Info for Bump starting a TD5 and checking injectors with a Nanocom

Back on the TD5 Defender, this time with a nanocom and I'm still struggling to get it to fire.
It's had a recon gearbox before I got to it. when I put the Nanocom on it was showing zero RPM while cranking.
I discovered the CPS was not plugged in DOH. Multiplug connected and it's now showing 200rpm when cranking.
The fuel pump is running when the ignition is on.
It appears that the injectors aren't firing at all as it doesn't even attempt to fire.
I've cleaned the terminal that runs from the starter to the injector harness, replaced the injector harness, had the ECU checked by ECU Testing. The Nanocom shows no faults standing.

I'm wondering, is it possible to test fire the injectors with the nanocom and if so what's the process?

Also, in order to rule out a faulty starter motor stopping the injectors firing, I've read a couple threads suggesting bumping the vehicle off.
What is the process for this? Is it as straight forward as just ignition on and tow it off and drop the clutch?
I thought I had read that you may need to remove the starter solenoid and turn the ignition to crank as you drop the clutch?

Any thoughts gratefully appreciated!

All I did was 2nd gear, ignition on, tow it and foot off the pedal when you're ready.

Just seen this

it must get above 250 rpm to start, see the battery voltage while cranking, if it drops below 10.5V it will hardly start cos it needs more to open the injectors

it's in the "Outputs" menu last line... better read the user guides available here https://www.nanocom-diagnostics.com/downloads

Brilliant, thanks for the reply. Its a new battery and fully charged and was only showing 220 rpm at the first attempt. Voltage was 12.7.
The crank position sensor speed reading was stable with no apparent interference/fluctuation. so I thought it was ok. The starter sounded pretty quick so I thought it would be OK. Perhaps the CPS is on it's way out and reading low.

I will try bump starting it in second gear and see if that gets it to fire.

I have found the injector test function on the nanocom and have gone through each injector and get a 'click' sound from the injector when I press the test button. I was wondering if it is possible to remove the injector from the head and test fire it to see if it is actually firing fuel.

I will go back to it later today and have another mess around now that I know that it needs to see 250rpm or above to fire the injectors.

was that while cranking? ...cos that's the only relevant reading... also dont try to crank it when you try to bump start it
