I recently purchased a replacement timming chani kit for my 93 nissan pu 2.4l 4cl 12 valve 2wd ka24e engine. the kit contained both main and cam sprockets, chain, left and rght guides and tensioner and all seals for fromt cover. The main cam sprocket was ok after instalation stayed at tdc bur per the haynes manual the cam sprocket timing mark was to be on the right side 3:00 and the dowel slot was suposed to be at 12:00. It also stated to not turn cam because the valves would hit the piston crowns. Now engine turns but will not start. It is completely assembled. Does the Cam sproket have to be set where they said?

it doesnt sound like you had engine in corect position. take cover back off where you can see the timming marks and spin over 2 full turns. #1 may have been up but not on firing stroke.

all should line up exactly as the manuel says.

If I place the crank pulley on the timming mark at TDC would I just be able to remove the valve cover remove the timming chain from the cam shaft sprocket and turn the camshaft sprocket untill the timming mark and dowell slot are at the position indicated in the Haynes manual of the dowell pin at the 12:00 position and sprocket timing mark at the 3:00 position? The roter was pointing at the #1 spark plug position.

Suggested Repair

Remove the front cover so the timing marks are visible, rotate the engine two full turns, and confirm every mark lines up exactly as the manual specifies. The No. 1 piston may have been at TDC but not on the firing stroke.

Conversation Summary

The owner of a 1993 Nissan pickup with a 2.4L KA24E replaced the timing chain kit, but the engine cranks and will not start. The cam sprocket mark and dowel did not match the Haynes positions of 3:00 and 12:00. The expert said the engine was likely not in the correct position, advised removing the cover to view the marks, turning the engine two full revolutions, and aligning all marks exactly as the manual shows, noting No. 1 may have been up but not on the firing stroke. The owner then asked whether the crank could be set at TDC and the cam sprocket repositioned after removing the chain; that follow-up was not answered.
