absolutely not.

In this order: MAP, CTS, IAT can cause flooding.

Know what they have in common?

You might pull the vacuum line from the Fuel pressure regulator and see if it looks wet inside. If the diaphragm had a hole I guess it could suck fuel in that way. Easy enough to check/rule out anyway!
