The return line on top of the pump.. remove it..
If it has a checkball fitting on the top cover, remove it also..
with the line off and the connector off, go ahead and start it.. now piece by piece, reassemble it.. waiting for a 10 count before assembling the next piece..
Once u find the piece that shuts the motor down, clean it and repeat the test..
Good luck

will do, but I pulled that line off and am getting fuel out of it going back to the tank. if something was going on in there wouldn't it effect the fuel flow..? thx, I am gonna try what you said as because I was getting flow I did not take the check valve apart.

Yes, take the fitting off the top cover.. if done correctly u will b looking into the hole in the cover ..
NOW, try to start it.. fuel IS GOING TO flow out so b prepared for that, if need be, put a pan underneath the machine..
Good luck
