I have not checked the wires at the fuel pump, your talking by the tank right? Id suspect if it was fuel related it would sputter, tonight it died once on the way home and I thought oh I'm gonna figure it out, put my hat, gloves coveralls on got the new spark tester out of its package, popped the hood, thought well I better try it before I hook it up, bam started right up!!!drove to the liquor store grabbed a six pack, took some pics and here I am.Ill try wiggling those wires once it gets up to 20. Whats a ic filter?Ill chase the wires back a little off the coil and spark ignitor, see if that gets me anywhere. Thanks MM
