2000 p-pump..truck has only 120k on it and i did this swap back in 2015. truck has always been reliable and no issues. in early 2018, i parked the truck. i got the tuck out this past may, the plunger was not pullling up when I hit the key so I bought a new plunger and it ran fine.In August I moved the tuck into the shop to do a little work on it and went to restart truck, would not start. The plunger would stick up by hand, so i replaced fuses and that did not help. I checked the wires to the fuse panel, all looked good and frankly gave up...came back out about two weeks later and it fired right up...no more issues...this past monday night, i used the truck for about an hour and parked it. Now, no start again. I checked the fuses, good, but when the key is off, i have power to the plunger, when the key is on or cranking, no power to the plunger according to the test light.....im at a loss here....any ideas?
