Sometimes after the car has been warmed up, and I go to restart it and it won't start. It will run or catch for 1-2 seconds but then die right away. This is a new problem and never had this issue before with the current tune so I don't think its the tune.

The only way to get it to start, is turn it off, wait 10 seconds so the main relay shuts down, and retry. Then it fires right up.

When I start it, I always wait for the fuel pumps to prime before I turn the engine over.

I'm running AEM v1.
