Question about 1990 Saab 900 Hatchback

1 Answer

1990 Saab 900 Turbo

I am trying to help a friend get his car started. He had another friend pull the motor ot replace the seals. After the motor was put back in they couldn't get it running again. I have checked everything I could think of. It turns over without successful startup. I pull the plugs and they are definitely getting fuel. I checked for spark and there is none. Obviously, the problem. I checked the voltage going to the distributer, 10v as descirbed. The coil voltage was correct also, as is the resistance on both the primary and secondary circuits. I have tried to get any kind of spark from the coil, but there is none. The 10-pin iginition connection shows correct voltage also. There is a fuel pump fuse that does show power in the left side fuse box, but the right side fuel pump fuse does. There is also a connector hanging loose coming from the engine harness that holds the injector connectors, it lays out in front of the motor, but I cannot find anything that it goes to within its reach. What else would keep the car from starting or send the spark from the coil. (The coil, cap, rotor, spark plug wires and spark plugs are all new as well) Please help.

Is the knock sensor, mass air flow sensor and all other necessary sensors plugged in? Also there is a hanger bracket on the front of the engine that shares the front two bolts of the intake manifold and there's about 3-4 ground wire terminals that attach to this bracket and the wires come off of the fuel injector wiring harness. I would check these things and any other obvious electrical connections.

How many quarts of oil does the engine hold


I believe that in 1990 the 2.0L was replaced by the 2.3L. The 2.3L was offered in two versions. Standard and turbo. However since there may well have been 2.0L available in 1990 I included both capacities.

  • 2.0L: 4.0 litres.
  • 2.3L: 4.7 litres
  • Grades:Grade: Saab Turbo Engine Oil or an oil which meets the requirements of API SG and CCMC G4 or G5.
  • Viscosity: 10W/30, 10W/40, 5W/30 or 5W/40
If your Saab is the Turbo model please remember to take the extra steps necessary to protect the turbo unit.

#1
Before you add any new oil, fill the new filter up first.
#2
After you have secured the oil filter and refilled the rest of the oil remove the coil wire to prevent the engine from starting.

After that turn the engine over for a count of 10 to 15 seconds. Now reconnect the coil wire and start the car.

This extra step is Critical and Necessary to prime the oil system. If the engine is started with an unprimed oil system and an empty oil filter the turbo will not receive oil for 10 to 15 seconds after start up. Some scientist have speculated that this was in fact an unlikely cause of the last great extinction event that occurred somewhere else. ":->

Hope this helps and good luck.

Rough idle on 1990 saab 900 convertible, 16V


Because the car has adaptive technology, it may take a while to reset and adjust to the new, cleaner and better conditions than those to which it had previously adapted.

Did you change the cap and rotor? if the plugs needed replacement, likely they do too

Possible other causes include:

loose or corroded connections to any electrical component you disturbed (make a checklist and tick them all off as you check them);

mis-reinstallation of any F.I. part disturbed(checklist again)

obstructed water flow through the AIC valve;

improper voltage output from the AIC valve (for LH 2.4 systems, should output 8 volt at idle, dropping as load increases; for LH 2.4.2 system output 7 volt at idle etc; testing between terminals)33 and 17 at disconnected LH connector;

possible problem with MAF.

Hope this helps

Your problem with the APC system. Any perceived fault and you only get base boost. The most likely fault is the boost pressure sensor located under the dash on the left-hand side. when it is bad you often hear the APC solenoid valve clicking at idle.
