I understand that both secondary injectors are supposed to have twelve volts at all times while the car is on and at 3,800 rpm the secondaries are grounded by the ecu to activate. My question is, "Why am I only getting twelve volts to one of the secondaries? The secondary closest to the front of the car has no power what so ever. Thought there might be a break in the wire somewhere but I checked the secondary injector wire (probed it) right out of the ECU and no power there. It is a light green wire with a white stripe. The other secondary closest to the fire wall has power right out of the ECU and of coarse at the injector. Does this mean the ecu is trash? Other than that, the new 13B runs great.

 

Forgot to mention that the motor has been street ported with racing b header and full exaust.

 

I snatched out the ecu, found a burnt resistor. No ohms crossing it from meter. Bout to solder a new resister and it should take care of the prob

 

Curious, did it work?
