For a week or so my truck wouldn’t start without me cycling the key off and on a few times. Then one day it didn’t start at all. I’ve tried jumping it off, but the battery seems to be fine seeing that I still have power.

Hi,

If you had to cycle the switch for it to start, it sounds like the fuel pump failed. By cycling the switch, it was able to prime the system a few times to build the pressure needed.

Here is what I suggest. See if it starts with starting fluid. If it does and then stalls, we will know it is a fuel-related issue. If there is no change, check for spark to the plugs.

Here is a link that explains how it's done:

Let me know what you find.
