Ok so maybe you guys can help me out with this nightmare lol.
I've been searching for about 2 weeks now.

So car is a '90 hatch with a '93 engine/trans & ECU. When I first got the motor in I never bothered to open up the valve cover and check the cam timing. I figured it would be ok. But it apparently wasn't. Exhaust side was way off and when I hit the starter I was taking out valves . Afterwards re-timed it and did a compression test, wasn't too good.

Cyl 1 - 115psi, Cyl 2 - 50psi, Cyl 3 - 90psi & Cyl - 110psi. Not good so I bought another head which came from a 95. While I was at it I replaced the piston rings and rod bearings and bought a cometic headgasket and arp head studs. Compression is now between 150-160psi. Plan on building up the original head to replace the '95 later on.

Now that everything is better and all back together I can't seem to get it to start. I confirmed spark by cranking with a plug on top of the valve cover. Spark was yellowish however but the plug was old. I know I'm getting fuel because I can smell it when I crank and smell from the exhaust. Set ignition timing time and time again and its right on the money I believe. When its in and set at tdc the rotor is pointing perfectly at plug #1. And yes I made sure I set it one compression stroke. Its a little hard cause I have to tap it in there with a mallet.

I checked the ecu for codes and I'm getting a code 11 (cas) & code 34 (knock sensor). I'm not sure if it would throw a code 11 just if the timing was off or not. I haven't been able to try another one. Also the PO had simplified the intake manifold a lot. There are only say 4 vacuum lines left.

I know it was a little long but didn't want to leave any info out.


Thanks in advance.

check your knock sensor. if its bad itll give you that problem your having. let me know how it goes

It'll keep it from starting?

It'll crank over but it won't start. Also check your main wire for ur coil pack off the distributer

Ok so I was so close. It was at the point where it would run for a few seconds or so , so I'm guessing the timing was off but my damn dizzy basically broke in half lol. So I need to get a new one now.

uh if ur dizzy doesnt slide in easy then the idler gear bolt hole maybe ben or the bolt it self
on the ka its supposed to slide in smoothly..lol
and when u set dizzy it has to point behind 1 when u slide it in then it rests at 1
if u understand that

Yeah when I set it. Set the idler a little back so when it goes in its at 1. I'll definitely be doing that when I get another one.

Here is a nice guide if you need it: 240sx Distributor Timing

If your engine doesn't run after you get the dizzy maybe look at your fuel lines, that was my problem: I could crank my engine and it would have random combustion every now and again.

Here is a picture of correct fuel lines: Ka24de by vaioalii on Photobucket

hope this helps somewhat,
