Okay, so, the starter cranks and the battery has power. Lights don't dim I have a half tank of gas never had this problem before with my truck starting. I drove to the store and I came out of the store and my truck won't turnover all the way the starter cranks but won't turnover all the way. Maybe it could be the fuel pump? Or what?

Hi,

These symptoms are usually related to either a fuel pressure issue or a loss of ignition spark to the plugs. Here is what I want you to try. See if the engine will start with starting fluid. If it does and then stalls, we know it is a fuel-related issue. If there is no change, I need you to check for spark to the plugs.

Here is a link that explains how that is done:

Let me know what you find.

Take care,

Joe
