OK guys, I have an 03 MC, 17K miles. The car runs, or ran, great. I filled up with fuel today, drove home from work, the car worked perfectly, I pulled into my driveway and parked. I went out about 2 hours later to go out and the car would not start. It cranks fine, all lights work. I checked all engine and fuel related fuses with an ohmmeter, all are fine. The fuel pump relay and the ignition relay are both pulling in. I have tried leaving the key in ignition for 5 seconds before start, I have tried both my keys. I don't hear a fuel pump, but I don't think that I have ever heard a fuel pump on this particular car.

Any ideas?

 

Update.

After the car sat overnight, it started perfectly. So no permanent failure, just a transitory issue. Even more strange.

 

I had this problem. After I made sure the plugs into the coil pack and the throttle body were snugged tight it disappeared.
