2004 Honda pilot 6 cyl

HELP! First of all my hubby and I watch your youtube channel often. You are hilarious, even if you don’t try to be. lol.
Next. I have a 2004 Honda pilot I just got in february. 2 weeks after owning it, I had to replace the motor. Now, I have a flashing check engine light and a pending error code of p03199. This is like a huge pain in the ass as we have 4 kids and a baby due here in about 19 days. I am really at my witts end here. Our code reader also showed something about fuel injection control module. Any advice on what to do???
