Going to start this thread for members to post up what they did each day to there zed. I will start with getting my MOT this morning. So what did you do today on your 300?:cool3:

I kept the car running and moved the connector around to make sure it wasn't a loose connection, applied pressure to the plug to make sure it hadn't lifted off its position etc. No point in removing it to check for green because Lee Dent put plugs on the loom in July and the car has hardly been used since so I know it's not a connection issue. He cut the loom where it had a problem with a break on the loom and rewired a new set of injector harness in.

The injectors he installed along with rail were used ones but good condition and as I said before, the car was running beautifully. It was running great on start up Saturday morning and after driving it less than a mile, it started to run on five.

I had noticed a petrol smell from the exhaust the day before but just assumed it was due to the new exhaust being straight through. If I didn't have to grind the plenum to get access to the screw for injector 6, I may have taken it out and swapped it for a spare I have but saying that, I'm not sure the spare is the same size as it's a red cap.

I'm not in a position to pull the plenum as I don't have a gasket to replace it and would rather give it back to Lee as he has the knowledge that I don't and in my current mood I'm more likely to attack the motor with a pick axe than a spanner..

 

No, I wouldn't dream of pulling the plenum yet. Just perform an Ohm test, this involves putting a meter across the injector and seeing what resistance it has. It may have failed and not open. Also as I've already had loom issues the cable may be broken further back so you must test for a complete circuit. As Pete suggests a noid light is the easiest way to do this.

Well I've spent the day testing and swearing a lot lol..

So far, I've changed coil pack, checked the spark plug, checked and cleaned all connections to cylinder 6. Since slick Petes suggestion about a noid light, I used a 5 smd bulb from the dashboard kit and connected it directly to the injector lead and thankfully I have a good strong pulse.

I have also tested the injectors resistance and although it was wandering a little due to my shovel hands not being able to get the probes of the meter to sit still, I had a reading between 011 and 013 on occasion.

So now I'm wondering.. Could that injector be blocked?

Went to see the Z down the body shop.. all in primer, ready for paint this week finally!! Can't wait

OK, it's official now.. The 300zx known to you all as nostrils has its very own sense of humour.

After spending the last two days under the bonnet trying to fathom out why she dropped a cylinder, I gave up at about 6pm tonight. After everything I tried, I fired her up and yet again, cylinder 6 is down.

My wife knowing how incredibly close I am to beating the car with a bush like John Cleese told me to go and get a beer and chill out for the night.

So I decided to drive it down to the local off licence and get a beer. Gets in, turns the key and (I can almost hear her laughing) all six cylinders fire up.. ???? Wtf???

She drove to the beer shop faultlessly. Half expecting to drop a cylinder again on the way home, but no...

Can someone please give me a little sanity back cos I really just don't understand anymore..

When I got to the second paragraph and read 'i gave up at 6pm' my heart sank...

 

Good to hear it Paul!!!

Proof right there its a silly electrical problem...go forth and find grasshopper:detective:

I'd love to say it's an electrical problem but I'm still absolutely clueless as to what it was.. All the electrical circuits checked out fine so Im thinking it was more likely a blockage in the injector..

It's a mystery but hopefully it's one that'll remain in the past now. I'm thinking maybe the wet and windy weather had made a connection damp or something?? But I guess I'll not know until the next time it happens..

Anyway, she's driving great again so might go for a spin in a bit :biggrin:

Bought some wheels for my DC5 last weekend but before i can get them fitted i thought i'd see how they look on the Zed...

 

 

Ah shucks, accidentally bought another Z...

Yep, and its got a pretty nice interior, though a shame ive just bought another interior off Si :lol:

 

Will be doing the na subframe swap at the same time and hicas delete.

I'm sure there's more than one person who would take the interior off your hands! Good choice

Lets not forget now i have two Zeds to fulfill... it'll probably go in the swb tbh.

What Interior did you buy off si?

What Interior did you buy off si?

This is being done in his group buy.

 

Buy as in commission

So what's the cost on this then? Might be interested if the car doesn't self destruct before then lol

Get a quote from Si for what you want, but I pmd you. The group buy will take place starting September 2017

Just got up and going out to see if my z still has a sense of humour... Taking bets on how many cylinders she's gonna use today.. :lol:

It has been found that they do self fix sometimes Paul.:alien:

Depends how many beers you gave her

Wow, what a surprise... 5 again today then...

Think I'm gonna order a new loom cos it's getting silly now.

Anyone know a good way of testing the coil pack and wiring to it?

these looms can drive you insane...ive stripped back many in the past trying to find faults and you will be amazed how damaged they become inside the perfect looking insulation..wires that have just corroded and broke in half is the norm believe me. Fit a new loom and forget:wink: Its the best money you could spend on these cars as the under bonnet conditions on these cars is pure hell and combined with 20 years plus i dont know how they still run half of them.

Even went down to four at one point but it's looking like the injector plugs are on their last legs.. Gonna buy a full set of injector and coil pack plugs with tails and wire those in, at least then it might run well until I get the money together for a full engine loom..

When it run on 4 I literally touched the plug on cylinder 3 and it sprang back to life.

So that's my next move as it's the only affordable (just) option I have left at the moment..

I think another Group Buy might be in order for some new Wiring Looms Paul. Leave it with me for a day or so:thumbup1:

Paul...I still have the set of coil packs I bought from you....if you wanted them back?
