Hi i have santa fe v6 3.3 2007 does not start it turns over, inreplaced fuel pump and was working for one day but now the issue is back
Check or replace your fuel pump relay. If all looks good, you will want to test for fuel pressure. You will have to buy a pressure gauge if you don't already have one. If you're getting the proper pressure, you will then want to check for spark. Post back with your findings.
