Do you have all the induction plumbing hooked up? Do you know that there is no power to the fuel pump?
Start with your voltmeter on the B+ terminal in the diag connector. Should have 12v with key-on. Then jumper it to FP. If it starts now, your problem is in the VAF-COR circuit.

Induction plumbing? Did you check for voltage AT the fuel pump? Did you check for voltage on FP?
This is only a few short pieces of wire; you just need to check for voltage where it is supposed to be. If it's not where it's supposed to be, that will point you right to your problem.
(I get the sense you don't have a multimeter, and you're trying to avoid revealing that. Don't waste your time on an electrical problem without one. https://www.harborfreight.com/7-func...ter-90899.html)
