Question about 1990 Saab 900 Hatchback
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.
