Yes, with your ignition switch on, you should have voltage at both ends of the inertia switch for 2 to 3 seconds. That is if the switch is working properly. The red button on the inertia switch should be pressed down, and should stay down. When it is down, voltage should flow through the switch then to the fuel pump. If your engine is not starting, (like in your case) you will only see voltage for 2 or 3 seconds. So, have someone turn your ignition switch to the on position while you test for voltage at the inertia switch. Test both sides of the inertia switch. If you don't have voltage at either end of the inertia switch with your ignition switch on for 2 to 3 seconds, that would indicate problems with your CCRM. The CCRM is a multiple relay module which supports various circuits, the fuel pump is one of those circuits. If you do have voltage at both sides of the inertia switch, then test the wire connector at the rear of the gas tank, just above the bumper. Disconnect the wire connector and test the side that runs to the inertia switch. If you have voltage there with the ignition switch on for 2 to 3 seconds, that would then indicate that your fuel pump went bad. I'm thinking you are testing for voltage by yourself, and by the time you get to the inertia switch, the 2 to 3 seconds has passed by and that's why you don't see any voltage at the inertia switch. Let us know how things turn out. Hope this helps, Tommy.
