I have never come across one of these without a tank pump,every one I've worked on has one so I'd recheck if I were you.
When the key is in the run position ,engine off,there should be a ten second buzzing sound,that's the fuel pump relay priming the system with fuel,and they just wont run without this.
My normal first step test with these is to remove the inlet pipe from the tank to the filter,key on,(ten sec burst),key off,and repeat 3 times letting the pumped fuel spill into a measuring pot,3 burst of the relay should deliver minimum of 250mlts,no less,and a pressure of 2.2 bar if you can measure it.
Electrical faults on these,and there are many,can usually be traced to the wiring harness where it runs from the r/h side engine bay across the gearbox and splits there,fauts can be anywhere in the run.
Fuel pump relay is up there as well and all are vulnerable to water getting in .
