wont' start
2000 expedition 5.4liter won't start. Here's what happened. Went in to store came out exp won't start, lights and all gauges work fine turn the key and nothing. When I tried to crank it the lights didn't dim at all which makes me think it is a problem before the firewall mounted relay. I'm just not sure where to look. I did remove the starter and take it to autozone and it tested fine so I re installed it and ban it cranked, until I turned it off...now it won't turn over at all and still the lights don't dim when trying to crank. Any ideas?
Thanks
Jason

If it starts in any gear other than Park or Neutral that narrows it down to this sensor. At least that is the way my deductive reasoning sees it.

You're correct IF the sensor is just misaligned. If however the contacts inside the sensor are fried and do not ever make contact, then this test will not yield any results.

You have a bad cable or a solenoid. When you turn the key and it doesn’t start is there a CLICK or a small click. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com

<o> </o>
If you hear a big click the solenoid id good bad starter.<o></o>
If you hear a small click and no Big click it the solenoid<o></o>
No small click.<o></o>

State with your key. Where the key ring is there is a little square. Make sure it is there. It has a RFID to enable the start. If that is there, go change the starter relay or check cables. <o></o>

What did the problem end up being? My 00 Exp 5.4 just died on the wife tonight... She is NOT happy about that! Just did a battery one week ago. Tried to jump it with the SuperDuty and also tried to short the solenoid, same result.

If your alt brushes are worn, you might show intermittent charging, fooling you to think it's working okay.
I would also expect the new batt to show approx 12.8 volts or so without running. If its new and showing some loss, the batt is trying to feed the engine draw without being resupplied by the alt. if you can't jump the solenoid with that new batt, alternator/regulator is probably bad.

Thanks for the reply. I did not get chance to look at it last night. I will be able to play around with it Weds. Left it in the parking lot for now. I will check those things you mentioned. Battery and connections are good, alt and starter could be bad, they are originals with 120K on the truck. I will do the alt and starter tests and check for voltage drop to starter as well. Thanks again. I will post up what the problem ended up being.

sorry for the delay. Well I replaced the solenoid on the firewall and that seemed to fix the problem until the other day. She called and said it won't start. Told her to move the shifter through the gears and then it started so I am guessing the problem is the transmission position sensor or whatever that is called. Is it adjustable?

No the Digital Transmission Range Sensor (DTRS) itself is not adjustable, but the shifter cable going to it is.

could this cause an intermittent problem? There is also no OD now for some reason?

Hi All,
My problem ended up being the starter. I ran all the tests and they passed all the way down to the starter. Ford Reman installed and ready to go.
Thanks for the help.
