Answers :

Check in the trunk on the drivers side for an opening in the carpet. There can be 2 switches and 1 is for the Air ride and the other is a fuelpump safety switch. The safety switch is called an "Inertia switch" and it has a push button for Reset. Just hold the button down for 3 seconds and it will reset.

\012Then turn on the Ignition and you should hear the fuelpump run for a few seconds. It should be ready to start. If the Inertia switch was tripped it is made to kill the fuelpump upon impact. Slamming a door or the trucklid can make it kill the fuelpump.
