Purpleline Posted May 28, 2020 Report Share Posted May 28, 2020 I have this very weird problem. It does has iinjector pulse in the 1st few starts. I remvoed the cas out( changed fm 33 to 34 cas as rb25 neo swap, switched pins already). Spin the CAS injectors and sparkes are both fine so CAS should be swapped correctly..even the trigger test is fine. I saw consistance waves. After few more attend to start it up. It just fire for less than a sec then stall. Lose injector pulse even i use the injector test. No error code in PC link. Pulse look all ok in realtime....even put a new injector on #1 and conduct injector test,.nothing happen again. It does work fm the very begining. I could test each injector and hear they click 1 by 1 Im now runing out of idea. What could cause no pulse to injectors? 12V is ok.. just ground, No pulse.... I even put a new g4+ ecu in, known working r34 CAS... same....start for 2 sec and lose pulse... Any suggsstion to narrow down the possible cause?

Adamw Posted May 28, 2020 Report Share Posted May 28, 2020 Sorry it is not clear what the problem is. Are you saying even if you set an injector output to test mode, you only hear the injector clicking for a short time then it stops? Quote Link to comment Share on other sites More sharing options...
Purpleline Posted May 29, 2020 Author Report Share Posted May 29, 2020 Yes, it work for awhile then not anymore Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 29, 2020 Report Share Posted May 29, 2020 Can you remove the injector wire from the ECU and test it with just test light attached to the pin. Maybe it is shutting down due to over current. Quote Link to comment Share on other sites More sharing options...
Purpleline Posted May 29, 2020 Author Report Share Posted May 29, 2020 Ok. Thats make good sense. They should be all 6 reading 0V?? Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 30, 2020 Report Share Posted May 30, 2020 They should be near 12V when off, and when in test mode you should see a short 2ms drop to 0V, 10 times per second. Quote Link to comment Share on other sites More sharing options...
