About a month ago my passport just all of a sudden stalled out and has not been the same since. When it does start it runs awsome and I can pump the gas and the RPMS go up and down with ease then all of a sudden dies there is no life in it at all. When I try to restart some times is will restart and run for about 5 sec, other times it will not restart at all for a long period of time. The CEL has never came on so I dont have any codes to go off for a repair, plus I had the batterie off for some time to charge it completly full so I am sure the codes are gone by now. I have tried this on warm and cold days and there is no difference.
I have tried everything I can think of-
1 cleaned throttle body with air intake cleaner not carb cleaner
including the EGR, IAC and other part connected
2 checked fuel pressure its good
3 had gaskets replace about 6 months ago when the water pump went out.
time belt replaced too
4 on the last take of gas I had put injector cleaner in with the gas
5 batt is new
6 alt has been rebuilt tested great
7 gounds checked and replaced all around the engine that I could find.

Any one with information please help as I am at a loss and dont want to sink money into sensors that may or may not be bad. My best guess at this point is the IAC or the fuel pressure regulater.

It sounds like a bad fuel pump, even though you checked it. Do me a favor, when it dies and won't restart, check to see if you are getting spark and proper fuel pressure to the engine. If you have both, check to make sure the injectors are getting power.

Let me know what you find.

Well I got the new regulater in at lunch time however, did not get a chance to start it because I ripped a hole in the hose that was in front of the regulater and didnt have any time to go get one before going back to work. So tomorrow I will finish the job.

So I got the hose repaired and nothing. The car will not even start now at all. I only installed a new fuel pressure regulater. So does this mean that mu pump is bad?

All pressure areas were checked.

Tried to start at lunch today and it started for about 3 sec then died. Started again and went for 5 sec. Tried a 3rd time and hit the gas once RPM went up and then died.

I am thinkinging that I damaged the IAC or EGR.
First time I cleaned them I used cheap carb cleaner.
I also had no clue and used a metal piece to scrape it.
Second time I cleaned them I used intake cleaner.

Even if they are bad or damaged, I would think you could keep it running with your foot on the gas. Since you have good fuel pressure and good spark to the plugs, the only thing left is a problem with the injectors. Have you checked to make sure they are getting power? Also, if you use starting fluid, can you keep the engine running?

I have not tried starting fluid to keep it running.
Also have not checked the injectors.

I will try both this week sometime once it warms up a little. Today is a very cold day here in SD. Snow/Wind and all that good stuff!

Let me know what you find. As far as the snow, wind. We get it here in PA too; however, it isn't nearly as bad as you get it. The older I get, the more I hate it. Lol

OK new up date.

Today at lunch I started it and just kept on the gas pumping the RPMS between 3and 5. Lots of smoke grayish in color. Once it was warmed up and the smoke cleared I decided to try to drive a little and it went great. I then tried to really give it gas to excell at a faster speed and then when I slammed the brakes it died. It would not restart on its own so I pum ped the gas while turning the key and poof it started. Drove again for a few min then slamed on the braked and died again. Pumped the gas again and it started.

So I got it back to where it was parked and let it idle for some time and it idled funny. It would idle fine for 5-7 seconds then spudder a little it did this over and over.

I can't remember if I asked, but have you checked for vacuum leaks? What you described either sounds like a leak or a bad idle air control valve.

After all the things I have read on what it could be this one most often pops up.(IAC). I just dont understand how this one part would cause this much trouble especially when I do get it going and keep it going but this part still manages to make it stall out. Maybe its the name of the part?HMM.

Well I am going to order one tday and it should be in tomorrow. I will get it replace and post a reply.
I was hopeing that I was not going to have to put anymore money into this vehcicle and it would just magicly fix itself but it appears that this will not happen. This car has lasted this long with minimal amount of effort and money for repairs so I guess a couple hundred isnt that bad.

On a vehicle with fuel injection, the only thing that goes through the throttle body is air. On newer cars, the throttle plate closes completely. Therefore, the IAC opens the throttle plate to allow enough air to get to the engine so it stays running when your foot is off the gas.

The only thing it does is maintain the idle speed. Also, I hope you're not paying a couple hundred dollars for an IAC. I just looked it up on Auto Zone's website and it is 44.99. Let me know if you are paying a lot more than that. I was thinking it should be under 50.00.

I said a couple hundred for the repiars I have done.
IMG=250ish
water pump
timing belt.
And some otheres. So a couple hundred was just kind of a guess but not a real good one. And Oriley has it for $52 but a 10% military discount
