Yesterday morning our S70 wouldn't start. The dealership took a look and said they couldn't find anything wrong with it and said it was flooded. I disagree with them. When you turn the ignition like you do everyday you expect the car to start. Yesterday morning it did not, on the first try and several attempts after that. I did allow time to pass between the attempts incase there was a flooding problem. The dealership said that if it happens again then I should let the car sit and then press all the way down on the gas pedal and turn the ignition until the car starts. I don't believe this is a satisfactory response, and that you should not have to do this to start a 2000 vehicle. Maybe if this was a '74, but not a newer car.

Anyways... I just wanted to see if there was anyone else that has had this problem, and if they found out what the cause was.

We have had several other problems with this car, but I won't go into them on the board.

Thanks!

We had a bad fuel pump in the gas tank that caused they same type of problems you are looking at. I hope that's not your problem -- it cost $1600 to replace the old one

Thank you all for your helpful information.
I have a 2000 s70 awd volvo and last year I had a problem starting my car.
They gave me a new starter which did not help the problem but when they gave me a new igition and switch that seemed to correct the issue for a year.
Now I am having an trouble starting it, at times nothing will happen when I try to start the car and sometimes it starts but then in a few mintues it stalls. The problem is sporadic and I have taken it to 2 menchanics who say the car start fine for them.
Thank you for any response.

You do realize that you responded to a 10 year old post?

I suggest you start a new thread...:)

I have had this problem intermitintly on our 2000 S70 GLT. Most of the time it
occurs after long driving periods. So far repeted slowly cycling of the key off and back on (after realizing it was not going to start) without going to the start position then trying to start the car has worked. This has happened approx six times in what is now 45,000 + miles. If any one finds a cure for sure I would appreciate a message.

I eventually had to send the car to the volvo dealer who figured out that the problem was a faulty ring antenna which picks up the key code when you start your vehicle. The intermittened problem cause the immobilization feature to kick in and the car would not start. They changed it out and so far so good.
I must compliment my Volvo service department (Duplessis in Baton Rouge) and its manager Rusty for their work. In/Out in 45 minutes with a washed and vacuumed car on a very busy day for them. The best part was it was covered under the warranty (FREE).

My wife had the same starting problem with our 2000 S70 GLT SE. Among the various problems pointed out in this and other forums, it could simply be that you have both the service key and master key on the same key chain and that the car is getting confused and the immobilization feature is kicking in (page 44 of the manual).
While researching this, I found another gem which may also fix the problem. There is a way to reset the Service Light using the odometer reset button and an ignition key sequence(99 and newer models). Press the odometer button with the key in the off (O) position. Turn the key to the II position and wait for the Service Light to Flash. After it starts flashing, let go of the odometer switch and then turn the key to the OFF position.
This must reset something in the computer because my S70 which did not start all morning, instantly started after I finished this process. An added benefit is that you can now change your own oil.

HAVE SAME PROBLEM WITH 850 .STILL WORKING ON IT.BOGDAN.

The newer Volvos have anti-theft chip embedded into the key and a receiver to interact with it in the car. Sometimes this system gets confused and decides to lock you out like a theif. It cuts both the fuel and the ignition. Just another area of problems to ponder...


Good luck.

P.S. As far as I understand the valvetrain system has been redesigned elimintating the possibility of a "Lawnmower Syndrome".

I spoke too soon about my fuel being the problem....My 2000 S70 is in the shop as I speak, due to a now re-occurring warm-start problem. After driving for an extended time, the engine being fully warm, and stopping the engine for 5 to 20 minutes, it doesn't want to restart. This morning, I stopped to get a cup of coffee, came out of the store, and it cranked several seconds. Recranked, and finally it started, did the initial rev-up and died. Did this twice. Finally it caught and ran normally. Drove to to the dealer, and hopefully, they will find the problem. It just had it's 30,000 mile service two weeks ago, BTW. Will post what the found...if they solve it this visit.

They "Think" they have the problem solved. The word I got was that they think there was a bad connection to the ECU main computer chip...I guess time will tell for sure...
Ed

The dealer wants to get it back next week, to replace the wiring harness to the ECU. Said something about a corrosion problem in the female socket that connects to the unit. Wants to keep the car overnight to thoroughly check it out, to be sure it causes no further problems. Starts OK now from whatever cleaning they did....

If you were using really cheap gas, or had very little gas and condensation mixed with the remaining, it could cause very hard starting. Try filling up with really good gas if you havent already. Hopefully its something as simple as that. Good luck.

I had two mornings when it was hard to start. I had been buying 92 octane fuel at Costco, and had been noticing as the car warmed up, there was an unusually high amount of steam in the exhaust. I since put in two tanks of Texaco gas, and no more start hesitation, and the exhaust looks normal again.

There is a flooding problem often called the "Lawnmower Syndrome".
It occurs if you start the car for a few seconds (to back it
out of the garage to get at the lawn mower) and then turn off the
car without letting it warn up a bit.

Any chance something like that occured?

Now, a 2000 should not have this problem. My wife's 1995 850 has
had this problem twice (but now we always run it for 1 minute).
I have a 98 S70 and have never had this problem. The 98 starts
noticibly easier then the 95, too.

I suppose flooding could be caused by a leaky fuel injector or
valves that are not closing (seated) all the way. I think the
dealer needs to take a closer look.

to sweep the floor, so it didn't run for very long on Sunday, but we did drive it on Saturday. If this is what caused the problem it still doesn't seem normal. I didn't expect to have this many problems with a fairly new car.

Thanks for your advice!
