my f150 has the 4.6l v8. it turns over fine but will not start. we have determined that we have fuel pressure all the way to the engine. we replaced the fuel filter and it started twice then wouldnt start again. we replaced the fuel pump and same thing started twice wouldnt start again. replaced the fuel pump relay and same thing started twice and then wouldnt again. the fuel pump fuse is fine. we have fire (atleast most of the time, its hard to check because of the long snout on the plug wires on this model, but because it starts sometimes after fiddling with a few things i believe we do have fire.) if there is anything else i can do please let me know. i'm getting desperate because i need my ride to get to work on monday. thank you for any advice and time you can give me.
