RE: 1998 ranger 3.0 liter-fuel pump/relay issues
Just went out and put charger on battery to 50amp start setting for 5 minutes. Turned ignition key forward and actually heard both relay and pump. Started right up. There must have only been enough juice to turn engine over and not enough to close relay for fuel pump. Battery is original! 687 000 km on the truck. I think I've got it figured. Just to let others know, I found two wires pooched in wire harness on driver's fender. One was white and fully corroded for 6", nothing but green dust inside insulation. And one yellow one had insulation worn through from rubbing and copper had corroded bad. Cut out bad sections, soldered them up and heat shrinked 'em both. These had nothing to do with not starting, but couldn't have been good. Thanks to all the other posts concerning similar situations.
