Note On Intermittents
Probe fuel pump test terminal using a voltmeter to ground. Fuel pump test terminal is located on left inner fender panel, near battery. With ignition on, observe voltmeter. Voltmeter should indicate battery voltage for 2 seconds and then drop to zero. If voltmeter stays at battery voltage longer than 2 seconds, check for sticking fuel pump relay contacts. Repeat test several times.
Continue probing fuel pump test terminal to ground and crank engine. Voltage should drop immediately to zero when cranking stops. If voltage does not drop immediately, check oil pressure switch for sticking contacts.
