1998 Harley FLHTCI Stalled last night, and would not start. EFI Motor. When it stalled RPM Needle went to zero. Pulled over crank no start. Can hear the fuel pump running. After letting it sit for about a half hour, started and ran for about 3 minutes, then it started to stall, when it was cutting out the RPM Needle went to zero. Then it stalled again. When it would not start there was no spark. Question is, is this a crank sensor gone bad or a cam sensor. Which one sends the siganl for spark on this engine?

 

Did you check to see what code it's throwing? That should tell you if there is a bad sensor in a jiffy. The procedure is in the service manual and is not hard to do.

 

My 01 did similar things....I replaced the Crank Position Sensor...all is well.
