I've recently done a dual point to multi point conversion but im running obd2 injectors, so i ran the signal wire to the ecu and ran the ground wires (on obd0 you would run these to a resistor box) to the tranny ground, i've also put a new distributor on and ran the wires to ecu, but my injectors will not fire, i do have spark, but no fuel. anybody have any recommendations on why my injectors aren't firing

 

The injector signal wire from the ECU is the ground. The other side should go to +12V switched, not ground.

 

Thanks so much!!

 

Are you using obd0 ecu with obd2 injectors?

 

Yes

 

The yel/blk wire is the voltage source. on OBD0 it is 5v through the resistor box. Depin the connector at the resistor box and splice tehm to the 12v feed that goes into the box. Problem solved.
