Rep Power: 0 1995 Civic Starting problems
I have a 95 civic with a 1.5, 5Spd. I have a brand new main relay, good fuel pump, (pump comes on when jumped), good spark, and a good ign switch (already tested), fuses ok (underhood and dash), Have good power and ground to relay main relay only clicks once when key is "ON II" been having too much trouble with this car, had it for about a month and started having an intermittent starting issue which led me to replace the main relay, and now i cant get it to run again, OK while i was typing this the key was on and the relay decided to click and i just started the car, BUT this is not the first time this has happened to me sometimes it starts, sometimes it doesnt, no matter how hot or how cold it is it just happens randomly.
Sorry for the huge write up i am at witts end and need help! any info is greatly appreciated!

If you think a good mechanic is expensive, try hiring a bad one

See if you can find someone with a good ECM to try in it. Just a hunch.

ive checked the wires before, but today i happened to open up the dist. and pulled the rotor off and it came on, could be i moved something or just the car deciding to work again?

Re: 1995 Civic Starting problems
Why did you have the key on while messing with the distributor? Good way to get zapped.
Found a good PCM to try yet?

yea good way to get zapped Haha im so frustrated that i didnt even think about it but ive been zapped by a dist. before..... but all day throughout the day i went outside and tried 4-5 different times and the relay would click on, and fire the fuel pump after about a 5-10 second delay and the car would start and run, until just a minute ago i tried again and the fuel pump would not come on even after waiting a few minutes with the key on. Still bumfuzzled. Still havent found anyone with the same generation pcm/ecu

Open up the ECU, got any leaking capacitors?
Just an example, they don't have to be leaking that bad to be a problem.
Quick google came up with several items about bad ECM/ECUs.
Here's one

Re: 1995 Civic Starting problems
Make sure that all power is going to all electrical system.
Have you ever checked the output signals from starer motor?
If it doesn't get enough voltage ,starter motor will not work( if there is no problem on starter motor you can just hear clicking sound without cranking.)
I am not sure that your civic has those sensors.. you need to check..
MAP,MAF, CKP , IAT or Idling sensor.
If one of those sensor does not work, it can also effect on your stating problem.
If you have DMM or lab scope, then you need to back probe each sensors then see the result or signal waves.
You can see the values or signal waves for each sensors on google.
Or i guess you can find those result on out forum
