Ok here it goes....93 civic dx hatch with an h23vtec.P13 supposedly chipped ecu. I wired in the resistor box And it was a go. well then my number 1 injector goes. so i buy a set of dsm 390's, same injector goes. only this time the injetor resistance is fine, theres power at the shock tower harness.every injector measures the same for current and resistance all the same?? now as i understand there is always power at the injector and the ECU simply grounds the injector out to cycle correct?? i might try some inline resistors instead. Ill check back with the post i originally used to do the swap but what am i missing here??? I've searched several other places and came up with some troubleshoots but they're all variations of the same idea/method.
and yes im positive its not the injector because i switched the plugs around.
Im thinkin i can somehow check to see if the ecu is grounding properly.I would assume it would be to fast to see on a voltmeter...man wTF?? lol and it isnt even giving me a check engine light?? sometimes it'll even start working again.
the resistance is 7 on all but the one thats messed up and it reads 6
ANYONE???

obviously it sounds like your wiring.

 

and that sounds like a post count post....obviously theres a problem if it isnt the ecu but judging from the info i gave you wouldnt it appear that everything is correct..??? i mean theres power and theres resistance im askin what other method of troubleshooting i can use to see what exactly the cause is.because the 4 wires going to the ecu get grounded at the ecu right ?? and i would assume its takes place to fast to be seen on a voltmeter?? or no ?? the whole issue is kinda backwards to me.
