Default 2008 Camry Cold Start valve

I am having an issue with my 2008 Camry 2.4, 220,000 miles. It takes 2 times of turning the key and cranking over before it actually starts. Battery checks out good, new starter, new plugs. Always on the second crank. I turn the key on for a few seconds listening to the fuel pump. Once itís started it runs fine, engine idles smooth. I am at a loss as to what is causing my issue. Wondering if anyone else has ran into this. I think itís the cold start valve but canít find anyone who sells it for my year and model almost like it doesnít exist. Any help would be much appreciated

The engine has no cold start injector.

The fuel pump will only run when the engine is turning over during start or running.

Is the starting constant or just a first time the engine is started the next day issue?

It is consistent, does matter if itís the first start or the last start of the day or the temperature outside.

Any time period (minutes or hours) when the engine will start better? Such as you get gas. The engine is off for 10 minutes but restarts OK.

Itís a constant issue. Doesnít matter on time, I drive it every day. It always takes me turning the ignition over twice all the time every time. Like I said I can hear the fuel pump before turning it over. Since you told me there is no magical cold start valve I am back to square -1. I bought the car 18,000 miles used/new and have owned it since. I am now at 220.190 miles. I do all my own work. I took a stab by buying a new starter thinking it was the issue, but I am truly at a loss with out spending more money on stuff I donít need yet. Any help or more questions are much welcomed maybe it will make me think more about the cause.

If the engine turns over at a normal speed when starting, the starter is not the issue.

Can you check fuel pressure? Its possible the pressure is not up to spec or the pressure is bleeding off between starts.

The pressure regulator is connected to the fuel pump.

Might try jumping the pump wiring to have constantly on and the system pressurized. Then determine if the starting improves.

Also try cleaning the MAF sensor.

Just a quick update, cleaned the MAF and throttle body only because I was there anyways. No change on the starting issue. I will update again after I jumper the fuel pump.
