Electrical problem 4 cyl Automatic 120000 miles

my hyundai died and would not restart checked fuel pump, fuse and relays. I found that I was not getting power to the 12 volt side of relays control side was working. Wiring diagram shows straight from fuse box under hood to both relays. Any ideas? Car turns over and fire with starting fluid

Check the fusible link B 20 amp blue if okay could be the computer fuel pump control of the relay. Pull on the link see if it is rubbery. Here is the wiring diagrams for the fuel pump and engine.

I have checked the fuses and fuel pump they are good. This wire should be hot all the time and it is not. I feeds directly from the under hood fuse box to the relays (fuel pump, mfi relay). It is not controled by the ecm

It must be a broken wire or bad connection. Here is the full engine and fuel pump wiring diagrams so you can see what to how the system works and a guide to help you check the wiring.

The white/red from the fusible link to the fuel pump relay also feeds the fuel injection relay. Cant see the whole diagram but thats the wire.

That wire feeds both the fuel pump relay and the main control relay.-Try a jumper inline fuse wire from the battery and see what happens. Also check the B/Alarm fuse 10amp does it have power-
