2000 Volvo S40 Cqar won't Start

Electrical problem
2000 Volvo S40 4 cyl Front Wheel Drive Automatic

I cannot start my S40 without jumpingout the start imobilizer contacts on the relay. For some reason the relay coil is not getting power? Where does the coil to that relay get its power?

Do you
have the same problem?

On the starter motor immobolizer, check pin 3 for power. If you have no power check fuses in engine compartment and look for fuse #14 40A fuse to see if it is blown. If it is replace. If fuse is good, make sure there is power. If power is good check continuity from pin#3 on immobolizer relay to the fuse. If no continuity then you have an open circuit and you will need to find it and fix it. If that looks good, check for power to pin #1 on starter motor immobolizer when you turn the key to the start position. If you have no power check for continuity from pin #1 on immobolizer to pin #4 of the ignition switch. If no continuity then you have an open circuit on that wire. If it is O.K. Then you have a faulty ignition switch. Hope this helps and let me know what happens.
