My buddy has a '98 WS6 and sunday he went to a friends house and went to leave and the car wouldn't start. No symtoms or anything. We found that it has no spark, and is getting fuel. We put it ona scan tool and found that when we try to crank it the scan tool is showing 0 rpms. I was thinking maybe the crank sensor, but I need a little insight. If it were an LT1, I wouldn't be so lost. Thanks for any info or suggestions.

 

I think that you are headed in the right direction.
