Question
ran out of gas started up ran about 2 blocks then turned off and cant get it to turn on again

Answer
.Here is a test procedure to see if the fuel pump works when your problem occurs.

1. Remove the gas cap.

2. Have a helper listen at the gas cap opening.

3. You, Turn the ignition switch to the ON position ONLY, Do NOT try and start the engine. Your helper should be able to hear the electric fuel pump motor run for only 2 seconds and then it will stop.

4. If your helper can hear it run for the 2 seconds and then stop, this means that the fuel pump relay is OK and that you have a problem within the fuel pump as it is not pumping gas to the engine.

5. If you do NOT hear the fuel pump run for the 2 seconds and then stop, Then you have a faulty fuel pump relay, or a faulty fuel pump.

6. If the fuel pump is OK, You need to check for spark to the spark plugs.
