Matthew Way Posted September 16, 2006 Report Share Posted September 16, 2006 I have just put a new Toyota 1UZ (V8) engine into my Supra (it had another 1uz before that). And finished wiring it all up with the LEM v4 that was previously on the old engine.At the moment I am not getting much spark, there will be an intial spark when cranking but nothing after that. Occasionally when turning off or on power, there will be a spark as well.I have checked and fixed wiring to Cam and Crank sensors, but could it be a faulty sensor causing this?Is there a way to test that the 2 channel igniter module is doing what it is supposed to?Is there something else other than those two sensors that could be preventing the ECU to stop sendingÂ ignition pulses? Thanks Quote Link to comment Share on other sites More sharing options...
