Chevy Venture Starting/Stalling/Idle Issues

Our 2000 Venture died yesterday. I tried to start it, it clicked and made a funny noise in the dash area. So, we replaced the battery and it started right up. Left it sit in garage overnight. Started it this morning. Left it sit about 10 minutes and tried to start it again and nothing started! Only that funny noise up in the dash area. Not a clicking. Something sounding like it was running...can't explain noise. Any ideas where to go from here?? Thanks so much.

2000 Venture V/6 120,000 miles , bought used, ran great for year , now suddenly won't turn over . New battery, ignition checks out , daytime running lights even go off when key turned to start like they're supposed to Red light is on the radio which hints of security issues
Engine starts immediately when relay "jumped" ,runs for two seconds and dies.All dash lights gages and power accessaries working. Replaced starter and fuel pump relays just in case . Have normal wiring diagrams but dealer won't
release any info to bypass the security curcuits.
(can't really blame them)
Don't really want to tow van to the dealer, when I have my
own shop and tools to do the work, I'm a marine mechanic.
Hoping someone out there has had similar problem and has some info to get this van back on the road.

As for the #5 fan setting - I think its a separate issue - blower resistor going bad perhaps - cheap part about $ 20, its located behind the blower on the passenger side front. Easy repair, very common failure on the Venture. The flickering seems to be common on the Venture and usually is cured by a new alternator - it probably flickers more because the fan running on high speed is a pretty big electrical draw.
Just some things to check right off the bat - post more details and hopefully I can help you further.

Actually my AC is already shot. We just don't turn it on.Compressor clicking when we turn the ac button on. I have not decided if I want to spend that much money yet. The sound I am hearing when I turn the fan on is coming from the engine itself. Is there a vacuum line connected to the HVAC that could be causing this?
Are you sure the click isn't coming from the compressor? On some cars, the compressor kicks on when the selector is in the defrost setting, not sure if this is the case in the Venture, if so, then there's an electrical connector on the compressor that you could unplug...will have to check on the wife's (2000 as well) when I get home, maybe that's the click or does it not matter which position the vents are in? Is it the same click? Let me know...I'll have to admit that you may have me stumped....I've never known an alternator to make a click...usually a grinding or metal on metal scraping sound...I just can't think of anything that would click in an engine when you turn on the fan. With the hood up can you get a general idea of the direction of the click?
There is a loud knocking when first started that lightens after running for awhile but is still there. The oil is fine, no lights come on, seems to run fine. Any ideas anyone? Never had a moments problem with this van in the four years we've had it. Only has 97xxx miles and has had the oil changed religously.
Does it eventually go away?? All of the 3.4 V6 in the Ventures make a metallic tapping sound when they first start which goes away in a few minutes. Its nothing to worry about, the lifters in these motors are pretty noisy at startup. I think if you keep up the maintenance the way you've been doing you should have no problems.
get a digital multimeter, check the resistance on the ignition modules (located in back on top) between the two towers on each (towers meaning where the spark plug wires connect to) the resistance should be 5000-7000 ohms - if its above or below, you've got a bad ignition coil...and make sure the posts are clean
Run a bottle of fuel injector cleaner through it (Techron recommended)
Get a can of MAF sensor cleaner and follow the instructions.
Just a couple of things I would try right off the bat...
No codes at all? No check engine light? Interesting...
You may also want to check the connection on your oxygen sensor (the one up by the motor) maybe something disturbed there. Only problem is, if the O2 sensor was disturbed, it should give you a check engine light. Check anyway...
Possible, but not necessarily probable. I'm not really experienced with the Intrepid but try this: Disconnect the negative terminal from the battery for 30 minutes and then hook it back up. That should be enough to clear the code if there is one. With the OBD2 the computer checks a bunch of stuff at different intervals and under different driving conditions. It may have set the code just to say that it performed a test and the vehicle didn't pass this time so it lit the light and is waiting for the proper conditions to try it again. If it passes, the light will go out and it will store a code that will say what the problem was but will not make the light illuminate.
If it still doesn't clear - Autozone & many other parts stores will check the codes for free. Get the codes read and post them here, maybe we can figure it out.
See if you can get the codes and repost....
The 3.4 V6 is a quirky engine no matter what vehicle its installed in, not just the Venture. I really think a lot of mechanics don't even know what to do when the check engine light comes on other than read the codes and start replacing parts. Its an interesting marriage of an engine originally designed in the late 70s and modern day electronics. Cool thing about them though - the same things go wrong with all of them so chances are you're not the 1st to have any particular problem and the fixes are usually not too difficult (at least most of them anyway)
Boy do I miss the days when you could read the check engine light with a paperclip.
not sure how they figured out the egr valve but it worked..i have gone through so much sh*t with that van..2 intake manifold gaskets..one costing me an engine...and the list goes on
All the best,
John
I had the misfire code as well - got rid of it by:
1. Cleaning the MAF sensor - use cleaner designed specifically for the MAF and follow the directions on the can
2. Replace the PCV valve
Also, try this - get a digital multimeter, check the resistance on the ignition modules (located in back on top) between the two towers on each (towers meaning where the spark plug wires connect to) the resistance should be 5000-7000 ohms - if its above or below, you've got a bad ignition coil...and make sure the posts are clean.
Someone else here also had an issue with the EGR valve being plugged up with carbon - you might want to pop it off and take a look...the pintle in the middle should move freely up and down (its spring loaded IIRC) - if not, try cleaning it and reinstalling, carb cleaner works pretty good, also know people who use Marvel Mystery oil to break up the carbon to make it easier to clean.
You've already done the other stuff I would suggest. Good luck
When I start up it works great but if the engine become hot if I shot off the engine and I try tot start again it didn't start at all. I have to wait to cool down the engine almost one hour and after that to try again. Everything works.
I was to the mechanic I change the starter and the ignition relay but the problem is still come.
Do you have any idea? Any help will be great appreciated.
Thanks a lot.
My Chevy starts very well when is cold but it did not start when is hot. I mean I have no power for the starter so the engine did not turn so it is not the CPS the problem. I change the starter and ignition relay and I have no idea what could be the problem. All the display indicators seem to be O.K. No alarm.
Why I don't have power to the starter when the engine is hot? Its start right away when the engine is cold.
Thank you for yours answers.
My fuel relay was this way. Hopefully this is it.
It could be just a wire but onestly I don't thing its a wire problem.
3.4L
2 year old battery
Sometimes when we try to start it, dash goes crazy, nothing happens under the hood. Return key to "off" position and try again and it starts just fine.
Any ideas why?
Loose wire to starter connection as well as corrosion in between the battery cable bolts and the connection cover over the bolts. Even though I had cleaned the wall of the battery and the bolt threads, there was poor continuity from bolt to cable...
Good Luck :shades:
