Hey guys so here's the situation the motor is a 1UZFE, tested for spark and I am getting one spark on each side which is the centre of the cap and rotor (plugs 7 and 8) so I took off the caps and saw they were pretty corroded/dusty so I replaced them both. The coil packs are obviously working because when I unplug them from the caps I get no spark at all. igniters are also good. My ecu is just laying on the floor does it need to be grounded to the chassis? I am stumped because I figured replacing the cap and rotors would solve the issue since I'm not getting spark on any of the contact points, just the point that has a constant connection. Any help would be much appreciated! Thanks for your time
