My daughters 1998 civic 1.6, will not start. It quit on the road, and hasnít run since!
Turns over but no spark!. Replaced distributer and ECM. -- Have heard talk of ignition problems on these cars?? I really donít have any indication of this problem that I recognize?
Wonder if bad crank position sensor could cause this problem. Reads about 2 k ohms, which seems fine for a magnetic PU?
Would be nice to have a detailed schematic of the distributer and applicable wiring. Any ideas of where I might get these?.---- Chilton manuals very limited.
Civic has 140 k mi. Decided to give it a miner overhaul while in my shop. Hope I can get ignition to spark when Iím done!
Any help appreciated. Thanks
Did not check fuel prime. Codes showed nothing.
Did not check blk/yel voltage. Will check sensor resistance and wire voltage.
Wont be able to do much right now as I in the middle of an ovehaul because of poor compression.
Thanks. Ill do those things.
its your ignitions switch more than likely. I have a 98 and there are a million or so recalls for 98 civic's on our ignition switches. But mine never died like that, it would die when driving. check your main relay(also fuel relay) they are the same thing.
I bet money its one of those 2. good luck.

Those fuses and many more checked. found none bad. Ground was good.
Are you saying, if fuel pump don't prime, then won't get spark, as they would be on same circuit? --- When things get back togeather will check.
Note: Don't belive lack of fuel was problen, but definatly the lack of spark.
Will check all these things when I get things back togeather again.
I'm thinking bad ignition swith also, allthough most swith failures I've heard of were inttermitant! This doesn't seem to be that way.
That"s why I was hopping to be directed to a detailed wiring schematic.
Will recheck that relay! Thanks
most common failures to check first would be:
-the main relay; failure will cut fuel pressure (fuel pump won't run), but i think you will still get spark.
-ignition switch; like bghayd said an issue here typically causes intermittent failure. depending on which connection(s) is bad it could also keep the starter from spinning.
-coil and/or ignitor (ICM); these two components are housed within the distributor. in my experience they are prone to failure above 150k mi. you'll see compression and fuel but no spark, and it can fail while going down the road....
i can try to find a step by step diagnostic precedure for testing each of those components.

I did change distributer, and seperatly, installed new coil, Still no spark.
All else seemed to be working. (did not check fuel pressure).
Should have engine back togeather in a couple days.
Will check out pressure and all else you all have told me then.
Still open for ideas. (maybe websites, procedures and good schematics)
PS: As an old (really old), back yard mechanic that I am, I was wondering where the capacitor for this coil is? -- Is it external or within the distributer?? -- Did they somehow do away with it???
(just one of the reasons I wanted a good detailed schematic.) Thanks
If the dash warning lights illuminate when the key is turned to ON(II) or ON(III), then the ignition switch is likely fine.
Though you know there's no spark, you also need to listen for whether the fuel pump primes because, if it doesn't, then you need to consider the main relay circuit, which supplies power to both the fuel pump and ECU, which is needed for spark.
Did you check the three main relay fuses (44, 31, 13) using this method?
When you turn the key to ON(II), with or without the service connector jumped, does the CEL remain on steady?
Great site on fuses you showed me.
I agree probe method gives more info per check. I have a probe somewhere but didn’t use it.
I will have to disagree with the very first sentence on the site however.
A fuse can fail with overloads or surges over time, not just a direct short to ground.
When I get this thing back together and battery hocked up, I’ll go back and check all again. I’ll check that relay for sure. Hopefully a little more systematic this time, with info you people have given me.
