1997 W202 C180 Fuel issue

[Johnyk]

Hi guys. I'm from South-Africa. I have a 1997 W202 C180. I have an issue where I have spark on all 4 plug leads. I have power on al 4 injectors, but as soon as I crank, no fuel spray at any injector. Fuel pump is fine, priming as it should. I hear the fuel pump relay. When I spray fuel into the air intake, It wants to start, so it means I'm not getting any fuel delivered through the injectors. Any ideas?

Could it be the PMS that isn't working?

Could it be the fuel pump is breaking down under load? Prime pressure is different to delivery pressure.

Have you measured the fuel pressure with a pressure tester? 3.8-4.2bar is the spec value.

I'll take the car to somebody who can test everything. I was hoping it could be a yes or no type of problem, bit it seems way more complicated than that.
