Was driving home, car just stopped running, seemed like it wasn't getting fuel, replaced the fuel pump, check relay, car will not turn over. Took it to the shop, they said the cat is clogged thats why its not starting. I know a clogged cat will bog the engine down, but never heard of it not allowing it to turn over. So I took it home and found no power to the fuel pump?

Have the same problem with 2001 Santa Fe. Was running great, then wouldn't start next AM. Checked relay, fuse, power at connector on pump, reset fuel cut off switch. I replaced the fuel pump and still won't start so I changed the fuel pump relay out all fixed! I love this site.
