1992 LS400 no spark at coil#1, +B voltage good at coil connector(primary) with ignition on
*coil ohms good(primary and secondary)
*cam sensor ohms good
*coil primary wires good continuity to IGNITOR #1
ALLDATA states there is no test for these, parts stores don't seem to be able to test these either
Note: with engine running if coil#1 primary plug is disconnected engine shuts off
