I previously posted about my '94 4.0 SOHC not wanting to start. Got some good info - especially about pulling the codes with a test light. Couldn't do the ER test (obviously), but got one code (besides the 111) from the KOEO test. Code 226 - Ignition Diagnostic Monitor (IDM) signal fault - Ignition Systems. I can't find any information with any teeth to it, though. Anyone have any ideas?
