Hello,

I bought a used 99 9-5 se about 8 months ago with 86k. Since I've had it I've had a few strange problems. One is that whenever I have less than 1/4 tank of gas, the car is hard to start (requiring me to crank for a few seconds). If I've got more that that I don't have a problem. I've replaced the DI cassette, spark plugs, fuel filter. I've run BG44k fuel injector cleaner through it. I've changed the air filter. Is it possible that my fuel pump is in need of replacement?

Also, my car sometimes stalls if I try to take off right after starting. This problem doesn't seem to be related to how much fuel I have, but I haven't been able to figure out what it is related to. Most of the time it is fine, it's just an occasional problem. Anyone have any ideas?

Thanks!

Hiya Dabbith, welcome to Saab Central ;)

Assuming your spark plugs are in good order I would first change the crank position sensor and see if that helps.

I had your problem too, I changed DI, throttle body, plugs, fuel filter and then the CPS (which was the only change that really helped), then one day she died on me again and I finally changed the fuel pump, not had a problem again ;)

Hi, in Singapore the distributor actually advise car owner to change fuel pump every 50k km milage interval...I was actually quite fustrated with them as I have never need to change the fuel pump in any of my 5 other cars that I owned in the past and some even with exceed 200k km milage..

Guess maybe it is the fuel pump that is faulty in your case...

cheers,

sam

Hi Finn,

I also cannot agree with that but when you drive into the Singapore distributor workshop for the 40k km major service the customer service will advice you to change the fuel pump in the next 10k servicing...I heard it myself and have some fight with that guy...finally I went to another private saab specialist for my future servicing...

after about another 15k km, my fuel pump really give way...but not the pump, it is that plastic catch on top of the pump that is holding the pipe in place...the catch broke and the hose is loose and the pump keeps pumping...50litres of petrol was gone before I can rush to the nearest workshop...petrol dripping along the whole stretch of highway...scarely thing I went through pal...

cheers,

sam

Thanks for the suggestions. I'll definitely try the CPS first.

One other symptom I'd almost forgotten about is that occasionally, seemingly only when I have 4 people in the car, I get the Tighten Fuel Cap message on the SID. It usually pops up and then dissappears after a short time. Maybe I have more than one problem going on.
