CAR WON'T START

1997 Honda Civic

Electrical problem
1997 Honda Civic 4 cyl Two Wheel Drive Manual 180000 miles

Hey,
I've got a 1997 Civic ex with 180,000 miles on it and the other day it stalled at a red light. I thought it was just my clumsy foot on the clutch. Then it wouldn't start back up. My friend and I pushed it back to his apartment. Now, it's two weeks later and the car still won't start. I know it's not the battery or alternator because I still have functioning lights, radio, fans, ect. When I turn the key to the on position, I also hear the fuel pump pressurizing. (Or something like that. I don't know the technical term for it.) My friend and I also pulled the wires and plugs, one at a time, to see if it was getting spark. All the plugs failed as well as the wires. I've heard that it could be the distributor cap or rotor. I've also heard that it could be my plugs or wires. Also i've heard that it could be something as complex as a timing belt. I didn't hear a loud clink noise like would be expected for when it breaks. I'm really on a tight budget and need to get my car back on the road without towing it to a mechanic or having someone diagnose it. That costs quite a bit of money. Any help you have would be greatly appreciated. I would like to diagnose and fix it myself. Thank you!

After getting the new module, we put everything back together and tried to start the car with no luck. We removed a spark plug and tested for spark, none at all. just to be sure, we cleaned the plugs and checked for spark on every plug... nothing. I tested all of the connections inside the distributor. All connections on the ignition module read 12v as do the terminals on the coil. There is another part that i do not know how to test, it looks to be a pick-up module. I am not sure if this could be the problem, how to test it or replace it. I will include a picture, it is the piece in the upper left hand corner of the distributor.

There are 2 distributors listed for this EX model the pic i sent earlier must be the right one the other looks totaly different ? .. so the CKP/TDC/CYP sensor is in the top left corner of your photo ..(ckp = crank position sensor.. tdc = top dead centre sensor cyp =cylinder position sensor and they are all in the one unit .. here is how to test ..

Turn ignition off. Disconnect CKP/TDC/CYP sensor distributor 10-pin connector. Measure resistance between CKP/TDC/CYP sensor terminals. See CHECKING CKP/TDC/CYP SENSOR RESISTANCE . If resistance between sensor connector terminals is 350-700 ohms, go to next step. If resistance is not as specified, replace distributor ignition housing. See Fig. 8 .
Check for continuity between ground and each specified CKP/TDC/CYP sensor terminal. See CHECKING CKP/TDC/CYP SENSOR RESISTANCE . See Fig. 8 . If continuity does not exist, go to next step. If continuity exists, replace distributor ignition housing.
Reconnect CKP/TDC/CYP sensor distributor 10-pin connector. Disconnect PCM 31-pin connector "C". See Fig. 3 . Measure resistance between specified PCM connector terminals. See CHECKING CKP/TDC/CYP SENSOR RESISTANCE . If resistance between sensor connector terminals is 350-700 ohms, go to next step. If resistance is as specified, go to next step. If resistance is not as specified, repair open in suspect circuit. See the WIRING DIAGRAMS article. See Fig. 3 .
Check for continuity between ground and PCM 31-pin connector "C" terminals C2, C3 and C4 individually. See Fig. 3 . If continuity exists, repair short in suspect circuit. If continuity does not exist, substitute a known-good PCM and recheck. If symptom or indication goes away, replace original PCM. (powertrain control module)

CHECKING CKP/TDC/CYP SENSOR RESISTANCE

CKP terminals 2 & 6 pcm number terminal C2 & C12
TDC 3 & 7 C3 & C13
CYP 4 & 8 C4 & C14

Just tested terminals and they all read 370 ohms.

I seem to be having similar problems. Can either of you tell me if this worked or where you went from there? Thanks.
