1999 Dodge Neon
Drove my car two miles and shut it off, the next morning not getting any fire to plugs and no fuel, but fuel pump is good, keep blowing fuse for fuel pump, put on new coil pack and computer same problem.

First check the wiring harness for the oxygen sensors to see if it fell down onto hot exhaust system parts.
A simple trick to finding a short is to replace the blown fuse with a pair of spade terminals, then use small jumper wires to connect them to a 12 volt light bulb. A brake light bulb works well. When the circuit is live and the short is present, the bulb will be full brightness and hot so be sure it's not laying on the carpet or against a plastic door panel. Now you can unplug electrical connectors and move things around to see what makes the short go away. When it does, the bulb will get dim or go out.
If you find the test bulb lights up for just one second after turning on the ignition switch, you'll have to bypass the automatic shutdown relay to keep the circuit live to allow you to do some troubleshooting. Jump terminals 30 and 87 together.
