1992 Honda Accord start-up sound is a low gurgle rumble grind

I have a 1992 Honda Accord and it is making a weird gurgling rumbleing grinding sound at start-up. It is not making the usual high pitched ignition start-up it use to do. It almost sounds like something isn't plugged in right. I just had the main relay and wires to the relay replaced. It started up fine before I took it home after the repairs. It also started fine 3 or 4 times after that. But after being outside at my work for 5 hours it had this terrible sound! And it is still there after being cooled off in a parking garage over night. I feel like something is going to break if I keep turning it on like it is sounding. At least it starts now. Any ideas on what's wrong?
