Considering it's a mechanical pump driven off the camshaft, it's unlikely to be in the rear of the car. The location of the pump can be found by following the fuel line off the carburetor down to the side of the engine.
If the fuel filter has not already been replaced, that should be done before replacing the pump. The filter may be clogged with old gasoline deposits if the car has been sitting for a long time.

We have a 79 Mark V that refuses to start. The engine turns over, but just won't start. It has a new carburetor, new battery, & new ignition coil. Fuel goes into the carburetor just fine when turning over. Any suggestions on what the problem is? Thanks.

Does it have spark? If you take out a spark plug and lay it on the engine block, does it spark when you crank it? The coil might have been hooked up incorrectly; maybe the positive and negative are reversed, or the coil wire isn't seated properly. The distributor cap might have been jostled, etc.

Ignition switch?
Starter?
Ignition column interlock fully in park?
Battery cable clamps brushed, tightened and clean, and a good clean cable ground?

Uh, if any of those were at fault, the engine would not "turn over".
Instead, check for spark as suggested in the preceding comment.

It shuts down. I would check the list. Poor grounds and heat can also shut down vehicles.

I have a very clean 1979 Lincoln Town Coupe for sale; where would be the best place to advertise it?

Hey folks.
Looking for help with my 79 Town Car. Just had a full tune up, fluids, sending unit & everything I could think to get her running perfect again. For the most part it does, but after running or driving 20 or 30 minutes, she starts to hesitate & then shuts down. Called a mechanic to come get it, told him it's still doing it, & he got it back to the shop & it fired right up. He's been driving now without the problem reoccurring, so can't diagnose it. Anyone?.. not sure what next.

Yes, because this benefits others driving this year, make and model automobile in 2017. Plentiful today, which may benefit others with informative maintenance awareness.

Nope. Saying that a new coil "might" be defective is not very helpful. Not at all.

Oh really? Well it happened to me and it was a hair pulling experience. Even worse than tracing a parasitic electrical drain on a RV. Do not assume that a new (which is often a rebuilt/offshore remanufactured) part is always A-1. You are still totally going through tracing an issue when the secondary new part was not curing the existing problem. So hopefully this validates my earlier comment.

Totally agree with you on that one. Most if not all house brand (white box) replacement parts are made in China and are horrible quality. Years back the crank sensor went out on my Lincoln; I purchased the cheaper one and it failed a year later. After that I bought one from the Ford dealership and haven't had a problem since.

Yeah, a "rebuilt" ignition coil?
Haven't seen one of those in a while. Or, actually, ever.

I buy all my light bulbs now at the dealer vs ones that burn out rapidly from a well known aftermarket distributor. I also had rebuilt starters that failed new out of the box. I should say newly rebuilt as we have a real stickler on here with his take no prisoner approach in comments made. Even with validity in them.

Your mechanic should have the appropriate equipment to check the ignition control module on the side of the distributor (Fords). They get corroded inside after so many years and short out after they heat up.

My 1979 Mark V with only 26,000 original miles on it turns over but will not start.
I tried the ether in the carburetor trick to no avail.
I replaced the electronic module brain and still no spark.
Replaced the ignition coil and also a new distributor.

Do you have a 12-Volt test light?
If so, connect one end to the negative side of the ignition coil.
Connect the other end to the positive side of the coil.
Crank the engine.
Does the light blink or flash on and off?
If so, the pickup coil in the distributor is working, as is the ignition module. The problem is likely the coil.
If not, the pickup coil in the distributor or ignition is likely the problem.
Hope this gets you started.

Yep, probably a bad pump and lines. The pump is in the rear of the car if I recall correctly.
