Car cranks but won’t turn on

2002 Mercedes C320

hello everyone I been working on my sons car for the past week, one night he came home and the next morning car won’t turn on, I checked all the fuses and relays, the car is not getting any gas In the fuel rail so I checked the fuel pump and the sending unit they got no power I checked the pump for voltage and 0 nothing relay and fuse is fine took out the pump and works fine with 12 v applied to it I also replaced the crankshaft sensor. I’m lost now he doesn’t have a lot of money to send it to a dealer he’s a college student so any help is greatly appreciated it

Hello and welcome to the forum! Did the CEL ever come on? If so, try pulling the codes; this should give you a good place to troubleshoot.

No I didn’t get any type of code the night before he said the only thing that showed was the oil was low. The next day I put a quart of oil and took the crankshaft sensor replace it and still the same, since than I took out the camshaft sensor got excited because I tested for continuity and show it was bad so replace it and still no voltage at the pump I’m still looking for the problem
