@Toasty, I will look up ‘control module', doesn't ring a bell offhand.
@evomaki, nope still not running. Been doing a lot of multi-meter checking between ECM/harness and other components (nothing definitive yet). Have the front of the motor pulled apart to get to crank/cam position sensors but didn't realize I needed to pull crank pulley/bolt to get lowest cover off. Didn't have the tool to hold the crank pulley in place while removing bolt so waiting until Fri/Sat when I can borrow a buddy's tool.
Hopefully make a dent in it in the next couple of days.
