95 turbo, no +12 @ coil???
hello all first post, first volvo, a 95 850 turbo. picked it up for 600$.. nice body, it needed a cv, the drivers seat unreclined and the glove box opened... good deal!!
so, six months later the check engine light comes on. i change the plugs and clean the engine bay..... it won't start, clean and dry the plug wires and coil... it starts. cool.
half hour later crusing down the road @ 50mph the enging dies.... no spark... assuming water in distrbutor, i replace the well worn cap+rotor, still no spark...
i have now swapped the cam position sensor with a "believed" good one... and verified that the power stage is receiving 12volts and .11 volts from b11 on the fi ecu... what next???

RE: 95 turbo, no +12 @ coil???
by the starter disengaging i meant that it will turn the engine over for a few revolutions then it stops spinning the engine and just the starter spins... when i let off the key and wait for the starter to stop spinning and hit the key again it will turn the engine over a few times again before disengaging... i assumed it was a worn out starter? could it just be a ground issue?
also is there a bench test for the ignition amplifier? its just a transistor right? how about the cam position sensor? i used to do electronics for a living and still have some equiptment..
