2013 Ford Transit Connect; 2.0 liter; 325,000 miles.
Hello all, i am super frustrated. I have a 2013 ford transit connect. It will not start. The engine does turn over. I have no spark on any of the 4 plugs, checked fuses, fuel pump works but, no fuel passing through injectors. I checked the fuel shut off inertia switch. I know the injectors are not clogged because i not so safely used a 9 volt battery to test each injector while fuel system was pressurized from the fuel pump.
Now, i need to mention i had the head off for some valve work that needed to be done. I pulled the computer, battery, intake manifold, exhaust manifold and air cleaner all out for working room. I rechecked to make sure everything is connected correctly about 3 times. I am thinking Crankshaft position sensor or Computer as
possible problems. Any input will be extremely helpful.

You need to run a few more tests to get the whole picture.
All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.
Every engine requires spark, fuel and compression to run. That's what we have to look for.
These are the basics that need to be tested and will give us the info required to isolate a cause.
1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.
2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.
3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.
4) If all of these things check good, then you would need to do a complete compression test.
Once you have determined which of these functions has dropped out,
you will know which system is having the problem.

Any codes stored in the engine controller? If so, what are the numbers.
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

This may sound stupid but, if your are speaking of the OBD, under dash, then no codes. Other than the OBD. I have no idea. I am assuming the "engine controller" you are speaking of is the ECU (am i correct?) I called the Ford dealership, they said they cant scan the ECU unless in car and car running. Kinda the problem, i thought. If it was running i wouldn't have had to call them. Sorry for the rant, frustrated humor, i guess.

Yep, ECU is also known as the PCM.
If you can communicate with the PCM, that is a good thing.
As HT stated, you should check for fuel injector pulse and fuel pressure while cranking. If you have injector pulse, more than likely the ECU is receiving the crank sensor signal and you need to focus strictly on the ignition system.

When i was checking the fuel injectors. One of tests i did was crank the engine with fuel rail out, injectors connected and original wires connected, all as one sub assembly. I cranked to see if any fuel came out of the injectors onto the ground and no. So then, i disconnected the injector wires and used 9 volt battery and they opened and fuel sprayed out of the injectors while cranking engine. Not drip or seep, a pressurized spray.
I spoke to the garage i use on occasion. The mechanic said the computer may need programmed since i had the ecu out of the vehicle for a couple of days.

All of these things will show up if you do all those tests
