I have a 2000 F-150, 5.4, 2wd. It sits dead in my driveway because I am unable to start the darn thing. It all started a few weeks ago...it was strange because the truck started to give me troubles when starting it. I could eventually get it started after turning off the key a few times, then starting it up. Someone told me that a fresh battery is required for the fuel injectors to operate correctly. Therefore, I broke down and bought a nice battery charger and made sure my battery was at full strength before starting it.
I put the key in, turned the key to on, heard the fuel rail make a thump, then tried to start the truck.
It just kept turning and turning with no start.
I need to know something...the only sound that I hear before cranking up my truck is the fuel rail making the thump. Am I supposed to hear the fuel pump in the tank prime? If so, I am not hearing it.
If the fuel pump is bad, will the fuel rail still make this thumping noise?
I am dreading to call a wrecker and take it to Ford.
Like I said before, I have...
1) Changed the fuel filter
2) Changed the cam sensor
3) Changed a few vacuum lines that looked really bad
4) Changed out the fuel pump relay
5) Checked all the fuses
6) Made sure the shut off button was not activated
What am I doing wrong? Is there a timing issue involved?
Thanks for your inputs.
