Hello guys, been a while since I post on here.

I ran into an issue this weekend where my fuel pumps shut off while driving, I was cruising around 60MPH when my A/F ratio leaned out and fuel pressure dropped instantly. Long story short, got the truck home and started messing with it, checked fuse 10 and seemed to be okay but changed it anyways. I started the fuel pumps directly by skipping the relays and the fuel pumps started right away.

My next step is going to be changing out both relays hopeful that does the job.

Has anyone else ran into this issue?

I am running Walbro's 450, with an upgraded wiring kit.

450's are too much for the factory wiring, you need one of Josh's fuel pump wire kits.

Fuel pump resister next to your IC pump might have taken a crap🤔
mmm I'll check that after I check the inertia switch.

The odd thing is that the fuel pumps start if I bypass the relays and run power directly to them.

I believe Joshs Kit bypasses the resistor. Mines still sitting on my work bench so I can’t confirm
