Guys I need help!! please Ka24de Not starting...

[Kustom Kreations]

Ok, I just did a headjob, I had my heads repaired, all the valve seals and gaskets put in new, new headgasket, new intake and exhuast gaskets. by the way this is a s14 ka24de

Everything went back like it came off, now when I try to start it, it puffs once like it ignites but it wont start, the motor turns, it has fuel and it has spark at the coil and at the wires, what else can it be? am I missing something I dont see?

Please help ...

have you tried resetting your timing to TDC? that can be a problem sometimes as to why it won't start. especially when you wanna do all your head work yourself.

this is a timing issue..put youe engine back to TDC (top dead center) on the #1 pistin..check your timing chains and cams for alighnment and your dizzy man..then get back to us.

OK, checked the timing and re did it just to double check, I set the motor at TDC( by setting the motor to the first mark on the pulley) then I removed the distributor and made sure the wheel was pointing to the #1 wire, i tried starting it and nothing no I dont even get the puff, Any suggestions? I check the cams and they are exactly where the were when I removed them, the marks are perfectly lined up. so Im almost outta ideas,

check the tutorials for top dead center tutorial. there are two top dead centers. also, check timing trouble shoot. tutorial link in my signature. or google 240sx tutorial timing etc

i can vouch for the TDC issue. my ka had the same problem, and once it was centered (mine was a distributor problem, but it could be the other TDC) it started up just fine.. I dont know anything about the second TDC though.

[Kustom Kreations]

Ok sorry to be so ignorant, but I am actually learning from you guys!

So now that I know that their is two TDC, how can I tell if is on the compression or the exhuast? would covering the spark plug hoe work even if the cams are off?

I had it where the crankshaft was at the mark and everything else was just like the tutorial says and still didnt start, so should I try the other TDC?

Thanks for all your help and also teaching me about this. I appreciated it!!

Exhaust vs Compression top dead center

The easiest way to know that your top dead center is compression tdc is to observe the postion of the rotor by removing distritbutor cap. It will be pointing close to cylinder one on the compression stroke and close to cylinder 4 on the exhaust stroke. This, of course, only works if you distributor timing is in the normal range. If your timing is really off, you will have to place your hand on the sparkplug hole(sparkplug removed) and feel the pressure build up on the compression stroke as you rotate crankshaft by hand.

alternativelyNote here the position of the cam lobes on #1 cylinder. They are facing outwards which means its at TDC on compression stroke. If the #1 cylinder cams are facing inwards then just rotate your pulley another 360 degrees until they are facing outwards.

This is really kicking my a** and I am in need of some serious help, I've done everything just like the tutorial and all I can get out of the motor is 4 puffs, I've posted some pics to see if you guys see something I dont, please let me know, this pics are taken with the cranshaft at TDC.

First of all, get rid of that damn chain guide and the other one by the distributor hole and throw it in the trash can where it belongs!I'm going to guess that this is a picture of the cams with the engine at number one cylinder tdc.It's hard to tell by the angle of the pictures but the intake and exhaust cams don't look like they are pointing out evenly.They should be pointing out towards the left and the right of the head and slightly up but from the picture, the exhaust cam looks like it's pointed down slightly. In any case, you shouldn't check cam timing by how it looks. You should remove the upper timing cover and set the colored chain links with the dimples in the sprockets like the fsm suggests and remove the chain guides while your at it.Double check your ignition timing and the order you have the plug wires placed on the distributor cap.Also, check that you didn't put the fuel hoses in the wrong way. If you connect the fuel lines to the fuel rail backwards, the engine won't start.I've seen this mistake made more times then I care to count.

It's easy to check for TDC: just insert a wooden dowel rod into the spark plug well of cylinder1. Turn the crank over until you hit the TDC mark on the pulley. The piston will be at the the top of its stroke on compression, so just watch the dowel. If it's not, turn it over 180*.

I highly suggest checking out jim wolff's cam installation guide from their website.

[killbillet]

yeah those cams arent even, i cant tell you which one if not both are wrong but they should be the same, thats something you need to figure out yourself...I would look for a write up somewhere for cam installs like the guy above me said

So yea i just got home from working on my boys Ka we did the timing and when i put everything back together the motor cranked but didnt even do a poof. so took the front cover ov and seen the mark thats going on the lower spracket and then took a look at the old chain and counted that from the lower mark theres suppose to be 6 gaps to the right between the mark and the exhust crankshaft and then a nother 6 between the exhust to the intake. So i was off by one gap on both cams redid that put everything back together and wruum the KA strated with no problem!
