!988 Truck stalls intermittently

[Randytelecaster]

Really need everybody's help on this one. Have a friend who has about a 1986 Nissan truck that has a 1992 4 - valve engine engine . The truck runs fine but every once in awhile it will spin over but not start. Wiggle the fuse box and it will. I've changed the relays with OEM parts and still happens. What is my problem?

Wigging the fuse box helped but replacing the relays didn't? The issue sounds like it's wiring at the fuse box. Check to make sure all the pin connections are secure. Don't throw anymore parts at it until you know for sure what you need.
