i can hear my fuel pump prime for 2 sec then while cranking no fuel comes out of the injectors. injector fuses good, inj resistance good, this is a intermittent problem. when fuel sprays she fires right up, no spray and it will just crank all day. sucks cause i can't trust to drive her. 1992, 305, 108,xxx all stock, had tune up (plugs wires fuel filter etc.) at 81,xxx miles. any ideas would be great. what tells the ecm to fire the injectors.

 

Two words for you: 'Ignition Module'.
