My injectors are fine and ive tried 3 different sets all working. My harness isn't getting the right power through the clips. It stays constant and when I put a test light in the clip it doesnt flicker like it should. What could be the problem? I have fuel at the rail and good spark but something with the harness isnt telling the injectors to pulse.

 

need more specific info. what injectors, what motor, what ecu...

 

92-95 civic si OBD1 injectors
JDM b16a
P28 ECU

 

bump

 

Did you do any re-wiring?

Do the injectors actually have battery voltage present on the Yel/Blk wires?

 

yes there was some rewiring but nothing was touched on the injectors. everything else seems to be working fine. They have battery voltage it seems like they aren't getting a signal from the ecu. I ran wires directly from the ecu to the injectors also and the same problem is going on. I know it can't be the ecu because ive tried 2 p28's and they both work fine in other cars.

I think this thing is cursed!!!

 

What wiring was touched though?

 

mostly just distributor wiring but I have spark, i tested them

 

I know this thread is old but im now having the same prob with my obd1 ls/vtec in my 89 CRX. Im am also running a chipped p28 and have tried 2 different ones that work in other cars. I have spark and I am getting fuel to the injectors, but they just arent firing.

HELP PLEASE.
