My 2013 5.0 has recently been giving me the following problem: On startup, the gas gauge reads near empty, even when it isn't. As I drive a few miles, it corrects itself. Now, that was the problem until this morning. It being cold out, I cranked it up and went inside for a few minutes to warm it up. When I came out, engine was dead. Battery is good, and it cranked but didn't start. Tank read empty, when again I know it's not. Just to be sure, I pulled out the gas can and put in a couple gallons. No dice. Is this problem common? Is it the sending unit? The fuel pump? Thanks in advance for your help.

 

As much as we would like to think a simple diagnosis is possible , it just is not !

There are a number of possible reasons and each has to be checked out based on what we find with each check.

To suggest you should replace the fuel pump module which includes the gauge section, might cure the problem, but without actually running some tests , could be spending your hard earned $$ without being sure that was the problem.

IF,,,,,,,no fuel to the engine is the problem, there could be poor electrical connections that when disturbed as when a new fuel pump assy is installed and great the engine starts now and runs , but the same darn problem appears a week later because of a faulty diagnosis..
The better way to tackle this problem would be to thoroughly check all power and grounds to the fuel pump module and confirm what we might suspect.
Hope this opens the view to avoid making a possible expensive mistake.
