If you are certain it is low fuel pressure and you've changed the pump and filter the next thing would be the fuel pressure regulator. Also check to make sure none of the fuel lines are crushed closed.
You should check to see if you are getting spark at the wires,and fuel pressure first.
Loose or corroded connections or the battery has a dead cell and will not accept a charge and must be replaced.
The alternator is not charging the battery, therefore, the coil is getting it's charge only from the battery.
Think fuel filter. If that hasn't been replaced, do that first....inexpensive, but even if this ISN'T the problem, it still needs to be replaced periodically! If replacing the filter doesn't help, you should consider taking it to a garage and getting your fuel-pressure checked. If the pressure is low (and you've replaced the filter!), then your problem is the fuel pump. If I were a betting man.....fuel filter.
You need to get the battery in the game cartridge replaced. Most gamestops will do it for you.
you may have a bad battery or a bad voltage regulator
my guess from what you said is that either the battery or alt. is getting weak battery and alternater replaced less than 4000 miles
The reason a Lincoln Town Car might not start after the intake manifold was replaced could be that the MAP (Manifold Absolute Pressure) sensor was not installed properly after the manifold was replaced. The computer might also need to be reset.
This particular battery is advertised as being very long-lived. If you are having problems getting it to hold a charge, it may be faulty and need to be replaced.
the starter isn't getting power or the battery is dead. do some tracing of the power and see where it isn't getting juice
You may want to check the fuel filter. these cars also have a fuel pump relay, I have the same problem with my car. have you gotten yours fixed yet? I'm just getting started on mine.
I would definitely change the gas and probably the oil first. Check for spark and fuel getting to the cylinders.
