I replaced the fuel pump 2 weeks ago. Today I started the truck and it ran. As soon as I cut the heat on everything just shut off. This also happened the day after I replaced the fuel pump. After a couple of days. It just started up again. What could it be? What do I have to do?

That is a tough one. When you turn the heat on, does everything electrical shut down?

Make sure the ground from the battery to the engine is clean and tight as well as both battery terminals. To me, it seems that the added load from the blower is causing an interruption in the current.
