I replaced faulty ignition starter switch (worked but had excessive drag and binding). Also found low voltage at fuel pump inertia switch (2.8 volts). Jiggled wires at ign. Starter switch and they rose high enough to run pump, but not any more. Wiring/contacts/plugs look perfect. Engine cranks great. All the bells and whistles work except pump and I know it's good. Please help it's my mother-in-law's car and I'm tired of working on it. I would love to donate but I'm maxxed out on my cards.

Check the ignition switch and fuel pump relay

Where and how do you check it? These books now-a-days leave out way too much

Get your ignition switch tested if you have to do this for the fuel pump to come on.
