Just because there is fuel to the fuel distributor mean that there is enough PRESSURE to have the engine run. The fuel pressure needs to be at least 60psi to open the injectors. System pressure needs to be around 90psi.
Also very common for the idle air hose to come off & then not have enough engine vacuum to allow the air-flow plate to open and allow fuel to be injected.
