I just recently bought a 1992 toyota pickup put a new motor in it and got it all done when to start it and it just turns over my and my brother tried everything new fuel pump new efi relay but still won't start

 

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.

 

I did jump the b+ to fp it worked for like a sec but stopped working

 

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)

 

I found the problem it's the mass air
It fried

 

Yes engine swaps can be tricky once all the bugs are worked out you will love your 3.4
