Hello everyone I have a 1995 LS 400 with 353k and I can not get either coil pack to fire I have replaced Crank sensor , and the ECU both factory parts and I can not get the coil packs to fire up with the car is turning over ( my mech. )says lack of ground but when the key is turned to the off position I have a ground to the coil packs, but as soon as the key is turned on we lose the ground and do not get a spark to the plugs any ideas please inform me if anyone has had this issue and how was it resolved Thanks Gary
