As Mark says + make sure you have a ground cable/strap connected battery direct to your starter. Do not expect starter to ground through your engine without problems.
I remember Tracy posting on this issue years ago just a bit hard to find in the archives now.

Bill, 

You may want to check your engine ground.  Starter current may be causing this.

I am working on cleaning up my ground system and I noticed that I have
several, 3 or 4, places on my SS braided fuel hose that appears to be burnt
like it had an electrical spark exit from it.  I have not found anything in
the vicinity of these places that look like where the spark? would have
jumped??

Has anyone seen something like this and what should I do about it?  Do I
have a ground problem in the engine compartment or is this maybe static?
The hoses are covered by SS and are connected on one end to a filter that
has a ground strap on it and on the other end to the fuel rail which is
grounded to the engine.
