Most likely your fuel pump took a dump. Do you hear the fuel pump when you first try to start it. If not your fuel pump is the problem. You can verify this if you don'the you don't want to throw parts at it by connecting a fuel pressure gauge to the fuel rail and turn the key to the run position. You should have a fuEl pressure reading of 50 psi at the gauge.

I have installed a new fuel pump. And a new housing for the pump
Because i broke the nipple on the top of the cylinder when trying to remove the outlet hose. I can verify that the pump is indeed turning on when i jumped the relay but the car will still nof start. Im at work so i dont have time to read the post above yours but ill check it out when i get home. |

On my 4.6is my fuel pressure regulator was bad and caused the same problems. It went out over the summer. I just replaced it and it started the first attempt with no issues. My filter I removed had a date of 11/03 so it was the original.

So the fuel pressure reg is under the hood? Did you troubleshoot the bad one forst or did you just replace it? Im going to have to check the pressure tomorrow when i jump the relay again. I guess the relay is bad as well. Its gotta be something todo with the electronics as i cant hear the pump click on when cer is turned to the first settinf or second but i so when its jumped.
