When I started it this morning it wasn't flashing, does it throw a different code than what's pictured to make it flash?
The CEL only flashes while the engine is actually misfiring, then it goes solid after the ECU stops the misfiring.
Your car didn't happen to misfire the next day, perhaps because it had cooled off.
If your CEL flashes continuously for more than about 30 seconds, you have most likely cooked your pre-cat.
You're not even supposed to bump start a 5-Speed P5 because of the unburnt fuel that goes through.
But don't worry about that.
There's an easy workaround to clear the code.
Your car is really sick right now.
Is there any way you can stop driving your car until after your fuel pump and filter are replaced?
It's getting really fouled up right now being stuck in limp mode.
You could be fouling or wrecking your O2 sensors and even damaging your main cat?
I'm not sure, but if this means short and long term fuel trim, it doesn't look right.
It may be proof that it's in limp mode?
0.0% and -100.8%.
