Re: 1989 honda crx
If you haven't had the distributor out then turn the cam so the rotor points to No.1. Then yiou should see some marks either lining up or close to it.
If you have had the distributor out, set the cam and then worry about the distributor.
Some engines have more than one possible location for the cam gear. I'm not 100% about Hondas so I can't comment either way. Sorry.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

the firing order for your 91 crx should be 1, 3, 4 and 2. You need to identify where the rotor points to when cylinder 1 is at top dead center.
Cylinder number 1 is the one closest to the accessory belts (alternator, power steering , etc, hope this helps.
easiest way to check for a broken timing belt is to look into the oil fill hole on valve cover and have someone crank engine. see if you can see the cam move. if not moving, timing belt is broken. if it is moving it is not broken but still may be off a tooth or more. at that point you will need to remove timing covers and check timing marks. these cars are very simple and you can learn alot by spending 20 bucks on a basic haynes type repair manual.
If you can't get it close to #1 position by turning the distributor you have somethhing off. Double check your timing marks. Manualy turn the engine over 360* and line up your timing marks again. if you don't have a manual , here's a site to go to and download the specific area of the manual that you need. It'll give you timing mark alignment and distributor position. www.pauldesign.ru/honda/shopmanual.html
This is the tricky part... as I mentioned in my solution, When you install the distributor, the shaft will turn because of the gears. You are going to have to pull the distributor just enough so that the gears aren't meshing together and turn the shaft.take notice of which way the shaft turns when you remove the distributor. Once the gears aren't meshing, turn the shaft to the #1 position and go a little past the #1 position in the opposite way that the shaft turned.install the distributor and see where the rotor sits then.if it is still not in the right place, pull it again and go one gear tooth at a time until the rotor lines up with the #1 position. Hope this helps. If you still need more info or clarification, don't hesitate to ask.
Turn crank so that timing mark on front pulley is at 0 degrees.
Remove the timing cover and you should see a mark for the cam to line up with.
You want the cam lobes on No.1 cylinder to be pointing away from the followers wether they be rockers above cam or buckets below. This will be the compression stroke.
Once the cam timing is set you can recheck the distributor. It should point to No.1.
Hi there.... I'm assuming you have the head back on. the easiest way is to try and line up the timing marks an the pulleys and install the timing belt. If you have done this and the timing marks line up as they should, you can take the sparkplug out of the #1 cylinder and manually turn the engine over till you can feel air pressure coming out of the plug hole. continue turning the engine till you can't feel anymore pressure. Don't go too far cause then you'll be on the intake stroke and you'll have to turn the engine the opposite way. with the #1 cylinder at TDC, take you distirbutor and cap and figure out what position the rotor should be at for #1 plug. Mark the distributor somewhere where that position is ( where the #1post on the cap should be). Finally insert the distributor and try to get the rotor as close to that position as possible. remember when you install the distributor, The rotor position will move due to the gear set up. Once you have the distributor istalled, you can adjust the distributor for timing by turning it. Hope this helps you out. If you have any other questions, please don't hesitate to ask..
