First I'd better charge the battery

Thanks for the assistance guys. I've checked timing, dizzy, plugs, leads, fuel filter and am almost ready to change the dizzy out. Haven't done much to the carbies, which were never setup correctly since they were installed and I'm not too familiar with them (been working on fuel injected cars too much). So I'll have a play around and do some reading to see what adjustments I can make.

It's been a while since I've posted here about my engine problems, as I haven't had much time to troubleshoot. When I attempt to turn the engine over, it turns and fires but doesn't start. Then it seems to blow off from the Carbies, with a puff of smoke and the engine stops. Sounds like a gush of air coming out. Any suggestions on where I should start?

I'd just like to distance myself from these photos. These are taken by the previous owner, I claim no liability for its content . Apparently they belong to his girlfriend. In all seriousness I am trying to sell this body kit. I'm not too sure how much it's worth so make an offer and you might be in with a chance.

Hi guys This fibreglass body kit is one of a kind, built for a 260z 2+2. Includes Front, rear bumpers and side skirts. It's in Excellent condition, with only a minor crack in the rear bumper. I'm ultimately looking to swap this for both front and rear bumper (including mounts and indicator panels). Negotiable on price depending on the condition of the bumpers. Also comes with 2 fog lights and a small can of touch up paint. Price is negotiable, over $800. I'm located in Melbourne. Best to contact me via PM or email as I'm currently on night shift.

Thanks heaps for the help so far guys, you've been great. I managed to find top dead center by taking out the number one spark plug, with a torch and a 27mm spanner However the engine seems to be intermittently miss firing, while sitting at the same idle speed and same timing. I'm going to do some more things (tune it properly, replace points etc.) and see how things go. Thanks again

Ok, finally fixed it. The Dizzie for some reason had moved all the way forwards putting the timing COMPLETELY out of whack. Moved it back a bit and it starts Quick question, I want to get the timing right but there's no marker on the crankshaft. I'll mark it myself, do I mark the crankshaft at 0, when the engine is at Top Dead Centre? From memory I find TDC by taking spark plug out of number 1 cylinder and putting a screw driver down to feel the piston come up. If I can feel compression while cranking the engine, then it's the firing phase not the exhaust phase. and when piston is all the way up, i'll mark the crankshaft pulley at 0? Does this sound correct to anyone?

OK, now it's not running fine. It's not even starting any more. I checked all the other spark plugs by replacing them wtih the old ones and still no go.

Found the root cause of the issue. Backfiring and stuff is due to Carbies not being in tune (obviously) but the main issue was a faulty spark plug (which was brand new). pulled the spark plug leads off each cylinder to see which one wasn't firing. Discovered number 5 wasnt' working. Chucked the old spark plug in and it worked a charm

I pulled the fuel hoses off from tank to filter, filter to pump then pump to undercarriage metal hose and all are clear. What would I need to check in the carbies?

Ok so I replaced the fuel filter and it runs a little better now... not backfiring as much, but still can't get the revs up. It starts, but stalls if I take my foot off the gas. Then after keeping my foot on the gas for 30sec it kicks, with smoke coming out of the carbies, and dies. Points look OK, and ignition coil is giving enough juice. The battery is pretty dead, but once it starts the Alternator should kick in ?? Alternator is fine. To me it sounds like the fuel lines are clogged to some degree... Any other ideas?

It was running fine before I put it on the trailor and bought it home, so I suspect it's fuel related. The tank doesn't have a cap on it. I'm going to have to drain the fuel to change the filter, i'll take a look and decide if I need to flush the tank. Thanks for the posts guys

I'm going to replace the fuel filter tomorrow. I have a timing light but the engine won't run enough for me to time it. Might get the girlfriend to sit behind the wheel while i'm doing it

Hi All Bought a 260z recently from a friend of mine. Has a 280z motor in it, with dual SUs. Problem when I got it was it wouldn't start. Thought it was out of fuel so I put about 4L in and just a little bit in the carbies to get it started, as well as replacing the spark plugs. Now it starts, but backfires, with white smoke coming out of the carbies, then stalls. Engine also won't rev higher than idle no matter how much you put your foot down.

Hi All Thought I'd introduce myself. I'm diving in over my head and buying a 260z from a friend of mine. I've always been a big fan of coupe's and I loved the look of this car so I just had to have it. I'm planning to spend the next 6-8months fixing up the car as it's in bits at the moment. had a good look at these forums and looks like a great bunch of people who know what they're talking about. My knowledge of cars is alright, i've done bits and pieces here and there but I'm sure I'll learn a lot fixing this one up. This car has had the engine recently re-built. New paint job and a body kit fitted. Custom front made and fitted. Comes with rebuilt Hitachi's with SUs fitted. New clutch and no rust, so I figure it's a good starting point. Cheers nemski
