    ok so ifigured this thing out... i changed the gas cap, and the evap purge valve(EVP). total cost was 45 and it took me about ten minutes to change both parts. i have good mechanical background but anyone can fix this problem. EVP is located on passenger side of intake manifold near the battery. it has one electrical plug and two hoses connected to it. disconnect battery first, then unplug the evap purge valve and disconnect hoses from it also. replace with new EPV, plug in sensor and hoses. reconnect the battery, check engine light will reset itself. start car and the check engine light should be gone and no more worries:)

You just need to go through a simple Idle Relearn Process.

The Idle Speed Control motor will cause the accelerator pedal to tap and the car will surge back and forth, actually acting like there is a lack of power during intial startup.


Whenever a battery is changed, went dead or the ECM computer is replaced.

In order to make the engine run normal again, you need to take the car through a relearn process. Otherwise the idle could be very slow or have a 30mph idle.

To enable it to relearn, here's what to do.

1) Disconnect the battery cable for 15 minutes, before hooking it back up.

2) (KOEO) Turn the Key On with Engine Off, just so the electronics are on, but without starting the engine and turn the climate control panel to off.

3) Push the off and warmer buttons on the climate control panel at the same time and hold for up to 5 seconds for the computer to go into diagnostics.

On the fuel panel screen it will display 888 then E52 and then 70.

When it gets to 7.0 shut off the key for 1 minute.

4) Repeat step 3, two more times.

5) Start the engine without pushing on the accelerator pedal and let it run for 18 minutes with the climate control panel off.

6) After 18 minutes put your foot on the brake and shift into drive and wait 1 minute.

7) Then turn on the a/c by pushing the auto button. It needs to be warmer than 60 degrees F so the compressor can engage. Wait 1 more minute.

8) Put the shifter back in park and turn the key off.

9) Wait 1 minute

10) Idle relearn is now complete and the engine should start and run correctly.

2005 cadillac cts wont start wont say anything.


Won't start how ? When you turn the key to the start position does the starter spin the engine ? Or not ? This would be a no crank - no start condition ! Or when you turn the key to start the starter spins over the engine but it doesn't start an run ? This is a crank - no start condition . Both have very different diagnostic testing procedures ! An what won't say anything ? Is there a car an padlock symbol lit on the instrument cluster ?

2004 cadillac cts wont crank at all, i turn the key and try to start it but it doesn't crank or do anything just the dashboard light come on and the engine light flickers then it wont release the key


I had something similar happen on my 2004 CTS. The car would not crank, and I recall the security light was on the dash. The key could be turned off, but not quite far enough to be removed.
The key can be removed by sticking a small pin or screw driver in a hole under the steering column... maybe 2 inches from the actual steering wheel. I recall there is a small cover or plug in the hole that needs to be removed.
You can let it sit and occasionally try to start it. My did start once more.
I ended up having it towed to the GM dealer and they replaced the ECM for about $500? That took care of it for a couple years, until I recently sold it.

Run fault codes check as it may be a failed cam/crank position sensor that will not allow it to start or some other faulty sensor that is the problem. Do not waste money until you know what you have to replace

93 saturn wont start unless you hold dowm gas pedal


Have you tried cycling the key a few(3-5) times, before cranking(and trying to start it?
What i mean is turn your key on, then off, and on, then off(3-5 times), and then turn the key back on, and try to crank/start the vehicle, See what that does!

If that works then you have a fuel leak somewhere.

if that DOES'NT work, fuel is leaking into your engine while it sits
(more than likely bad fuel injectors!)

Car wont start


THere is no gas in the fuel rail at the time gas is running out. WHen you fill the tank, it needs to pump for a while so fuel can fill up the rail then the Fuel distributor so it can build up pressure for the injectors to work properly. It need to continue cranking at least 2 minutes. However you don't want to run out the battery, so can just turn on the key to hear the sound of the fuel pump stops, then turn key off turn key on again. Repeat this for 6 times then start the engine. The reason for it is that every time the key is on it turns on the fuel pump to prime the line then turns pump off after a specific time, then it turns on again only when key is at ignition position. By doing this you help to pump gas into the fuel rail instead of the starter continue cranking draining down battery fast. Cheers.

You either have a bad solenoid on your starter OR a bad ignition switch as these are the only two things that can cause the symptom you describe... I lean to the solenoid first, RARELY does an ignition switch sieze up in the start position but it is a possibility. Several national chain parts stores can test the starter for you (GM starters have the starter solenoid mounted directly to the starter and you need to remove the starter to get to it, so you would take the whole unit in to test it... REMEMBER to disconnect the battery first!)
