I have a 91 honda civic lx with dual point injection system. My check engine light is saying to check the fuel injector. I check the resistance and they were within the specs of the chilton. So is there any way to clean them out? I would use an injector cleaner but i cannot get the car started.

 

I pulled the airbox off and looked at the injectors. The main injector is spraying fuel fine. The auxilary injector isnt spraying at all. Is this correct or are they both supposed to spray. My check engine light still says that it is an injector. Can anybody help?

 

anybody?

 

check for a break in the wire. or if they are the same injector swap them and see if it works.

 

the injectors are different sizes. i check the connectors with the ignition on and both are getting 9 volts i believe, if not 9 then 12 volts. i cant remember because i did it a couple of hours ago.

 

ok.. you have to do some diagnosis now.

do you have a volt meter? a digital one? No?? go buy one. Ok.. now that you have a multimeter un cover your ecu. Check for continuity between the secondary injector wire where it plugs into the ecu (im not sure which wire that is) and the other end near the injector. If there is continuity (meaning the wire is not broken anywhere) I would spring for a used injector from some1. (im sure u can find TONNES of these since many ppl do MPFI swaps).

 

yes i have a digital mulitmeter. i have already checked the ohms on both the injectors and they are within the specs stated by my chilton. I also checked to make sure that the wires have continuity. So i am just going to replace the injector. Anybody got them?

hey i know your problem, replace your fuel pump relay, my wifes car just did this too. Said faulty injector, wouldnt start. Replaced the relay(which btw is a bit*h to get out) and car has been running great ever since.
