Fuel pump no prime pulse, tps 30% at Zero

Fuel Pump doesn’t prime or receive signal from fuel output wire.
I’ve had a checklight probe AND multimeter on purple wire pump pin 37 and light doesn’t flash,multimeter doesn’t spike, and fuel pump doesn’t hum. I cannot test FP also. Injectors work in test mode so far but Fuel Pump on and off options don’t click or shade to represent me clicking on them. I’ve tested every relay I have and same result. When I use a jumper from power to 85 or 86 on relay the FP turns harness connectors and taped everything off in case of weird contact somewhere. The TPS negative is negative is connected to water temp sensor, Intake temp sensor, and AFR gauge . And I’m breaking my head with all of this .. if I need to somehow make a log or someone wants to take a look I am headed home now to do so.

I'm not sure if I quite understand how you've tested this, but you do realise that the FP output is a ground - right? So the other side of the relay coil must be 12V.
See the wiring diagram in the MS3 Hardware Manual.

Thank You James. I thought I've tried each and every way but I will adjust. And let everyone know.
