Save youself money and take it to a trusted automotive shop. I suspect you will replace every part you suspect is bad rather then testing and performing any troubleshooting

Really by the way you describe it you need to check the fuel pressure. There is a valve on the fuel rail for testing it. You will need a fuel pressure gauge. It should have 55 to 65 psi. It will not run on less than 50 psi. If you have less then it will be your pump. Good Luck

Perhaps it's a stuck carburetor float valve, bad fuel pump (if it has one) or clogged fuel filter.

You've already replaced most of the stuff I've guessed, unless perhaps the fuel pump is faulty or there's something partially clogging the fuel line. Maybe put a fuel system cleaner additive to the tank? Other thing is perhaps the coil.

My 1996 Pontiac Grand Am GT stick shift vehicle keeps dying. It will shake when the gauge gets to the 1 RPM spot and continue shaking for a little bit and then just die. I have replaced the oil but perhaps...

Wrong, it couldn't be the battery because the battery is basically used to keep track of the time and make sure your car starts, after it does the battery basically charges and runs like the radio etc. The fuel filter would be more likely, but my money's on the fuel pump itself. You might also have an engine coil firing out of order, which would cause the shaking and an occasional **** from the car.

-Get a tune up.
-Get a machine hooked up to your car by a mechanic (full systems check)
-Check the transmission fluid.
-Tell the mechanic that it's probably the fuel pump. The fuel pump starts going bad, and then your gas gauge starts fluctuating, and your engine starts struggling to get to higher RPM's because it can't **** fuel out of your tank fast enough.

All in all to get this baby back on the road at full force could run you 200 to around 500 dollars. Then depending on the mechanic the labor is more.

Tune up (100 bucks) transmission fluid change(20-50 bucks) Full systems check (50-80 bucks) fuel pump(150 bucks) then the labor for everything would be anywhere between 150-300.

Hope it helps.

Step 1

Check fuel pressure. If you have over 80,000 then just replace fuel pump and filter. Fuel pump is in the tank so run out as much gas as you can.

Step 2
Also do a tune up plugs , wires ect... if you haven't already.

Rust in ther filter means rust in the tank. There is a primary filter attached to the fuel pump inside the tank. Before you go further, replace that filter & wipe out the inside of the tank as well as you can.
Then check operation of pump and how it runs.
Good Luck

Engine will not that accelator pedal

I had the same problem. What it is, is low fuel presure at the fuel rail caused by either a bad/clogged fuel pump or a clogged fuel filter. You are supposed to have 33-37 psi at the rail and mine dropped as low as 16 psi. Mine was caused by a secondary fuel tank that was metal. the tank rusted inside and that rust ended up into my main tank. On long trips that rust would build up at the pump causing it to starve the engine of fuel. Ford quoted about 900 bucks to change out the pump.
I suggest buying a pump at somewhere like Napa and installing it yourself, making sure the tank is clear of debis. You can do this for under 200 bucks.
