2000 V10 no start
2000 Excursion v10, auto, limited, 4x4, 160k miles.
Tried to start the X this morning and no start. Got down to 12 degrees last night, coldest so far. Unfortunately my F350 is parked in front of it so I can't leave til wife gets home. Zero issues before, drove 90 miles last night and ran great. Battery is strong. Truck cranks but doesn't turn over at all. All fuses good.
I don't have a fuel pressure tester yet but I unhooked the intake at the manifold and sprayed starting fluid in. Didn't help a bit. Pats lights seem to be blinking normally.
I'll pick up a fuel pressure tester tomorrow but I'm leaning towards crank or cam sensor instead of fuel pump since startIng fluid didn't help. Probably buy both just in case.
Am I going the right direction or should I be doing something else?
Thanks

I think you meant to say it doesn't fire, start or run.
Definitely check the fuel pressure.
Are the coils getting 12v with the ignition switch in Run or Start?
What is the battery voltage when cranking, it must be over 9.4v or so for the ignition to work.
I haven't been able to find a PCM logic diagram, but I've heard the crankshaft sensor is checked when Start is selected and enables the rest of the firing sequence.
If these check out the PCM may be bad, but I would check a few more things before replacing it.

If no fuel pressure the pump may not be getting power which is an easy test and may be the relay, fuse or wiring.
Also, the fuel filter.
You have a 2000 so the relay is easy to get to.
With fuel pressure and power to the coils, next likely would be the crankshaft sensor.

I guess it could affect starting if the PCM thought the throttle was wide open.
Hadn't thought about that before.

A failing TPS - Throttle Position Sensor usually exhibits poor idle, accelerating or stalling issues.

I have seen this on 7.3 trucks where the potentiometers in the pedal fail or get dirty and cause a rough idle or no start issue due to no Idle Validation.

I put a TPS on my old 7.3. Had erratic idle. Easy fix. This one has shown no symptoms before no start yesterday. Getting ready to test now. I have Scanguage2 with all pics programmed for my 6.0. Takes so long to reprogram though. I have a friend with a good code scanner coming over later.

Did you open up the throttle a bit when you sprayed the ether? Not much gets passed a functioning IAC.
Can you hear the FP cycle when you go key on?

After reading this I did open the throttle and got it to fire up on the fluid. Relays and fuses were good, no codes at all. Dropped tank and checked power at the pump and it had none. Pulled fuel pump, put in a new one and reinstalled tank. Put a new filter in, primed and it started right up. Running good again and I'm happy.

That's how I found out the carb on my generator was bad. Guy at the shop sprayer some starting fluid in the carb intake and it fired right up. $250 later I was back in business
