I was driving normally and all of the sudden my rpm started dropping and my car like shut off and when I start it cranks but hesitates sometimes and when it starts I can't rev past 4,000 and when I rev it it to go in gear it shuts off.

Hi,

If the check engine light was staying on prior to this, first scan the computer for codes. Here is a quick video showing how it's done:

I realize most people don't own a scanner, but often times a parts store will lend or rent one to you.

Now, based on your description, I believe it is a fuel related issue. If there are no stored codes when scanning, lets start with fuel pressure.

Here is a link that shows in general how to check it:

Here are directions specific to your vehicle for testing. The pressure specifications are included in the directions. Also, the attached pic correlates with the directions.

1. Relieve fuel pressure.

2. Remove the service bolt on the fuel filter while holding the banjo bolt with another wrench. Attach the special tool.
3. Start the engine. Measure the fuel pressure with the engine idling and the vacuum hose of the fuel pressure regulator disconnected from the fuel pressure regulator and pinched. If the engine will not start, turn the ignition switch ON (II), wait for two seconds, turn it off, then back on again and read the fuel pressure.

Pressure should be: 260 - 310 kPa (2.7 - 3.2 kg/Sq.cm, 38 - 46 psi)

4. Reconnect vacuum hose to the fuel pressure regulator.

Pressure should be: 200 - 250 kPa (2.0 - 2.5 kg/Sq.cm, 28 - 36 psi)

If the fuel pressure is not as specified, first check the fuel pump. If the fuel pump is OK, check the following:
- If the fuel pressure is higher than specified, Inspect for:
- Pinched or clogged fuel return hose or line.
- Faulty fuel pressure regulator.
- If the fuel pressure is lower than specified, inspect for:
- Clogged fuel filter.
- Faulty fuel pressure regulator.
- Fuel line leakage.

Let me know what you find. Also, let me know if this has the vtec engine.

Take care,
