Fuel cut issue?

Hey all

The truck
Harrop supercharged stage 2 with 142k miles total, 20k on the supercharger kit(including fuel pump harrop supplies, i believe its a walboro 340)

Back story, The last 5-6k miles every now and then the CEL will illuminate and the trac will be disabled for the truck running lean on banks 1 and 2, it would go away if i drove the truck normally and didnt hammer on it (for about 300-500 miles)

last night i drove it about 2 miles down the road to a park and back, on the way back i did a pull and at about 6k RPM the truck just shut off, i thought the engine was done for but i now believe its a fuel related issue as i did a compression test and it seems fine and theres a code P0230 “fuel pump primary circuit”

The fuel pump fuse is OKAY, the 2 relays that control the fuel pump have been switched around with other assumed good relays to no avail, the fuse inside the cabin(i forget the name, someone online said it controls some relays) is also good, does anyone have any idea what could be the cause? Bad fuel pump? Bad wiring? Any information on how i could diagnose this and find the problem would be extremely appreciated.

i have an autel maxicom 908p so if theres any specific info from the ECU that would help or live data needed to confirm let me know and ill post it, thanks!

 

I don't own an SC Tundra, but I'm a ask a dummy question. Is it tuned? If it's not tuned, your ECU may be overriding your supercharger and leaning it or cutting fuel out since it's probably not sure what is going on. If it's not tuned, I would suggest you get that done first before pulling any more revs and destroying the engine.

 

I guess i shouldve said the truck doesnt start at all any moreC it turned out to be a loose wire on top of the fuel pump causing a short and blowing the fuel pump fuse
