Ford Repair: Truck not getting gas when starting, inertia switch, fuel pumps

Question
Hello, I have a 1991 Ford F150, 300 Staight 6 cyl.
The truck will turn over but not start.  This truck has 2 tanks so I am assuming it has 2 fuel pumps.  This should rule out a bad pump.  Could this be a clogged fuel line or filter and if not what else could it be.  Any advice would be appreciated.

Thank you ,,KJ

Answer
Hello and thanks for the question...I'll try to help.
I wouldn't rule anything out yet. Check to see if either of the pumps is getting voltage to activate it. Also, check the inertia switch to see if it has been set off. That will cut power to the pumps and will not let the vehicle start.
Hope this helps,
Erik
