Come from work this morning and all i wanted was to get some sleep. Then my mother wants me to go to the bank with her to help cash some money orders. We drive to the Citibank and do what we needed and come out to start my car and it wont turn over. I dont even hear the little "WHINE" noise the fuel pump makes when you put the key to acc. I then ruled things out and went and bout a delco pump which cost me $320. I install it and my fuel gauge wasn't even moving with the new pump. I take it out and install the old pump back in and the gauge is back to working but car still wont turn over. I look under the hood and check the fuel pump fuse and its fine. I switch the fuel pump relay with the Daylight running light relay and try to start the car and still nothing. I replaced the fuel pressure regulator just last month with a auto zone brand. Don't know what else could be the cause but im not giving up.
No check engine lights or codes what so ever.
i need wise advice, help and guidance.
