Have had no problems in the past. Today I went out to start my car this morning and it is cranking then starts for a few seconds then shuts right off. Do you have any information that can help me out?

Hi and thanks for using 2CarPros.com.

There are many things that can cause this. Ignition components, fuel system components, sensors and so on can cause it. Take a look through this link. It describes common causes and how to check.

See if anything helps in the link. To be honest, based on your description, it sounds like a low fuel pressure issue. With that being said, I suggest checking fuel pressure to the engine. Here is a link showing in general how it is done:

Here are the directions specific to your vehicle for testing. You will need a fuel pressure gauge. I realize most people do not have one, but most times, most parts stores will lend or rent one to you. The attached picture correlates with these directions.

COMPONENT TESTS AND GENERAL DIAGNOSTICS
Fuel Pressure Test

Special Tools Required
- Fuel pressure gauge 07406-004000A
- Fuel pressure gauge attachment set 07AAJ-S6MA150

1. Relieve the fuel pressure.

(see pic 1)

2. Disconnect the quick-connect fitting (A). Attach the fuel pressure gauge set and fuel pressure gauge.
3. Start the engine, and let it idle.
- If the engine starts, go to step 5.
- If the engine does not start, go to step 4.

4. Check to see if the fuel pump is running: listen to the fuel fill port with the fuel fill cap removed. The fuel pump should run for 2 seconds when the ignition switch is first turned on.
- If the pump runs, go to step 5.
- If the pump does not run, do the fuel pump circuit troubleshooting.

5. Read the pressure gauge. The pressure should be 270-320 kPa (2.8-3.3 kgf/sq.cm, 40-47 psi)
- If the pressure is OK, the test is complete.
- If the pressure is out of specification, replace the fuel pressure regulator and the fuel filter, then recheck the fuel pressure.
