Why is it when I go to start my 2000 F150 5.4 Liter Lariat it will keep turning but will not start? I have to give it some gas to start it every now and then. It happened to my parent's Expedition and the dealer said to let the engine sit before starting it, as if it was a deisel, but that does not work all the time for my truck I need to give iot some gas to start it. Do I take it into the shop or is there a way to start the truck right? Thank you, Justen

 

Take it in and get it looked at. I have had two 2000 model 5.4Ls and have never experienced this problem. If your dealer does not seem to be helpful, try another. There could be several possibilities causing this..but you should have it looked at.

Justen: Welcome to the site. No, this is not normal for me or any similar truck I've been in. This problem needs experienced diagnosis; fuel system, ignition, etc. Being under warranty, I would just take it in.

If you're running high octane gas, try a lower octane. Otherwise take it in, it should start and run with out using the gas pedal.

 

A shot inthe dark, but I'm guessing that the check valve in the fuel sending unit is bad... by waiting, you're allowing the fuel pump to repressurize the system. This should not be necessary if the check valve is working correctly. Take it to the dealer (especially if it's still under warranty!). What you describe is NOT normal and should be fixable. Keep us posted.
