In the fuel line on the rear of the intake manifold, there is a bleeder valve with a black cap on it. Remove the cap and depress the valve while the key is on. BE CAREFUL if the fuel pump is operating correctly fuel will spray out. If there's no fuel pressure, then the fuel pump is bad.

Occasionally, about every 6 to 8 times tried, the engine will turn but not start. If I turn the key off for about 3 seconds, it usually starts within a few turns. Do you know what can cause this?


A year, make, model, and engine size would help but I will through this at you.

Instead of just trying to start the car turn the key to the run position and wait 3 seconds. Turn the key off and immediately turn the key back to the run position and wait another 3 seconds. Turn the key off then try to start. Do this every time you try to start the car. If you symptom never occurs when you start the vehicle like this than I would suggest taking a closer look at the fuel system.

Reset change oil light on a 2001 Saturn l300


I don't know the year of the vehicle so I'll give you 2 possible ways to reset it.

2004-2005

Turn the ignition to run (one position before starting engine).
Immediately after Step 1 press and release the gas pedal 3 times within 5 seconds. If the Change Engine Oil light is flashing, the system is reset. The light will flash for up to 30 seconds or until the ignition is turned off. If the light comes on again and stays on for 30 seconds at the next engine start, it did not reset. You will need to reset the system again.
Turn the ignition off and then start the engine to verify the indicator has been reset.





Turn the key to run, but don't start the car. Open up the underhood fuse box (move the coolant line out of the clips for easier access). In the fuse box is a button labeled "OIL-R". Hold it down for five seconds. The "change oil soon" light should flash for about 30 seconds or so. That means it's reset.

How to rekey a pontiac sunfire 2004


Im assuming you are refering to the anti theft security key relearn process.

1. Perform a security system relearn.
2. Let the vehicle sit for more than 10 minutes with the key off.
3. Attempt to start the engine, leave the key in the run position monitoring the security system indicator.
4. After 10 minutes, the security indicator will change state.
5. Turn the key off and wait 10 seconds.
6. Attempt to start the engine. If the engine stalls, wait another 10 minutes with the key on.
7. After the second 10 minute timer has expired, turn the key off for 10 seconds.
8. Attempt to start the engine. If the engine stalls, wait another 10 minutes with the key on.
9. After the 3rd 10 minute timer has expired, shut the key off for 10 seconds.
10. The security system will relearn on the 4th starting attempt and the engine should start and run.

If that doesnt work, look into this link http://vatspasslockpasskeysecurityhelp.yolasite.com/

Programing a key fob


1. Perform a security system relearn.
2. Let the vehicle sit for more than 10 minutes with the key off.
3. Attempt to start the engine, leave the key in the run position monitoring the security system indicator.
4. After 10 minutes, the security indicator will change state.
5. Turn the key off and wait 10 seconds.
6. Attempt to start the engine. If the engine stalls, wait another 10 minutes with the key on.
7. After the second 10 minute timer has expired, turn the key off for 10 seconds.
8. Attempt to start the engine. If the engine stalls, wait another 10 minutes with the key on.
9. After the 3rd 10 minute timer has expired, shut the key off for 10 seconds.
10. The security system will relearn on the 4th starting attempt and the engine should start and run.
If this doesnt work, you may have a failure in your system. If the security light is on, and the reprogram doesnt work, you might want to look into bypassing that antitheft system.

Starting problems


Dirty fuel filter or faulty fuel pressure check valve which is located on your fuel pump sending unit. Try this test, turn the ignition on for 10 seconds (engine not running) then turn it off for 5 seconds and turn it on again then try to start the engine after 10 seconds. This will re-pressurize the fuel lines to start the engine, the fuel injectors need 62-65PSI to have them start the engine. Anything less then that and you'll have starting problem.
If it start's right up, then your ether have a fuel pressure check valve gone bad or a fuel leak at your fuel pressure regulator which is also common, but if your engine is still running 100% then i'll lean towards check valve or dirty fuel filter.

Start with the simple and replace the fuel filter, a dirty fuel filter will cause fuel restriction that may just be enough to the fuel pressure below 62PSI upon cold starts and a dirty fuel filter will cause the fuel pump to fail early in it's life.
Thank you for using Fixya and goos luck.

Hard to start after it sits u have to keep cranking for at least 30 t0 45 sec


When you turn on the key the fuel pump relay causes the pump to run for one second to bring the fuel manifold presure up. If the vehicle has 'sat' for a long time, this one second is not long enough and so the engine is struggling to get enough fuel to fire. Try turning the key on and off every couple of seconds for about a minute, then turn the key to the start position. The engine should now start. Do not touch any controls such as the throttle, the computer will take care of all this.

Takes multiple times to start


I think you have a faling fuel pump or a bad pressure regulator allowing fuel pressure to bleed down when the engine is off.
Try this test - When you start the car for the first time of the day, turn the key to "ON", wait a few seconds, turn the key off. Wait about 15 seconds, turn the key to "ON" again, wait a few seconds. Then wait one final time for 1 seconds and try starting the car. If it starts right away, that means fule pressure is bleeding of due to a bad check vavle int he fuel pump, a bad fuel pump or a bad pressure regulator.

The reason for the procedure is because when you turn the key to "ON", the fuel pump runs for 2 seconds and then shuts off if the engine is not running. The 15 seconds wait is for the power and fuel pump relay to cycle off before it will run the pump again.

Let us know how the test comes out. The fuel pump is in the fuel tank and hums when it is running.
