Mechanic's Assistant: Have you ever replaced the fuel pump, or is this the original?

I just replaced the fuel pump yesterday

Mechanic's Assistant: Are you fixing your F150 yourself? What have you tried so far?

I replaced the fuel pump, and ran a circut tester to the harness to see what was wrong, my orange wire has no voltage coming from it

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I did try the inertia switch, that is fine and opperational

Hey how are you,I will try to help you with this issue

click on link to view fuel pump wiring diagram

where is this orange wire located on the fuel pimp connector

based on these diagrams orange wire goes back to black which is ground

at the fuel pump relay there is 4 pins, , a red ,a yellow light blue/ orange , a dark green/ yellow , tell what you have on them

if the fuel pump not running,. if you spray starting fluid on intake or tb body does start and run and dies ?

If you do not mind me asking ,are you looking at fixing this yourself or looking to know the most possible cause of this issue and taking it to repair shop for the work ?

Do you have any prior experience in electrical troubleshooting and testing with a test light for power & ground ?

Do have a power probe for testing ?

Do you have a test light so we can check for spark ?

Do you have fuel pressure tester to check for fuel ?

Did you scan it with factory scanner or equivalent to retrieve faults codes for vehicle modules ?

Please let me know

Thank You

okay so
1. the orange wire is located at the far right end of the connnector that goes into the pump/sending unit.
2.i have (in this order) a black, a dark green/yello, a red, and an orange
3.i did not try to spray anything yet, but when i try to start truck, it shakes a bit and cranks, no whine coming from pump like i did before the old pump died.
4.im looking to fix it myself.
5.i have experience with troubleshooting.
6.i used a power probe for testing
7.where would i check for spark?
8.i have a fuel pressure tester which i will use to check my pressure for fuel
