How to time a DOHC ZC (D16A8, D16A9)

First remove the crank pulley, belt cover, and valve cover.

The Cam Gears
Look at the valve train and look at the cam towers closest to the cam gears. You will see a hole in the top of each, this hole lines with a hole in the cam itself. With 2 5mm punches, drill bits, or 2 4.5mm allen wrenches. Put them in the holes holding the cams to their tdc posistion, timing will be on 100%.



The Crank Gear
Look at the crank gear, there is a line that is on it that indicates tdc. Now looking at the gear look up and right and you will see an arrow cast into the oil pump. If you line the line on the gear with the arrow you are at almost exactly tdc.


Putting the Belt on
I start at the exhaust cam gear(A) going to the crank gear(B) , then go around the other intake cam gear ,down to the water pump bring both side around on the crank pulley. You may have to adjust the crank gear a little to get it perfect. Tighten the belt tensioner.


put everything back on and you should be on time everytime. I have found this to be the fastest way to get the timing right. The lines on the stock cam gears should have the twuo up arrows obviously up and the two lines on the inner side of the gears should line up even with the head surface

Where "not start" means "cranks but doesn't fire" and may be intermittent, such as only hot days. An easy test is some starting fluid. If it then runs briefly, always suspect the main relay.

You can fix the relay or replace it. If you buy another, still fix the old one.

The hard part is finding it. It is NOT under the CRX's dash. It is directly above the hood release, mounted on the side of the car. Get help from a skilled yoga practitioner. Unbolt & drop the hood latch handle to get up to it.

This link and many others Google will find cover more details.

To fix it, you need good electronic soldering skills and tools. Don't let Joey who pours lead in a body shop near it.
