There are other causes of your problem but most probably a fuel pump (accessible from the rear seat) or fuel filter (engine firewall, besides brake booster) is clogged or failing. To verify, you need to connect (T-fitting) a Fuel Pressure Gauge downstream of the Fuel Filter. With the pump on, pressure should be >40 psi
Ensure the fuel line is empty before connecting a fuel pressure gauge - FIRE HAZARD. To do so, pull the Fuel Pump fuse with the engine running until it dies. Crank the engine at least once to ensure line is empty.
On a good fuel filter, you should be able to blow air thru it w/o restriction. Otherwise, it is clogged.
