***UPDATE***

Alright, check the wiring schematic and found that the ECU fuse is ALWAYS HOT which means it should kick the fuse if it is the PGM-FI relay that is bad as soon as I put the fuse in, BUT IT DOESN'T (insert dramatic music here - DU DU DUAAAAAHHHH!)

The fuse kicks when key goes to Accessory position only, which eliminates another possibliity, the fuel pump. The fuel pump only turns on in ON or CRANK mode and the fuse is already blown in ACC position before it gets to those, which means the PGM-FI relay CAN'T tell the fuel pump to turn on, which is why there is no gas, NO STARTING (more dramatic music doo doo doo, DUDAAAAAAAH!)

Therefore, it is highly likely that it's something within the stereo (which I just installed a new one and electically taped many of the behind the dash wires instead of using crimp connectors). If any of those wires are coming loose from the tape getting hot and touching the body, it would ground out and blow the fuse on that circuit. (DAAAAH DAAAAAA!!!)

NOW, what I'm going to do is remove ALL fuses in the under-hood fuse box and try to start the car with only the ECU fuse in. It should start. Then while running I will put in the fuses one at a time until one of them causes the ECU fuse to blow and I'll know what circuit it is, then I can further diagnosis. More than likely I will be removing the deck wiring harness and securing all the wire connectors with crimp connectors instead of tape .
