i have a 91 dx hatch i did a mpfi conversion followed all the steps given 2 me. i have a obd2 motor, obdo dist. , obd1 ls ecu, obd2 injecters,. whe injecters are not firing i checked the wiring over and over again i also used a pm6 pinout sheet to make sure can any 1 heip me out ?

 

Did u wire your injectors to the resistor box? if so, you dont need the box with obd2 injectors

 

yea i did so if i dont need it wat should i do ?

 

because you have the injectors wired into the resistor box, they are getting limited voltage. the injectors you have require a full 12 volts and the resistor box is not allowing for that. take the 5 pin connector going into the resistor box, de-pin the connector and solder the wires together.

what this will do is bypass the resistor box and a full 12 volts to the injectors which is what you need.


*assuming all of the wiring is correct

 

ok thanks a a bunch im really thankful

 

i wired them all direct and they still wont fire
