Hi guys

I was driving from Glendale to Ktown but when I was around Chinatown it die on me while on the freeway I down shift n it got me to Ktown n before I got home it stop n I couldn't start it I turn it on n reg it a little n it got me home. Yes I google already I check all my fuel lines the fuel pump is working. I checked my vacuum lines n they are on the dot. I google n I was reading it could be the egi/egi pump relay n that I need to check the ground cables. I work 8am-1am the next two days n only have Friday n Saturday mornin to work on the car because I work in the night n Sunday I work all day again. So the plan is to check all engine ground wires but I need help with that when can I find them the only one I found was the one by the throttle body n I heard there's another's one by the fire way. Any advice will help?

Thank you
