Do you smell gas at the tailpipe? Take out a plug after cranking & see if it's got some gas on it?
Jumper those fuses to run the pump. On our '89 I could clearly hear the fuel flowing in the rail, if I was listening in the engine bay. If the filter was plugged, I suppose you'd hear the pump but not the flowing gas?
Look in the C900 FAQ, there's one called LH overview, go all the way to the bottom. You can trigger the ECU to cycle it's valves & stuff, try that. Listen when it's cycling the injectors.
