Hey every one, just wondering if anyone else has had this issue. After a 3hr run lets say from MPLS,MN. to Duluth, MN. 190 miles. I get to hotel turn key off and pull it out but truck still running. this has happened a couple times now. I let it run for bout 10 minutes while I checked in but still wont turn off. had to put in gear and let clutch out. thnx in advance.

Fuel shut off solenoid stuck in the up position. Double check the linkage on the P7100 isn't sticking or hanging up.

 On a 2001 truck? That's what his garage says anyway.

Posted in the 12V so I'm assuming P7100 pump.

 

On a 24V truck I would look at the fuel pump relay in thee PDC to see if its stuck ON. If so them the the VP44 remains powered up. Just swap fuel pump relay with something else to verify.

Posted in the 12V so I'm assuming P7100 pump.

 

 

OOOPS, I missed that.  I pulled it up from the recent topics.
