A rare T-0 abort from Falcon 9!
UPDATE #8: Launch Abort. Will provide new data once it becomes available.
Standing down from today’s Falcon 9 launch. A new target launch date will be shared once available
Checking in with the SpaceX recovery fleet for clues, it looks like the Starlink 10-2 mission is standing down and the next mission from SLC-40 will be SES-24.JRTI droneship appears to be heading to the expected LZ for SES and Doug looks to be returning to Port Canaveral.
Tough week dealing with production challenges and then a rare scrub at engine startup yesterday on 10-2. Unfortunately there is a real issue so we need to go inspect the hardware in detail on this vehicle. Rocket will get set to the side and we’ll pivot to SES as the rocket and payload are ready to rock. Painful, but safety and reliability are the priority. This will be the first week we’ve gone without a Falcon Launch in a long time. Unplanned downtime due to weather or unexpected issues happens, it’s how we respond that matters. The Launch business takes grit and when things go wrong, our true form comes to life. Bring it on!!!

When was the last launch abort post-engine ignition? I feel like I remember one early this year or last year.

But after watching the video, I'm not sure the engines start up.Starlink 6 on March 15th 2020 definitely aborts at T-0.https://youtube.com/watch?v=Bkf-CU0ROLA
Didn't that happen on the first launch?
Saturday’s launch was aborted when the flight computer detected slightly high pressure in the engine 5 combustion chamber. During rigorous inspections of the engine, SpaceX engineers discovered a faulty check valve on the Merlin engine. The failed valve was replaced on Saturday and after thorough analysis the vehicle has been cleared for launch.

If someone comes up with a better answer, I'll stand corrected.
