97 honda civic non vtec
my car doesnt want to start once in a while, i pulled off the cap and rotor to test the ignition coil... specs are 0.63-0.77 I am getting .9 for the primary winding and the secondary winding is within spec dont remember exactly what it was.. would that little bit of difference cause a problem??

 

Is there bright white spark at all 4 spark plugs?

Click the spark link in my signature. Did you subtract the internal resistance of your multimeter?

 

my dmm's resistance is .2 so i guess im within spec for the coil resistance

 

im going to put it back together and check each plug

 

put everything back together and it started. Looks like its a morning problem? could it being cold affect certain part of the ignition??

 

can the icm/igniter be working on and off?

 

ok, so ive been messing with it for a while, i have spark... what i dont have is ground signal at the injectors??
my fuel pump wasnt priming so i bypassed the relay (fused with a switch) so i have fuel pressure. If i touch ground to each injector they will click open and car will start but wont start back up after i turn it off

any ideas??

 

Sounds more like main relay

i had switched in a new main relay and same thing... took it back

 

i put the main relay back how it was (not bypassed) and the turn the key to on.. anywhere from 30 seconds to a minute or 2and it clicks and starts to prime the fuel pump? sounds like the main relay is bad, but when i had put in a new one it wasnt doing anything??? what else could affect it.. already cleaned ground g101 or somthing like that (thermostate ground)

 

Might be a bad ECU.
