Default 2014 GX460 turns over but won't start

Turns over, but won't start. Codes P1613 (Secondary Air Injection System Driver) and all coil codes P0351, P0352, P0353, etc. I'm unable to download the manuals - can't do zip files. Thrown some darts without success... disconnected MAP (still won't start), verified my CIN isn't included in the recall for FP, verified the SAIC is the new filter type. Without the manuals, I'm now at the point of getting it towed to the shop which I'd rather avoid! Any advice?

I’m on device not easy to look up FSM but do not recall seeing simultaneous multiple coil codes along with SAIP.

What kind of vehicle history can you provide? Has it been off-road, in water, electrical add-ons?

Minimal off-road, hasn't been swimming that I know of (bought used 3 years ago)...no upgrades or mods.

If you have >125K miles wonder if you might have a bad/fouled spark plug?

Is secondary injection control the device in front of the air filter box? Have you opened it? A piece of foam in the box can go bad and stop air from
going in. This is a known Toyota/Lexus problem.

Thank you all for the feedback and support! Turns out the engine harness & other wiring was chewed up by rodents...

Before I got my GX I had a RX that was a yard dog. I can't tell you how many times that rats chewed up my ignition coil wires. I started putting Victor Rat Traps on my engine and caught several. My GX is garaged so I don't experience the damage anymore.

Damn, I've been there with my old car that was a Lincoln Aviator. It was during a hard freeze we had in Texas and I parked next to a trash dumpster. Came out the next day and an entire rat family took refuge on my warm engine and chewed up a main harness.

Went a salvage yard and got one from a Ford explorer and spiced it to the damaged one.

This happened to my wife's car during the recent freeze we had here in TX. Luckily, it was just some harness for the exhaust side which is at the very front of the car. After a free code reading for the CEL at AutoZone, I was able to find it myself. It was an easy fix, which I did DIY.
