Fuel Pump Inertia Switch Wiring For Beginners With A Relay **parts list in description below**in this video, i show how i wired an inertia switch and fuel pump relay into an electric fuel pump circuit. i use a 4 pin. Step 1: gather the necessary tools and materials. before you begin wiring the fuel pump relay, make sure you have all the necessary tools and materials at hand. this includes a wiring diagram for your specific ls swap setup, wire strippers, crimping tools, electrical tape, and a multimeter for testing.
Electric Fuel Pump Wiring Has three terminals, one to the ignition switch ign terminal, one to the ignition switch sol terminal, and the other to the pump. so it gives the pump power when it's cranking and there's no oil pressure, or when there is oil pressure (either cranking or not). ps 64 from standard motor parts. The oil pressure switch will shut the engine down if the running oil pressure is below aprox 5 psi and the inertia switch will cut the fuel pump ifi it is tripped due to a collision. the oil pressure switch has a built in bypass that will allow the fuel pump to run during start. john. the fauxstang. dynacorn 67 fastback. You can have the fuel pump relay simply supply power for the fuel pump and have that power go through the inertia switch as a safety. or you can have power ( or ) for the relay coil go through the enertia switch to power the realy and then power for the pump would be direct from the relay. not sure how the rf harness is set up but it sounds. Tester. ok4450 november 20, 2018, 5:37am 3. ford had 2 methods of wiring the fuel pump, pump relay, and inertia switch. one of them involved running the power for the pump through the inertia. the other involved the inertia switch being used as the trigger circuit for the pump relay with power being fed directly to the pump from the relay.

I narrowed it down to the power distribution module fuse panel. the fuel pump relay is a pcb mount type on the circuit board. the relay was bad and wouldn’t carry any current. could disconnect inertia switch and there was voltage on the wire going into the switch. if you put any load on it it would open. The diagrams and photos show how to wire up the fuel pump and oil pressure switch to a commonly available, industry standard, iso type "1 form c single pole double throw" (spdt) relay.
