The quad died the other day, no spark. As I'm looking around I find the 15 amp fuse blown. Replaced it. No help, but it did not blow again. After looking for a while I find I have no power to the fuel pump either. The pump is fine, but is never getting a signal. The pump relay would not keep me from getting spark, but can the cdi kill the signal to the pump relay? Thanks, Mike

 

Here are the ignition tests & fuel pump tests

The quad is in Mexico and I am in California now, but I did some testing before we left. The coil looks good. There is no power getting to it. The manual is not really showing a way to test the fuel cut relay, just jump around it and see if the pump works, it does. It seems I am not getting a signal on the bu/y wire, or is it a b/y ?, I can not make it out on my diagram, to the coil and FCR.

 

Msteve, I realize this post is ancient and dead. still wanted to ask the outcome because I have the same issue - no spark, no fuel pump activation. Just no fuse blown that I can tell.
