2000 D2 not turning over
 

Everything ran fine until I put it in a shop to get the AC repaired, driving home it started to sputter and then just died (lights still working)
I got it towed to my house and replaced the battery, alternator and crank position sensor. The dash lights and everything work just fine and its not throwing any error codes.
I also replaced the fuse box under the steering wheel and double / tripled checked the fuses

I put it in the shop a second time where they just looked over what I had done and shrugged their shoulders. Working with some land rover guys we got the ECU and BECU flash and reinstalled. I disconnected the battery and installed the ECU and BECU reconnected the battery and it ran for about 10 minutes and died, I jumped the vehicle ( low charge on battery from sitting at the shop) and it ran for about 30 seconds and died again. After that I swapped the battery out for a another new one and still nothing.

I am currently looking at the fuel pump

If you guys could help with how to check fuel pressure and the proper way to check for spark (tools needed or step by step) I would really appreciate it !

If it’s not turning over I’m pretty sure it’s not the fuel pump. A quick and dirty way to check if you have fuel pressure is to press in the valve on the Schraeder on the fuel rail. If it sprays out you at least have some fuel pressure.
