I replaced the forward pump. It doesn't seem to be a fuel issue (I think), as clearly there is no spark when this happens. I also bought an inlime amperage tester, so I can see what the pumps are drwaing in terms of juice. $15 at harbor freight.

I thought about replacing the coil, but wish there were a way to tell for sure. If I replace the coil, and its not at fault, then I still have to buy a new CDI such as the MSD and that requires its own coil...

I bought an inline spark tester light, and plan to install it inline with the lead that goes to the coil. Seems to me if there is juice there, but none at the spark, then the coil is bad. Otherwise, its the CDI.

If this works, then folks on this board will have an easy way to test this in the future . The inline tester was only 5$ at harbor freight...
