I pulled out of my driveway this morning, and my truck stalled. At this moment my check engine, ABS, brake and 4 wheel drive lights all came on. My truck wont start. I tested it with an OBD II tester and got no errors. The truck cranks but will not start. Has my PCM gone bad or is there another answer? does anyone have any suggestions. I lost my main source of transportation, it won't start.

Good morning,

If your car stalled and your not having any codes there is a very good chance that your fuel pump or fuel pump relay failed. Most of the other no start failures in a stall out condition will set a code. When you turn the key into the on position and listen carefully you should hear a humming sound for a few seconds. Listen for this and if you don't hear anything it's pointing to the fuel pump not turning on.

Here are a couple articles for your review that will help you get this handled:
