2000 olds intrigue hard start by jmerrittok

I have 2000 old intrigue with hard start problem 69,500 miles on it. cranks and finally starts. seems to start in very cold weather 10 - 30 degrees. harder starting in warmer weather above 30. took to mechanic. Not showing any code. he replaced fuel filter, added fuel cleaner. ran out the ethanol fuel and replaced with higher octane(middle grade) fuel. seemed to start better. went back to lower grade non ethanol. still having hard start. it will start on 3rd try. the engine revs to 2400 rpm and settles down to normal idle. mechanic says that the fuel pressure is running around 31 psi. after starting engine runs too well to have too much wrong with it. it is consistantly hard in warmer weather than in colder weather. saw a posting #25 of 67 Re: 2000 Intrigue starting issues [dtownfb] that had very simmilar issues but did no see conclusion of results. please help!

My issue ended up being a bad ignition switch (re-use the tumblers). My problem started in colder weather and by June I needed 5-10 tries to start the car. I also experienced stalling while driving and had the "security" light flash a few times. It took a while for me to diagnose the problem since the symptoms of a bad ignition switch can mimic fuel related problems like a bad fuel pressure regulator or a bad fuel pump. Also I simply didn't have the tools (or comfort level) to check the fuel pressure regulator.
 
If the "check engine" light doesn't come on and you are experiencing hard starting, you are basically dealing with either a bad ignition switch or the fuel pressure regulator. A bad crankshaft sensor or camshaft sensor will also cause hard starting but will throw a code. Neither the fuel pressure regulator or ignition switch will throw a code. This applies to the 3.5L engine.
 
I replaced the ignition switch myself using an aftermarket brand. I posted the directions here on Edmunds'. A poster from another forum supplied the directions.

I've heard the fuel pressure regulator is not hard to replace and the part is not too expensive. If you are comfortable working on a car, you might want to try replacing the fuel pressure regulator and ignition switch yourself. A FPR costs about $60.
 
Hope this helps.

I have a 1999 Intrigue and sometimes when I turn the ignition to start the car, it starts like normal the the next second the rpms drop below 1000 and sometime the car even stalls. Also other tine the car wont even start on the first try. Im not sure what to do.

What engine do you have? Are there any "Check engine" lights on? Does the car stall while driving? Or does it stall after being driven for a while? Any other driveability issues?

I have the 3.5 liter, and nope the check engine light doesn't come on. It hasn't ever stalled when i has driving, only when starting. Other than that it runs great

That narrows it down to the fuel pressure regulator or ignition switch.

If you search the forum, you will find many cases of faulty ignition switches on Intrigues causing stalling and starting issues. When one of my Intrigues or my brother's two Intrigues has stalling issues, that will be the first part we replace.

Starting/Stalling of 98 Intrigue by nyitrain07

I currently own a 98 intrigue, with 105k and have owned for nine months. In Dec. 08, the car would not start in cold weather, but it was covered in snow. It started the next day, but kept on stalling and once it got warm it would no stay running. My father is a mechanic and we have replaced plenty of parts and problem is still not fixed. We have replaced spark plugs, boots, coils, fuel filter and pump, ignition control module, fuel regulator, crank sensor and new intake. I have read it could be the ignition switch, but i have tried to wiggle the key and the stayed running when it wanted to run. Everywhere i look i only read about the 3.5 motor and not the 3.8,so i dont know where to look anymore. Could it be the computer, mass flow air sensor and cam sensor. The computer isn't giving us any codes and seems to work fine. I am sick of this car and just want the problem fixed. Any ideas please comment back.

I recently bought a 2000 intrigue 3.5l v6 gx model with 109,000 miles on it. I took it to autozone and had the battery and alternator tested and my alternator was only running at 55 amps so i replaced the alternator and had it tested it again and the amp output was 141. well now the battery is not being charged by alt. what gives? also i had the service engine soon indicator come on so i had that tested and was told it is the crankshaft position sensor. i am due to have that replace this weekend. any assistance from experienced intrigue owners would be greatly appreciated. i am ready to throw my hands up. but i read several post in this forum that this is a really good car so please any insight.
