I was driving home, and it just quit running like you turned the key off. I have been doing some trouble shooting myself and found out that I'm not getting power to the fuel pump. Jumped it with a hot wire and it came on. Any suggestions for what to do now?

When you jumped the fuel pump did the engine start? There are many things that can make the fuel pump relay not turn on like a bad MAF, crankshaft angle sensor, bad PCM, let's run the codes to see what is stored in the computer. This guide can help:

We should check the fuses as well, Sensor1 and IGN Coil fuse in the main fuse panel under the hood, this guide can help:
