NEED HELP!!!!

[240tst]

hey guys i have 93 240sx hatchback and i just finished doing a ka24de swap....the motor was in my friends car and was running fine when we took it out....

-after i put the motor in an connected everything the car did not want to start....
-i checked all the connections and wires and hoses....everything seems fine
-at first the car would turn on and idle at 2 rpms...then go up to 3rpms or so and then shut off
-so i rechecked everything and swapped the ecu....(thought it might help)
-then the car turned on and it would go up past 2 rpms and then drop to under 1 rpm...maybe 7/8 and it would just iddle there....
-HOWEVER...it would idle very ruff and the the motor was shaking like crazy....
-so alot of people told me to check the timing....so i did....
-aligned it top dead center...by removing the first sparkplug...with a screwdriver in the chamber//also based on the timing marks on the pulley...set at the 3rd mark counting clockwise (have 6)//and by checking the first cam lobe...it was pointing to the side....
-then took out the distributer and realigned it so that it was at the first spark....and i tripple checked that it was right in the middle

so then when i went to start again....nothing....the motor just cranks....fuel pump working fine cuz i can hear it turn on and im getting fuel cuz every once in a while it will backfire....changed the sparkplug wires and the spark plugs are good....

SO WHAT CAN IT BE????

im really lost and dont know what else can be wrong....i need some guidence

any help will be appreciated.,,....

Did you set timing on exhaust stroke? Turn the motor 360° and retime.

[240tst]

I don't think so because it retimed it atleast 3 times today and I had someone guide me who knows about motor and stuff so I made sure it was right....I dont think timing could be a problem

[Pro ViZion]

Are you getting spark? And are all the plug wires in the correct cylinders?

[S13_RB25]

Check for spark at the plugs abd if its there then its your timing. Also TDC is second mark from the left not 3rd. And the stock ka timing is 20 BTDC, which is the last mark on the right. So after you get your motor TDC, rotate it back to the last mark on the right and set your dizzy to spark plug #1... Go from there and adjust the timing with a timing light.

[240tst]

Ok but I have an s14 dual cam ka...and there are 6 marks...so I should still put it on the last mark

[compactfean]

Your trying to tell me you timed this thing 20 times and dont even know which mark to time it off of? I guess we all know know everything until we have to pay a mechanic to say its the f*** timing! Go get a chilton book.

[S13_RB25]

Yea the timing on all ka24de's is on the same marks. TDC 2nd mark from the left and stock ka 20 BTDC timing is the last mark on the right....

[240tst]

Ok so this is what I'm gonna do in the morning...
- take ou the distributed cap and rotor
-take the 1st sparkplug out and crank he motor while coverin the hole...when feel compression that will mean I'm on the intake stroke
- then make sure I'm tdc by aligning the crank wheel to the second mark
- then slide the distributed cap and rotor back in while at the 1st spark

And that should do it right.... And if I need to fine tune it then rotate the distributed cap

[compactfean]

Yeah that should do it but actually its compression stroke not intake. Also you need to line up the dot with the groove on the dizzy. When you stab the dizzy. If you are not sure if its right then crank the motor to. 20° BTDC. And see if the rotor is pointed right at cylinder #1.

[240tst]

Wait what dot... Your talking about the grove that touches cap right...but what dot
...

I'm going to the car now(it's at a friends house) so I'll check to see what your talking about

K..I think I made some progress because now it turns on and idles somewhat ok but really ruff... The engine shakes...alot...but when i give it guess it sounds fine...at least I think so....

Btw.... I'm only running straights headers and pipe to cat....the cat is off and I'm making a custom exhaust so I'm waiting to getting it welded....so it's really loud....and also that pipe by the firewall that comes out of the headers(stock) I cut it off and its not plugged right now....could this causE it to shake like that???

I tried adjusting the iacv but At first I did it clockwise so the idle got lower to about 500 then I then went counterclockwise and it went up a little...

I took a video so please check it out...let me know if I did something wrong or what else I need to do....

This is the video...someone please check it out and let me know what's wrong....I know I'm close to getting it running perfect ...needs this baby on he road asap

[compactfean]

its not firing on all 4 at times. Very healthy misfire. I'd start with cap rotor plugs and wires. If you can't afford everything take a spray bottle with water and spray around wires cap and coil to see where its arking. At.

[240tst]

Is very healthy a good thing or a bad thing....and if I change all those parts everything should be good???

[youngun21a]

TDC

dissy on the
distributed
just line it up like it show on the pic with the round dot once it's in and tdc,,it should fire right up with no problems..

[240tst]

Ok the mark your talking about it on the rotor right....cuz that's what it looks like on your pick...

So crank the motor to tdc and then align that mark to first spark and start it up???

That's it??? Or am I missin something

[compactfean]

Thank you young gun! That pic is what I was trying to discribe. The picture of the dizzy gear shows the two dots on the gear side and the notch on the shaft. If you line up the dot on the right to the groove. And then stab it when engine is at tdc that is how its done. The rotor will not be pointing to cylinder number one yet because in order for the rotor to point to that part in the cap it would have to be at 20° BTDC. I think you have it stabbed right because it actually starts but the only way to be sure is to check timing with a light. I think you've got bad cap or wires.

[youngun21a]

yup just the way is in the pic.. line up the dot once u insert it will rotate and be perfect aline to cyclinder one..once u insert the dizzy u should not have trouble, it will go in with no effort...and if u insert and it taps the gears it's not tdc rotate a little and it should go in..once done it should turn on the first try..

[240tst]

Ok I looked online and saw the notch and two little dots that you have up there...but when I align it I align the first dot or second one??? And so after I put in the dizzy back in at tdc then crank the motor to 20btdc and it should be at 1st spark correct????

[compactfean]

@the second dot (upper right) and yes that's correct.

[240tst]

K...thanks alot...I will try this hopefully today and let you know what happens

[compactfean]

Dont forget your spray bottle

[240tst]

How exactly will I do that btw...what is it supposed to do or what should I look for

[compactfean]

When you spray a mist it allows your Ignition failure to visibly Ark. I usually do it in a dark garage so you can see what's arking. I've seen everything from bad wires to bad caps and cracked dizzy by doing this which I couldn't find The problem Without humidity. I learned this trick from a European Guy that I guess would have cars come in when it rained for misfire issues but when it didfnt rain there where no problems. So ever since I keep a spray bottle in my tool cart. I used to running a screw driver and run it between wires and cap and what not but like using a spray bottle so I don't get zapped! Pretty much it helps find where the electricity is going. Like if a wire is arking to the block instead of going through the spark plug causing the spark plug to not fire.

[240tst]

K...just did the whole aligning of the dizzy thing...did it twice...and still misfiring...changed the cap and wires are new...and the same...idles where it's supposed to but not the right way...still shaking...timing seems good actually better now because if I move the cap in any direction the it messes up

[compactfean]

Ohm out the coil to see if its good. And what maf are you using? You need to use a dohc maf and not the sohc maf.

[240tst]

Ok well I need to get a volt meter for that...but I'm using a n60 maf...it was running in a friends 240 stock rebuilt ka dohc

[compactfean]

Thats your problem then. He rather had a chipped ecu for that maf or was using an safc. The car will not run right without some sort of tune on that maf. Unplug the maf and start the car. It should idle perfect and only rev to 2500rpm
