Yes the pumps can stop working intermittently especially when hot. Once they cool don they will start to work. They can also cayse stalling and/or starting problems.

Customer:

the truck started then stalled took awhile to get restarted changed fuel filter, truck started then stalled,waited 10 min now runs ok. how can i check the pump,to make sure that it is ok dont want the wife calling in the am

Customer:

is there an ohm reading or psi check that can trouble shoot the pump without removing the full gas tank

Richard :

You will need to install a fuel pressure gage to the rail and verify the fuel pressure. This will tell us if this is a pump problem.

Customer:

ok what is the correct fuel psi

Richard :

You should see between 30-40 psi.

Customer:

does the pump constantly run or does it turn off at a set psi

Customer:

thank you richard for all you help,looks like its going to be a long day for me,have a good night and thank you

Richard :

It constantly runs as there is a return line that sends the fuel back to the tank.
