L1 & T1 not firing??Driving me nuts!

the L1 and T1 plugs show no sign of being used, clean as a whistle. The other two plugs are blackened. They are new plugs but I've been fiddling with some problems. She stalls out when hot too. Is this a timming prob? Wires new, coils test ok, injectors grounded, TPS fine.

If L2 is firing, then L1 is firing. Its the nature of the Lead coil/ignitor assy. Can't have one without the other. Not true of the trailing coil/ignitor. It is possible the L1 is shorting to ground on the way to the plug, and the L2 to fire. Lay the L1 wires end next to the studs and nuts that hold your l/h strut in place and start the engine. Should see the wire arc a spark to ground. If the front rotor was not firing, you'd have ungodly hell starting that car, although it may very well start and shake all over the place.
