280z Dizzy firing problem.

Originally had my 280z motor running ok with 260Z Dizzy & 260z Spacer fitted with #1 lead in #1 pstn in dstrbtr cap. Decided that I would fit Elctrnc Unit instead. Cnctd all wires crctly, marked up position for firing order 1,5,3,6 etc & cnctd E12-80 unit (180Deg vrtn) with #1 lead in the #4 pstn in cap as per 260Z markings. Motor fired up but not 100pcnt. Fitted a 280Z dizzy spacer & instld  #1 lead in #1 cap pstn, no joy . Reset dizzy once again with #1 lead in the 4th cap spot & mnged to get car to fire up but not healthy (Back firing thru carbies). Might ad that I used the 260z dizzy clamp plate with the 280Z dizzy. Obviously there is a timing problem but how do I fix it. Got me stuffed #*@!?.Hope someone out there can help.

dude trying to read that was a complete mind f!!k and I'm only 22 , but i think i have the gist of it. i have had a problem very similar to you what you will need to do is get cylinder 1 at top dead centre this can be done by 1) disconnecting the lead from your coil to your dizzy 2) taking the spark plug out and holding your finger over the hole and having someone crank the car but only in little taps it you will have a burst of air come out of it at this point stop 1 cylinder has just fired ( it turns clock ways from memory) from there place the dizzy cap over the dizzy and see where the rotor button is pointing it should be right on or just past a connector on the dizzy cap where the spark plug lead goes in this will be your cylinder one on your dizzy work from there in your firing order going clock wise and presto your problem should be sorted.

We've covered this one before, you need to adjust your oil pump / distributor drive. Grab a manual, pull of the oil pump and set it to factory spec. If you search the forum you'll find all the info here.

Hey mate I know how you feel, we just try to nip it in the bud when anyone starts posting without vowels

May I ask what a dizzy spacer is? I did the 280zx dizzy swap recently but it was just a simple in/out job.

Good luck!

It also makes it easier to search the forum for a topic or subject too.

Here's the thread where we discussed setting the timing right.

Thanks Zman, was not aware of this .Will check with place I bought it from. 

ZMan ,I checked out Dizzy base with wrecker who assures me it is a  Electronic 280z base.

  Hope this doesn't come across as "gibberish" to the LEARNED scribes who obviously have little better to do.  (Sarcasm is the lowest form of wit.) Can we give it a rest & move on fellas. Just want to get my car going so prefer constructive advice, not criticism.

Try retarding your timing say back to 6-8deg.....if your back-firing you may have advanced too far.

(I really had to read your 1st posting a few times over.)

Ahh yes, the Sewing circle of Life is now complete. What if i take some pictures of my setup and put them up here. Would that be better?

Ok I've cleaned up all of the irrelevant posts. They weren't helping anyone.

Let's keep it on topic guys

Many thanks to those that tried to help me with zcar problem. And to those who found it more pressing to

deliberate on less important things, thanks also for their good natured humor. Have been reading Silverz's post & it has all the relevant info (oops) information I require. And also how I should type future posts.
