I have a 1995 Saab 900 SE turbo, when going upgrade the acceleration is poor and has no power. I replaced the spark plugs and still doing it. Any help will be appreciated.

It sounds like you may have a vacuum leak at the throttle body, inlet manifold or associated hoses. If there is no leak, recheck the spark plugs to ensure you set the correct gap on the new spark plugs.
If the noise is just a spinning sound and not a grinding, than you're starter solinoid is probably bad.
You're best bet is to replace the starter. Hope this helps.
A SAAB dealer should be able to print one out for you. BTW that engine is practically identical to the V6 used in a caddy Catera, and Saturn Ion. Those diagrams would be the same, so you might want to search that also.
If you have plug wires you have a naturally aspirated Saab (non-turbo). The entire ignition system must be checked. First, replace the cap and rotor. They are wear/maintenance parts, are cheap, and can be gotten at most auto parts stores (even for Saab). Next, if the high tension leads (plug wires) had cracks and that is why you taped them up, they MUST be replaced. Mere electrical tape will not prevent voltage leakage through these cracks. Make absolutely certain the plugs are resistor and of the proper specs for your model year and engine and that are gapped dead on to spec. Another common wear part is the cam position sensor (a Hall effect sensor that tells the ECU what position the cams are in). You did not mention whether the CEL light is on or whether you retrieved any codes from the OBD port. Go to Autozone or Advance Auto and let them put a code reader on the port to see if you have any active and stored codes (this is free). Finally, a crankshaft position sensor (crank angle sensor) failure could be imminent. This is a known failure part as well.
i have a saab 900 se conv that i am going to do the same thing. i think im just going to go with the same color, and same patterns of the old seats. i will just add some ripples, new heated seat elements, and speakers. and also i am going to look into adding vents with fans for cooling.
Sounds like an ignition problem.. The Direct Ignition module in the turbo model can fail but is
easily
tested and replaced.
Remove turn the , Direct Ignition module put the spark plugs in the holes, ground each
plug to the negative battery terminal by use of a wire about 2 feet
long and stripped at each plug. Crank over the engine
over watching the spark plugs. If there is a problem with the cassette, one
of the plugs will have no spark or a very weak spark. Also, when you
turn the ignition key off there should be a shower of sparks that runs all of the plugs simultaneously several times. DANGER BE CAREFUL ! ! ! EXTREMELY HIGH
VOLTAGE! There have been occasions when the Direct Ignition module would test ok
when turned upside down but would fail when turned back over to install
into the valve cover ? Also: Oil leakage from the individual coils of the Direct Ignition module have also been a problem. Oil leaks can be identified by
noting that there is oil surrounding spark plug hole. Hope this helps. Cheers MMP
