I currently have no spark. I have a 1uz with G1 V5 that I did have running at one point. The ingitors get hot after cranking the engine. I connected a test light from the battery to the negative terminal on the LH coil plug and it only comes on for a couple of seconds after the engine has stopped cranking. Shouldn't it pulse while cranking? Also occasionally the RH coil makes a buzzing sound after cranking. I'm well and truly baffled? Any ideas?
