I dont know why my truck wont start
I have a 1991 chevy silverado 1500.
I was driving and hit the gas to pass
some traffic and my truck died. I
couldnt get it to start backnup. A
friend towed it back to my
appartment. I thought it was the
fuel relay switch so i bought and
replaced it. Fuel pump engages now
but my truck still wont start. What
should i be looking at now?
