my 1991 crx will not start.
Car: Honda, CRX, 1991 - Back to Fix-It - Honda CRX Repair Manuals
Q.my 1991 crx will not start. changed; plugs, wires, dist. cap/button, fuel filter/turned the key on and fuel cam out; check engine light comes on and goes off after 2 sec., i hear the click and i can hear the fuel pump turning on. when i turn the key on it wants to start but is cuts off after only a second or two. help?
Answer There may be a couple of things you want to check.
Main relay (underneath driver's side dash)-solder contacts inside break, controls both power to fuel & spark.
Igniter, coil, & distributor (both located inside the distributor housing)-may fail for whatever reason & mechanical & electrical reasons within the distributor.
Ignition switch (electrical portion behind key cylinder)-part fails for whatever reason.
Now I would start with the ignition switch, try wiggling the key while in the ignition & start the car. If the car starts you know that is bad. Next, pulling codes for the check engine light. You can access a 2 wire connector under passenger side kick panel. You will need to jump that & then turn key to ON position. You will need to either count flashes on check engine light or LED from window on ECU (located under carpet front passenger side). Here is a what you will be looking for:

Here is for the igniter & coil:
IGNITER UNIT
Check and service any Honda engine codes before proceeding.
Check the No. 32 50A fuse on 1985-91 models, or the No. 39 50A fuse on 1992-95 models in the dash fuse box before testing.
Remove the distributor cap, rotor and the leak cover.
Disconnect the wires from the igniter.
Turn the ignition switch ON.
Check for voltage between the BLK/YEL wire and ground. If there is no voltage check the BLK/YEL wire and ignition switch.
Check for voltage between the WHT/BLU wire and ground. If there is no voltage check the WHT/BLU wire and the ignition coil.
Check the continuity between the WHT wire and body ground. Service the wire or connectors as needed.
Check for continuity between the BLU wire and body ground. If no continuity check the wire and connectors between the igniter unit and the tachometer or the A/T control unit.
If any tests were not passed, replace the igniter unit.
Turn the ignition OFF.

With ignition switch OFF, remove the distributor cap.
Remove the two screws to disconnect the BLK/YEL front terminal A and WHT/BLU from terminal B of the coil.
Using an ohmmeter, check resistance between terminals. Replace coil if resistance is not within specification.
Resistance will vary slightly with coil temperature. Specifications are at 70F (21C)
Check that the primary winding resistance between terminals A and B is 0.6-0.8 ohms.
Check that the secondary winding resistance between terminals A and the coil tower is 9760-14640 ohms.
If not within specifications, replace the coil.
