Subject: Re: '95 Saab 900 cranking


Longer cranking time is probably due to the loss of residual fuel pressure over an extended sit time. While the system holds some pressure for a while, eventually, it will lose enough pressure to have to start over when you do try to crank it. Nothing to fix, this is normal unless the pressure falls right away. The colder it is the more fuel it takes to start it. If the cranking speed seems fine, the battery is not the responsible party. If you continue to let the car sit like this, you might consider buying a battery cut off switch or disconnecting the negative cable. It is not good for the battery or charging system to constantly be drained and force the alternator to rebuild the charge every time. Check the electrolyte level in the battery as well. The computer systems and clock and radio memories normally draw current from the battery while sitting. enough of a draw to weaken the battery after repeated episodes. Saab ships the cars to the US with the fuses to these draws removed to avoid the problem during shipping. And I hope you are changing the oil at least every 6 months even with the low miles. Moisture from condensation will still contaminate the oil while sitting.
