I think the computer is telling you that it is not recognizing what gear you are in as you can only start the vehicle in park or nuetral. thats the best i can do for you sorry

Prndl error on message center on my 2003 ford expedition. It won't turnover, start or crank. I hear a clicking noise in fuse box when I turn the key...HELP PLEASE...

Hello Shanique Reddick,

I had to star at your PRNDL word for a second
before I realized ... that is your
AUTOMATIC SHIFT Sequence letters...

I'd be wiggling the neutral safety switch around to see if there were any response there...

"NEUTRAL SAFETY switch is defective your car is ready for loco-motion (toto-cray = driverless possibilities)...

Get a sharp mechanic to TEST the switch...

PRNDL error nobackup aid is showing. Its not showing any mile to E nor milage on the dash. Also I had someone jump me for a little and it tried cranking up, it wasn't hooked up long. Does that mean it...

If you're finding it difficult to service/repair your car, get one of those
online manuals. You'll not have to wait for others to answer, or rely on mechanics and all. Plus i know a website that has very good manuals online, without expiry i.e. for lifetime.

My 03 Expedition will not start all of the lights and electronics work and climate control but will not turn over. It pops up PRNDL Error on the control panel. The battery is fine.

Hello, I went browsing and found your answer. I can tell what it is, but not exactly where it is. The problem is the PCM relay. I imagine it would be in one of the big Relay boxes under the hood.

This appears to be a common problem and diagnosing it can be done with a scanner. The error message is what throws mechanics off. Several people thought it was the neutral start switch and the actual PCM. There does not seem to be a reason for the part to fail all of a sudden.

Autozone ,Oreillys and some other parts places have photos of the parts and may be able to show you where this relay is. But at least you can call about availability and price before you go to get one.

Ford expediton 2003 would start try 10 min later start up by the light inside truck is'nt working, the gas, speedometer, backup aid, windows.

Either the fuse is bad, or the connection to fuse block is bad which is common, or lastly, a faulty ECM
