Run your tests before you start buying your parts. verify that your fuel pressure is acceptable. a defective fuel pressure reg., clogged fuel filter, tired fuel pump, fuel injector, loose or damaged wiring to the injector or coil, maybe water in the gas or too much fuel cleaner/additive.

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.
