As I replied by e-mail:
I would suggest looking at the wiring diagram for the fuel pump to work out that issue, no fuel = no start:
As you can see, it is a pretty simple circuit, battery feeds power to the 15A EFI fuse, then to the main relay that is turned on by the ignition switch. Then that feeds power to the circuit opening relay which is turned on either by the ECU's STArt signal (i.e. while the STArter is being used) or via the AFM flapper Fc contact or via the test jumper. If neither the AFM or the test jumper turn on the CO relay, then the CO relay may be bad. Check it out and work your way back to the battery. Changing the fuel pump when the old pump is not getting power will do nothing but lighten your pocket book, unless you have otherwise determined the pump itself is bad.
The heater blower is probably totally unrelated, maybe it has a bad switch or relay (in the center console area, passenger side). Or study the FSM wiring diagram and see if there is anything in common between the things that don't work, like do they get power or ground from a common connection?
