I am having trouble starting my 2000 Saab 9-5 in hot weather.
The temperature has been in the 90's the last few days. After
I have driven the car for a while in the heat, turned the car
off and then immediately tried to restart, the car will not
start. (engine cranks normally). If I wait about an hour the
car will then start normally. I took my car into my mechanic
on a cool morning, the car started normally and he did not
find any problems.
Ideas? |

A "vapor lock" is cause of most trouble these days. I sent my car to
service, but the mechanic said it was "seized" and had a "vapor lock".
My computer also "seized" because it had a "vapor lock". I didn't fell
well, so I went to my doctor, he told me that my head had "seized" and
that I probably suffered a "vapor lock". >> Stay informed about: Problem starting in hot weather |

When I had a problem, it took quite some time, but the problem
was found to be a failed rear fuel pump. This gives all the
symptoms of vapor locking and is hard to diagnose. I've had
two rear pump failures over the years on my C900. >> Stay informed about: Problem starting in hot weather |

Possible temp sensor failure for the ECU and it's trying to do a rich
cold start when hot.

Hi,
It sounds like you need a new 'crank case speed censor', I had the
same problem as you and this cured it.
Saab charged me £160.00

It took my car back to my mechanic again. This time he replaced
the 'crank case speed sensor' and so far the car is working fine.
Since my mechanic was not sure if this repair will fix the problem,
he will not charge me anything until I have driven the car for a
few weeks without any further problems. >> Stay informed about: Problem starting in hot weather |

Stick with that mechanic ! There's few that good.
My local guys aren't bad either. And they always remember me when I drop
in - I like that.

An update. Replacing the sensor fixed the problem. >> Stay informed about: Problem starting in hot weather |
