2005 F150 5.4 triton 4x4 extenda cab turns over but wont start,
So here's what we tried,
listend for the fuel pump and we hear nothing.
pressed the emergency fuel pump reset switch.
pulled the fuel line off just ahead of the fuel pump turned the key and no fuel comes out.
removed battery post connection for a couple of minutes thinking it would reset the pump.
tried the spare key incase the chip was defective.
and nothing, do you think I should chance buying a fuel pump and go ahead and change it?

sounds like to me a fuel pump would be a good investment.

Bert

It probably is the fuel pump. You will only hear it for a few seconds when the key is turned to on.

truck is running now,
all I did was take off the fuel line before the filter and tried to siphon the tank for removal, that don't work so I kicked the tank a couple of times and when I was giving up I turned the key and the fuel pump started to pump, hooked up the fuel line again and the truck has been running since.
Should I still change the pump?
Thanx

Bert

I would definitely change the pump if kicking the tank made it start working.

detrik

does anyone know where I can find the tankand pump removal procedures, (pics)
that would be awesome.

Bert

See if your library has a Haynes or Chilton manual. They're worth having your own for other help too.

No, not yet. The problem could very well be an unreliable electrical connection, (and since you didn't say it began working *when* you kicked it) a bad tank selector switch, or the fuel pump relay. The pump itself may be fine.

Checking the relay is simple. And assuming the fuel pump is situated similar to other in-tank pumps, the replacement job is a serious undertaking for someone unfamiliar with it.

Also (and I'm referring to the the arrangement in an older truck; you need to look up the connections for your year and engine), you should be able to jump two leads (connector 2 & 6) in the test connector to make the fuel pump turn on and *not* turn off after a brief interval.

The relay is in the front of the truck and kicking the tank wouldn't jar it. There can be a poor connection but I've never seen one on any of the newer vehicles. If someone was messing with the wiring at some point, then I'd wonder about the connections. There are no tank selector swithes on the newer trucks.
