SOURCE: 99 Grand Marquis Fuel Pump problem

Lets try a new keyswitch and a fuel filter. The key activates the starter side of the ignition. This terminal should power both the starter solenoid and the fuel pump. Although the fuelpump runs on the ignition side continuously, you should be primed when the key is in the "on" position. I would wonder if the pump is cutting off too early meeting the resistance of a dirty fuel filter.

SOURCE: how can i change fuel filter in my grand marquis

you will need the proper Quick Disconnect tool, Look on the Frame rail for the filter, remove filter from the spring type retainer, remove the safety clips on the lines but not remove them completely, insert the disconnect tool & push into the fitting of the fuel line, push line & tool into eachother then pull filter away from line, if not done properly you will have a big problem putting the line back on

Check under the dash at your Brake pedal interlock switch. It is timed with the gearshift Interlock and Ignition switch. This switch usually gets hit by feet and dislodged or broken. When you shift out of Park, the switch is toggling to a broken piece and shorting out.

The brake interlock switch is at the top half of the pedal lever. The other part of the Interlock uses a rod or cable in the steering column Ignition switch and mates with the shifting mechanism.

Most parts retailers can tell you what the pressure should be from the pump or what pressure the pump is rated to put out. If pressure is low from the fuel pump- replace it.
