Getting harder to start

So i got my hands on a OBDII reader and checked, apparently AN Ford cleared the MIL cause i get 3 issues, all relating to my secondary air pump.

P2441- Secondary Air Injection System Switching Valve Stuck Closed Bank 1

P2443- Secondary Air Injection System Switching Valve Stuck Closed Bank 2

P2445- Secondary Air Injection System Pump Stuck Off Bank 1

My I/M readiness says EVAP (Evaporative System Monitor) and AIR (Secondary Air Monitor) tests are inconclusive.

Could that cause this issue?
If so any clue how to fix it? Would the engine tune-up Toyota wants to do help?

Yes it could cause some of the issues.
A standard tune up wouldn’t cover that BUT Toyota is apparently covering them on some of the second gens due to them being a faulty part.
Take a look at this link on Tacoma world.

I will have to look into that, I received no such letter, but I also bought it at a FORD dealer lol.

Thanks

You could hook a VOM to your battery and have someone watch the meter while cranking the engine. If the voltage drops excessively, it could give you your problem. Off the top of my head, 9 volts or below is an excessive voltage drop.
