I had to replace the lift pump on my truck. Started it up and ran it for 15 minutes. I went to take it for a test drive and the gauge went to empty and the low fuel light came on and it died. I can't get it started again. I hear the lift pump come on but it won't start. I think it's electrical but not sure where to start? Any help would be greatly appreciated. I kinda need the service truck here at planting time. You never know how much you need something until you don't have it.
