Richard,
After what I learned I would highly recommend testing all fuel injectors prior to installation, especially if they sat for more than 90 days after use or servicing.

Update… I sent my injectors back on Friday. Put the crank and belts back on today. Didn’t bother with the A1 timing test. Really hoping it’s the injectors.

The injectors have returned. Rebuilder says they’re good and flow well. At his suggestion, I measured resistance on temp sensors (was good) and put a vac on the hose that goes to the ECU. It held vaccumm all night.
So…Here’s a quick video showing a spark plug firing from each side. Does this look weak?
