2003 Marauder, had it transported from Florida to Texas. Started right up to drive off the transport. Pulled over to the curb and killed it. Went back 5 minutes later to drive it home. Wouldn't fire at all. Hasn't started since. It's almost like a theft device or something has engaged and has shut off the ignition. Do these cars have such a thing on them.

Does it try to start, as turn over with starter engaged but won't "fire up". Or do You turn the key and nothing happens at all?

Try resetting the fuel inertia switch located in the trunk of the car.

Cranks and cranks but won't fire. Already checked the inertia switch. This car has a Rienhart supercharger setup on it.

If the car is using a plug in computer chip, make sure it's seated.
Check all fuses
can you hear the fuel pump come on when you turn the key on, try removing the gas cap and have someone listen

Update, decided to change fuel pump. Found out it has two 250 Walbros in it. Went back with two 340s. Got everything back in and went to try it and still only a drip at the fuel filter.

Don't know your setup but one lesson I learned long ago with Fords when they went over to the EEC management system is that a marginal battery will engage the starter but may not provide enough power for the EEC to operate. Often starts as an intermittent problem. Have you charged and load tested the battery yet?

Post 5. The contacts need to be sterile clean as well as fully seated. The copper contacts need to be cleaned back to a shine from time to time. I learned this with my old chip years ago.

I still run that black 300a with the chip, it was Kelly tag alongs car.. ... It resides in my mothers garage as she drives it about twice a year, and my dad and i use it for business trips and trips to Florida, Texas Oklahoma Arkansas KY MI man weve been everywhere man... Such a nice car too, i would do a tune in it, but damn thing knocks down 4 cyl gas mileage on the highway, hate to make changes to it and get the same effect....
OP- your fuel pump driver module, you can bypass it with 12 volts (pulse by hand) and get the car running. I had to do the same on my car to get it into the garage.... Does the car have enough gas in it too? I bet the module went bad driving 2 pumps, you can wire in twin drivers, i sell them on ebay for less than 30 each. https://www.ebay.com/itm/2003-2004-Mercury-Marauder-Marquis-Fuel-Pump-Driver-Module-FORD-3W1F-9D372-AB/302857242050?hash=item4683b2c5 c2:g:nIgAAOSwGK9bgE~K:sc:USPSF irstClass!64055!US!-1
