ok so i swapped a ka24de into my 90 and it won't start, i got fuel, spark and compression, it's gotta be the timing, i know where the marks are on the crank pulley but how are the marks on the cams suppose to line up when it's at TDC on the compression stroke? yes i've searched and didn't find anything
thanks

and check the CAS. pull it out line it up and re-stab it.

XXX4life · 10-19-2004, 10:19 PM

yeah i hear the injectors and i'm an idiot but what is CAS?

vegita319 · 10-19-2004, 11:03 PM

heh, if i'm correct, CAS is the Crank Angle Sensor. On the KA you would rotate the distributor towards the rear of the car to retard timing and towards the front of the car to advance timing. If the car kinda starts and missing still. You have to take out the distributor and advance it by a teeth or so. This should allow you to get the correct timing and allow your car to fire. If your car is not firing at all, you might be on the wrong stroke and have to rotate the distributor 180 degrees. For example, if you were at TDC and when u take off the cap the rotor was located on coil number 4, rotate and align it with coil number 1. That should rotate 180 degrees if you were firing on the wrong stroke of the car. Again, adjust the timing accordingly. I hope that helps.

I didnt' answer your question. To set it the pulley at TDC, make sure the the alignment pin is directly above the yellow mark of the pulley (I think its the second one from the left) if your yellow mark faded like mine did. You can go to here for pictures: http://www.240sx.org/faq/articles/timing101.htm . For a Factory Service manual of the cam alignment go here: http://www.zeroyon.com/TheSite/techservice.html . Hope that helps.

i understand where the TDC mark is on the crank pulley but i wanna know abotu the cams? i set the pulley to TDC and had the valve cover off so i could see them cams lobes on number 1 were all facing out so all the valves were closed and a set the distributor to #1 and it didn't start, what couldi be doing wrong?

XXX4life · 10-19-2004, 11:38 PM

i finally got it started, it's not perfect, it's running like crap but atleast i know the timing is closer now
