Seriously, if you don't already have a copy of the Service Manual, get it here:

Then, find Page 11-10 and read the troubleshooting/diagnostic procedure for a Crank/No Start condition. It will eventually lead you to 11-141 (Troubleshoot Fuel Pump Ckt.) If you don't feel confident that you'd be able to perform the procedure yourself, tow it to a shop. You can really screw stuff up if you don't know what you're doing when you're messing with wires and relays...
