Okay so I have a 94 civic ex with a d15b7, I think. It was running just great until last night when I went to leave the house; it started up like it usually does and then suddenly shut off? I then waited to this morning to start my diagnoses. I found that the car IS getting spark and fuel to the rail. When I turn my ignition on my check engine light comes on and then turns off; just like it should, I can also hear the fuel pump prime followed by the click of the main relay. All sounds good so far.. I also pulled the upper timing cover off to inspect the timing belt; it appears to still be tight and in good working order.

I guess my next test will be to remove my fuel rail along with my injectors to see if they are operating properly. But, other than that the only other possibility is maybe, just maybe the timing belt jumped a tooth, but I doubt it due to the way it just kind if died. Or maybe I got unlucky and filled my tank with some bad gas??

Any help would be much appreciated.

is it getting the right amount of spark?? just from what you say, it sounds like a weak/bad coil

I guess I'm just not too sure how much or what the right amount of spark is. How could I test that?

you want a bright blue spark... someone correct me if I'm wrong, but red, yellow, and orange all point towards a weak spark...

Well I did take a video of the spark it was throwing earlier and I do notice it to be somewhat of a redish color but it may be because I was using an old sparkplug.

I just don't know how it could be running fine one minute, then just not starting at all the next.

Doubtful. Highly.
Things break. It happens.

Well I got it started after really doing nothing. I got in the car to try cranking it over again and it actually fired up but sounded real rough.I held the throttle at about 2k and it soon smoothed out. I have no idea what happened but it works now.
