Please help! I went out the other night after driving my 03 f150 5.4 to work, and it would not start. the engine will crank over but it seems like it is not getting fuel or spark. I looked in my haynes mannual and replaced the camshaft sensor, fuel pump relay and I do have power going back to the fuel pump harness were I can get into and unplug the harness before the fuel pump

The pump will do the prime but after that when you try to crank it over no fuel will come out.

Could this be the fuel pump.

any help would be great, my truck has been dead for 5 days!

 

Try disconnecting the fuel filter and see if fuel comes out before the filter.

 

Hi, how did you fix this, I have the same problem.
