No power to my duel pump fuse or inertia switch was created by Jonnnyd23
1998 contour svt 2.5 I have no power to the fuse is slot 14. No power to the inertia switch. Seems to have constant power to the fuel pump relay. Any help would he greatly appreciated. I did rear a similar post on this forum but my car doesn't have a fuel pump module under the center of the rear seat, or in the trunk.

The fuel pump relay will have two wide pins, one of them should have constant power and the other one should be a constant ground (if inertial switch is not tripped).
As for the other smaller two pins - one should get power when key is in start or run position, and last one should get a ground, either key on (2 sec prime) or start and run.

Thank you. So for it to show power at the fuse, inertia and pump it will be the 2 sec prime or while cranking?

Good advice --- If you get power at the two of the slots on the relay socket with the relay removed while key on fuel pump prime then focus on pin 1 of the relay and pin 54 of the ecu and look for a ground on pin 1 when key on and fuel pump priming. If you don't get a ground re-fit the relay do the same test at pin 54 on the ECU.
