    your owner manual will tell you.

    the power relay powers up the powertrain control module (PCM). the fuel pump relay powers up the fuel pump. Sometimes located near the module (PCM). I think left kick panel.

Will a 2003 mercury marauder engine fit in a 2000 grand marquis


Yes they both use the same basic 4.6 Liter V8 engine, the difference is the Marauder engine is a higher powered and uses Dual Overhead Camshafts and 4 valves per cylinder (DOHC) the Grand Marquis is Single Overhead Camshaft (SOHC), it will bolt in but you will need the all the electronics and the wiring harness including the Powertrain Control Module/computer (PCM) to make it work. You will greatly increase the Horse power of the Grand Marquis.

Can not find witch harness fuel pump fuse is in


fuel pump is protected by a relay. see owner manual for location.

PCM power relay powers up PCM. PCM then powers up fuel pump through fuel pump relay.

Also, check to be sure inertia switch is not tripped. In trunk. look for label or look in owner manual for info.

1989 mercury grand marquis


pull each fuse one at a time and check them , or use a multi tester to check them to find the bad one. if you are going to pull and visually inspect each one individually be sure to put them back in the same hole they came out of.
