First off yes I have tried other forum posts.

I have a 1991 Volvo 940 SE with turbo and 162,000 miles

The problem is there is no spark coming from the ignition coil. There is power going to the ignition coil but no spark. The car turns over but doesn't start.

I have replaced the crankshaft sensor and the Ignition Module. The wire that goes from the ignition module to the Ignition Coil has been replaced with a new wire that goes directly from the module to the coil (could this be the problem is it supposed to go somewhere else first?)

Also the coil has been checked and its operating within parameters.

Any Ideas?

Thanks,

Robert

Robert,
How did you make out with you problem? I have the same problem but have not replaced the sensor yet. How difficult was it to replace the sensor? any help would be appreciated.

Andres

I have replaced the crankshaft sensor, power stage and ignition computer and no luck

has the cam belt snapped?

First thanks for your help, I haven't checked the Cam Belt. I'll have to look up how to check it. I am new to this, but pretty handy. I'll check it today.

Well cam belt is not broken, this model has a flywheel pick up sensor. Wondering if anyone had any info on the best was to test this sensor. I have electronic test gear at my disposal if needed.
I have already replaces the Ign Module and coil and still get no spark from the coil.
Thanks

To answer the question about the crank speed sensor, it's very easy to replace. It sits on the tranny bell housing right behind the engine near the firewall. one cap nut holds it in, and once it's out, it's as easy as slipping a new one in, screwing it down and plugging it up. If i remember correctly, there was something of a dealer recall on this part...

Dan,
Thanks very much for your info, I am in the process of looking for the flywheel sensor now. It seems to be a dealer only part around here. Is there another source maybe on-line where I could get a good deal. Much appreciated.

Where is the power stage? Is it the little black module on the same bracket as the ignition coil. My 94 850 turns but won't start.
