Help
Back in August I had to replace the fuel pump(it Died). I replaced it with an OEM replacement from Ebay - seller "SolidPro_auto_parts" Cost $184.00 1 yr warr.
Since then I have encountered a hitch in it performance occasionally. Every so often I needed to switch the relay(box under hood) with another relay and the pump would work?????(Stumped) A week ago I pulled in the driveway shut the truck off, never to start again. (p.s Frigid temps, no garage) I have replaced the relay with anew OEM relay. No start. Checked for continuity from the relay socket to the pump. Sometimes there is, sometimes there is not??? Not sure why? What this about an inertia switch?
Any help will be greatly appreciated.
