Pin #2 at the MAF/IAT connector is the IAT signal. Matches your code. And you starting trouble.

This is helpful.
I have someone coming tomorrow to install the MAF sensor wiring.
Will update.

Rpm dsd is rpm desired by the pcm that value is the "desired rpm" there is also rpm actual. Rpm desired never moves at idle.

Banged on several ford and gm map sensors to get the engine to fire. Sure like seeing it on a computer. Used to tell people dont just go out and buy one until you get stuck at least one more time and smacking it fixes it again.

have a Ford guy on site, he thinks the injectors are not grounding. Possibly the computer faulty, the driver module in it. He checked it with a device that lights up.

Yes, IAT is all good now, reading 26C, no codes with anything. KOEF test no codes. But does not start.

The MAF sensor has been fixed, which cleared all codes.

Replaced the camshaft sensor, still no start. I think it's the computer.

The crank sensor swap actually made it start. Although the crank interval is still pretty damn long and only starts on the 3rd time.

Check your scan tool to see if it supports a crank position sensor relearn. Relearn is supposed to be done when crank sensor is replaced.

Also, performing a sync between the cam position sensor and the crank sensor would be a good idea, if your scanner can do it.

It definitely was the crank position sensor. It started starting, gradually better and better. Today started without hitting any throttle at all. Cranked for 6-8 seconds and then started. It must be relearning. I have not driven it yet.

Upon examining the crank pos sensor, some oil was on the connector. Resulting in weak/ intermittent signal.

The faulty crank pos sensor was not picked by any scanner. It had zero codes on it after fixed MAF. Actually my Forscan scanning software said that crank pos and crankshaft were in sync. My mechanic's Ford scanner said they were intermittently syncing, and also the noid light was intermittent.
