No, the pump doesn't need removed. On the fuel rail (where the injectors are), there is a service port. That is where you connect a fuel pressure gauge to check pressure. Here is a link that shows and explains how it is done:
https://www.2carpros.com/articles/how-to-check-fuel-system-pressure-and-regulator
The link discusses a regulator being disconnected. That can't be done on your vehicle. We just need to know how much pressure is at the fuel rail. Here are the manufacturer's specs:
2011 Chevrolet Malibu L4-2.4L
Pressure, Vacuum and Temperature
Vehicle Powertrain Management Fuel Delivery and Air Induction Fuel Pump Fuel Pressure Specifications Pressure, Vacuum and Temperature
Ignition ON, engine OFF .................... 345-414 kPa (50-60 psi)
If you need a fuel pressure gauge, most parts stores will lend/rent one to you.
Let me know what you find.

Welcome back:
That is surely the cause of the cyl 4 misfire. That isn't enough compression to fire the cylinder.
I attached a pic below. It is parts and labor for a head gasket replacement. The labor listed is for removing and replacing the head.
Here are the directions for replacing a head gasket. Keep in mind, it could be a valve issue or something different.

For equivalent regional tools, refer to Special Tools (See: Engine > Electrical / Mechanical Repair > Special Tools).
Pic 2
1. Remove the cylinder head to the block bolts in sequence.
Discard the bolts.
Pic 3
Caution: In order to prevent damage to the valves and injectors during cylinder head removal, set the cylinder head on blocks.
2. Remove the cylinder head (1).
3. Remove the cylinder head gasket (2).
4. Clean all of the gasket surfaces.
5. Use the following procedures when cleaning the cylinder head and cylinder block surfaces:
* Use a razor blade gasket scraper to clean the cylinder head and cylinder block gasket surfaces. Do not scratch or gouge any surface.
Note: Do not use any other method or technique to clean these gasket surfaces.
* Use a new razor blade for each cylinder head and cylinder block.
Note: Be careful not to gouge or scratch the gasket surfaces. Do not gouge or scrape the combustion chamber surfaces. The feel of the gasket surface is important, not the appearance. There will be indentations from the gasket left in the cylinder head after all of the gasket material is removed. These small indentations will be filled in by the new gasket.
* Hold the razor blade as parallel to the gasket surface as possible.
Note: Do not use a tap to clean the cylinder head bolt holes.
6. Clean the old sealer/lube and dirt from the bolt holes.
7. Clean the bolt holes with a nylon bristle brush.
Warning
Wear safety glasses to avoid injury when using compressed air or any cleaning solvent. Bodily injury may occur if fumes are inhaled or if skin is exposed to chemicals.
8. When cleaning the cylinder head bolt holes use a suitable commercial spray liquid solvent and compressed air from an extended-tip blow gun to reach the bottom of the holes.
9. Remove any broken long cylinder head bolts using the EN-38188 - extractor kit.

30. Inspect the timing chain tensioner seal for damage. If damaged, replace the seal.
31. Inspect to ensure all dirt and debris is removed from the timing chain tensioner threaded hole in the cylinder head.
Note: Ensure the timing chain tensioner seal is centered throughout the torque procedure to eliminate the possibility of an oil leak.
32. Install the timing chain tensioner assembly. Tighten the timing chain tensioner to 75 Nm (55 lb ft).
33. The timing chain tensioner is released by compressing it 2 mm (0.079 in), which will release the locking mechanism in the ratchet. To release the timing chain tensioner, use a suitable tool with a rubber tip on the end. Feed the tool down through the cam drive chest to rest on the cam chain. Then give a sharp jolt diagonally downwards to release the tensioner.

I know that is a lot of work, but figured I would add it in case you wanted to do it yourself.
Let me know if you have questions and how things turn out.
Take care,
