Where is the fuel switch? i was driving and it suddenly shut off and some guy told us it might be the fuel relay switch got bumped or something. it was all good and running and in a intersection it just shut off.

Lights go on. i turn the key and it makes a starting up noise but just keeps going and the fuel pump isnt getting any fuel.

how do i do a fuel pump pressure test? someone told me it might be the timing belt, and someone said the fuel pump another said it migt be some loose wires. i have no idea what it is. everything was good and it shut off when i went over a speed bump.

you have to start somewhere to eliminate the most common issues before guessing you need a timing belt. Typically the problem is no spark or no fuel. You check the fuel pressure by taking a pressure gauge and attaching it to a value usually found on the fuel rail. You may be able to rent one at a local auto parts store.
