It runs well almost. It will run for just a minute and then stop. Sounds good but just will not stay running. Any ideal what I have done wrong. All new sensors has the booster fuel pump stock pump in the gas tank. Well check fuel pressure tomorrow. Or am I looking in the wrong place.
Who Tuned it? Or has it been tuned yet?

You could always do away the booster pump and just toss a walbro 255 in your tank. Thats what Im doing with my maggie setup.

This is the one I have now.
Got it going. Forgot to cut the Tan and Black wires on the MAF and put them on the new sensor. But it is Idling way to high. At 3000rpm's. Did not get to put the scanner on it but will tomorrow.
Sounds like a severe vacuum leak. Have you cleaned the TB bore and checked for vacuum leaks at the intake gaskets, brake booster hose or booster itself?

No have not. So a high idle can be from an vacuum leak?
Found the leak. It is at the TB gasket. Now getting one. Should have known better than to use it look bad to start with. It had been bent.
Well got a new gasket coming. Did a scan on it and came up with two codes. PO405: EGR Position sensor circuilt, low voltage " Truck dose not have one and never did??? Not even a plug for in on this truck.
PO343: CMP signal constantly high " I put in a New sensor before putting on the Blower" any clues what to do. And if I do have to remove it any clues on getting it out with the Blower on.
