..is one of the simplest engines, to work on, and or to learn on also. Anyway I don't have to worry about my engine wiring and hoses to be a mess. And to be incomplete. I have 4 280zx's in my yard..lol

 

I mean't like if you ever have a datsun that its wiring setup is really bad, could you able to put it all together easly?

 

I would not be worried about it too if i was some where else, but in USA in California... gee emission laws is really strict, ya gutta make sure every one of them is good so you can pass smog and get her on the road.

 

oh hell yeah, i found that the hardest wiring on the s130 is in the dash and even then its cake, honestly i could even train tonsoffun300zx to do 280zx wiring its that easy and simple.

 

Well, first off... you have a 77 280z? This thread belongs in the 70-78 240z-280z section, not 79-83 280zx section. I'm sure the mods can move it later.

Second, what exactly is wrong w/ the wiring? Datsuns don't have lots of wiring probs unless someone hacked into it.

 

Whoops, my bad, I thought this was the tread that talks about my ride. On my ride it just really diferent, I sut wanted to hear from you guys before I just go right though it.

Like I said, I am new to the site, newbies get confused don't they.

Thanks anyway

 

Tis okay. So what's wrong w/ the wiring?

 

Just my experience:
The POs of my car were nice people, but they probably should never, ever pick up tools again. For the electrical, they'd hacked into the wiring in the steering column, in the center console, the radio, in/around the fuse panels and relays, the windshield wipers, the interior light, the clock, the fule warning light, and the washer fluid pump, plus they'd never done a thing to maintain the EFI harness. For all their "fixing", they never did actually find and solve the problems, which was another reason why I got a good deal on the car.

While I had the car to a bare unibody, I was able to easily clean/repair the obviously wrong parts of the harnesses because I had them out of the car. Took a couple of hours. The remaining stuff that was wrong and had to be tested, diagnosed, and fixed in the car after reassembly took about 10 hours total, and $60 for a new "Accessory Relay" from Nissan (hooray for the guys at Boulder Nissan, which now seems to be a good dealership again). The POs had similarly screwed up all the vacuum lines, most of which were dried out and cracked anyway. I replaced them all and cleaned up the system. Took a Saturday.

Basically, it wasn't too bad on difficulty or time. BUT: this assumes you have a Factory Service Manual and that you're pretty good with a decent multimeter. If you don't have the manual I think it'd be pretty close to impossible to get it perfect. And if you're not good with testing, diagnosing, and multimeter usage, then you're not going to enoy it. So, if you're good on those two counts, dive in! And when it's too confusing, you've always got zdriver for backup help.

happy wiring,
Dave

 

The car just won't get spark any more, since I messed with the coil and swiched in my old ford coil and swich it back. She won't start, she turns and get gas. But no spark, the coil's neg wire is out, I have no idea where this wire go, it seems to be a grond wire. I put it every where on metal around the car. Just won't start. I got the coil tested, the coil is fine, but... I don't see spark coming out of the coil.

 

Thanks Dave,
I now got the idea for how tough the wiring for this car.

 

Do you have any better pics than this one? https://www.zdriver.com/forums/attac...5&d=1208061753

From that it looks like a black vacuum hose.

 

I will get some better photos of what I am talking about tomarrow. It not a vacuum hose, it is the negative wire terminal from the coil. I have no idea where it go, I did downloaded the manual online for my car. it said it go to the ign module, but I have no idea where that is, looked for hours finding it but no luck

 

Hey guys,
I am making a new thread, it callled "where this wire go?". I am making a new one because, you guys don't get messup here. I have high qualtiy photos of my engine and the wires. Thanks
