TREVTEC Posted December 29, 2005 Share Posted December 29, 2005 Doing a 1976 280Z turbo conversion. Has the stock N/A long block. I have added the 280ZXT Harness, ECU, MAF, distributer, Dizzy Shaft, Ingniter, pretty much everything. Im cranking the motor, I have Spark, and TONS of fuel. Takes just a few seconds to completely soke the plugs. Only weird thing I noticed is while I was checking to see if the injectors were getting power I noticed both wires on each injector get a 12 volt signal while cranking and even when Im not. Does anyone have any idea what could be wrong. Thanks. Quote Link to comment Share on other sites More sharing options...
GrayZee Posted December 30, 2005 Share Posted December 30, 2005 The injectors should have 12v power all the time. On one side, the other side goes to the ecu. Quote Link to comment Share on other sites More sharing options...
TREVTEC Posted December 30, 2005 Author Share Posted December 30, 2005 Thats right, but in this case both wires going to the injector are getting 12v. Quote Link to comment Share on other sites More sharing options...
ngrimm Posted December 30, 2005 Share Posted December 30, 2005 I think unless you unplug all the injector connectors you will see 12v on both wires due to the windings. Unplugged you should see 12v on one wire only. As you know, the ecu basically uses grounds pulses on the other wire to make the injector fire.
