zukijames Posted February 27, 2013 Share Posted February 27, 2013 Just put the motor in and has no spark, the previous owner modified the wiring harness(he's done several has a electrical business.) I've tested ignitors, coils, crank sensor, and cam sensors As far as I can tell the issue must be something with the signal and feed back wires from ecu to ignitors. I re ran the signal and feedback from ecu to ignitor on the 4 pin plug and still nothing Today ill try the other side Anyone got any ideas?

landar Posted February 28, 2013 Share Posted February 28, 2013 the previous owner modified the wiring harness(he's done several has a electrical business.) That fact is very troubling, IMO. I would want to know how and perhaps, why the previous owner would modify the wiring harness. If the ECU is not getting the proper signal due to errant wiring, I would not expect it to allow spark. Does the ECU throw any codes at all? Quote Link to comment Share on other sites More sharing options...
zukijames Posted February 28, 2013 Author Share Posted February 28, 2013 Well I might get looked down on for telling the whole story . I paid the previous owner to modify the harness for my project.. He had a business and has done some awesome work..but now he's not so awesome lately Anywho. Here is my lexus 95 ls400 motor to a r150f 5 speed tranny I've fixed the grill in this pic it's just up there to see how I liked it . Also I'm looking for a 2000 gs 400 trunk Quote Link to comment Share on other sites More sharing options...
