Guest JohnBrison Posted July 26, 2012 Share Posted July 26, 2012 So I have a customer that has brought me a 93 NA/auto Mk4 supra. He also had a JDM 2jzTT and and a 6 speed. The engine came with the JDM harness and ECU. The car being a USDM and the harness being JDm it would not reach the passenger side of the car for it to go through the firewall. So the customer sent me a USDM TT harness. I hooked everything up and had a few extra plugs left over, 2 at the back of the intake manifold, and one near the chargepiping. Got everything in and hooked up and the motor will fire off starter fluid but other wise will not. And I used noid lights and cannot get a pulse at the injectors. Any help would be greatly appreciated. Quote Link to comment Share on other sites More sharing options...
