1997 honda crv. wont start

Make sure battery has a full charge. Cranking is starter motor action, meaning the starter motor is cranking the engine. If the starter motor won't crank the engine, then we need to test starter motor wiring circuits.
If it cranks good, but, won't start, have a helper crank it while you check for spark at the spark plugs, where applicable. If spark everywhere, use a gage and check proper fuel pressure and also, check for fuel injector pulse, engine cranking.
Can you check for applicable trouble codes?
I can only make suggestions, you have to do the testing. I give the same info to guys and gals, I don't know how to do it any other way.

Flywheel teeth may be missing ,wire connections at distributor coil or alternator Vacuum leak at intake throttle body make sure all the mounting bolts are tight Hope that Helps

wow Triple posted, do we get 4th?
still no engines size s stated, or if A/T or or M./T tranny. wow.
back up 1 ,2,3, i did answer in depth.
so if 3x ok ,then maybe engine is bad. huh.
if spark timing is way off, the ignored timing belt did slip
5min check with any timing, light, bingo , way off, cam is slipped
and now the valves are all bent and compression is zilch.
short version ,back up for longer.

Check compression and timing belt. If belt is ok and you have compression, check to see if you have a pulse at the injectors. You use a device called a NOID light (basically a light bulb that plugs into the injector plug. Unplug the injectors one by one and plug the light in then crank the engine. Light should blink on and off if the system is working properly. If not check for a bad crank sensor, blown injector fuse and wiring harness. Hope this helps.

Since the engine cranks, the battery, starter motor/starter motor solenoid are most likely
good, so suspect everything else on the list. When you narrow it down, re-post with a
more specific question about that particular component, since 100s of components must operate
nearly perfectly for a vehicle to actually start.

Check all cables to the starter and the ground or negative cable from the battery to the engine or frame. They get old and break down between the insulation and you wont get enough current to start the car

start with the basics, does the fuel pump work, do you have spark, do you have injector signal, are the fuses good, lots of variables here

, pull a plug wire and ground it to the engine body and check for spark. if spark then
check your fuel system pressure, fuel pump
