i did a dpfi to mpfi conversion when i did a d16a6 swap in my 89 hatch and the injectors arent gettin signal to work. so injectors 2 and 4 arent sprayin fuel.

yes i have a resistor box hooked up. i have four wires comin out thru the firewall from my ecu. if anyone knows about this kinda wiring conversion. please let me know. i need the help. or if u know what i did wrong. tell me. thanks tons. much luv.

Have you checked that the wiring for the MPFI conversion is working correctly i.e. the injectors are pulsing correctly? Just because there is fuel pressure at the fuel rail doesn't mean it's getting to where it needs to be. Listen to the injectors when you're cranking to see if they're pulsing (clicking). If not, I'd check the wiring that was added for the MPFI conversion.

 

they sound like they are clicking. i was listening to it before. and the person who had the car before me said that he thought it was fuel related. that the fuel wasnt gettin to it. but i figured id ask around. thanx for replying!

bump!

 

bump. come on guys.. please help. ive been workin more on it... but from what i can tell, the computer is telling it to spark cuz i have spark. and i checked to see if anything was stopping the fuel like clogs and stuff... but i found nothin. the fuel makes it up to that point... but i think somethin is tellin it not to give it fuel. idk. im havin a hell of a time.

if u got an idea. please let me know.

 

check ALL of your fuses
and then double check
then triple check

 

bump again. show some love.

 

It definitely sounds like your wiring for the MPFI conversion is incorrect. Only two injectors are firing, and there are only two injectors on a DPFI system. Hence, you need to check your wiring for the MPFI conversion. Or, something I just thought of.... which ECU are you using? I hope it's a PM6.....
