Hard time starting the engine up?

So I did some research and found out that only denso sensors are good with Toyota. The new maf was purchased from advance auto. I scanned the live data and the IAT was reading 132 when the temp outside was only 83. So took the new one out and put the old one in, IAT read 100. But gave me MAF code. Also the ECT was reading 199. Here are some pix of the live data. I'm thinking about getting a denso maf

How would I get the actual coolant temp compared to the scanner reading?

Update. So I cleaned the maf and tested it with a multimeter and it's all good and car starts right a away with no problem. I still have the p0171 code and on the ready page on the scanner, everything has a green check mark except the cat and o2 sensor with have red x mark. Could that be causing the p0171? The upstream o2 sensor is good and new. Could the downstream o2 sensor be causing this?

So then do you suggest that the vacuum leak or p0171 is causing the cat and o2 sensor to not read ready?

Ok so I put a new maf sensor and still the same. Did a vacuum leak test and nothing. But, I put my hand under the catalytic converter and there is hot air coming out from a very small hole at the front side of the converter. Not the joints. Could that be causing the problem since the scanner showes cat and o2 sensor not ready?

Did you ever get this resolved? Having similar symptoms with a 2007 Camry - P0171 code running very lean. 45% LTFT. It won't start when engine is hot until it cools off. Have done smoke tests, intake manifold gasket, valve cover gasket, plugs, fuel injector service, MAF, upstream O2, and a number of other things. Fuel pressure and crank sensor next I guess.

Very hard to start, some time 3 or 4 times need to try but some time starting smoothly
I checked pugs all are OK

As you said, I checked coolant temperature sensor then found loose connection on the connector.
After I connected properly, the probles is solved
Thank you very very much

Sir.

This car has a unique problem as it does not start once engine is cold. It requires a long key-self to start. Immediately after starting its starting is okay, but a second attempt even just 30 minutes after parking it requires a long starting. And immediately after starting when the engine is either cold or hot.
I have changed spark plugs, fuel pump, salf, heat sensor and battery. Everything seems okay.
Your kind suggestions please.

Furthermore I have checked it at many mechanics including the dealership, but so far problem still exists. I also had a complete tune up done. But it still requires a long starting after being parked. Second start immediately after engine switches off is okay.

Sir, fuel pressure I just checked with a guage. It is not losing the pressure, it remained normal even aftr 30 minutess. Your kind view please.
