I took a video of it struggling to run but I managed to delete it somehow. I have a video of how loud the pump sounds like when you turn the key. Can someone listen to it and tell me if that's normal?

Do you have a locking gas cap? Any PO'd neighbors? I would think about crap (leaves or dirt) in the gas tank.

A pressure gauge would be a good tool for checking this out too.

 

Bump.. Still needing help.

 

Its sounds a lot louder than my aviator which in essense if just a beefed up svt pump. The pump sounds like its working and if your plugs are soaked with fuel, its hard to imagine its not. Are you getting any spark? Did you get the codes checked? Without knowing what the codes are and or fuel rail pressure readings or something specific, its really hard to put a finger on your problem. Your not leaving us much to work with.

 

Yeah sorry I havn't had much time to even mess with it. I'm about to spend some time checking things tonight so I will report back later.

 

Well I tried checking the codes but aparently they were lost when I had disconnected the battery.. Figures since now it won't start so I can't get it to throw a code. I'm thinking though it must be a sensor issue since it ran fine when I first started it (open loop) then went nutty a bit later. The whine from the pump which is definitly working must be the pump going wof. SO I'm thinking fuel pressure regulator but there isn't one.. There is a fuel pressure sensor on the rail and I just so happen to have a spare fuel rail with a good one on it so I'm going to try swapping that tomorrow.

 

I swapped out the fuel pressure sensor tonight and the loud noise from the pump stopped. It sounds like normal now. BUT I still can't get it to start up. I checked and it is getting spark and fuel. Any ideas what I should check from here?

 

Are there any steps I should take to crank it up again after running rich like that? I held it at WOT for a bit while cranking and then pulled the fuel pump fuse and let it crank for a bit to clear the cylinders. Still doesn't start. I pulled the spark plugs and they are getting fuel and I also checked spark and it's good.

 

Man WTF is wrong with your car????? seriously. You've got spark, and fuel, I would be really surprized if you all the sudden lost compression. My gut wants to say crank sensor but its really just a stab in the dark without being able to actually look at your car. I'm sorry man. Most of the common problems like Mafs and stuff will make it run like **** but it will at least start.

 

even though the 02 sensors LOOK ok, they may not be. I damaged one of the front 02 sensors when putting my h pipe in. It looked fine but i accidently let it hang by the wire and i think it pulled apart a little.The two front 02 sensors directly affect the air/fuel ratio, which sounds like the problem here.
