I have a 2002 F-150 XLT 4.6L that lost all power while driving down the highway last night. I have 3 warning lights on my dashboard. The Service Engine Soon light which is constant, the battery warning light, and the oil pressure warning light. My battery is fine and fully charged so I don't understand why the battery light went off. My oil and temperature are/were running normal when this occured so that doesn't make any sense to me. Is this a special code for something when all three go on other than go out and buy a new truck. When I pulled over and tried to restart the truck, it started and started shaking violently as if the truck wasn't getting gas, I immediately shut the truck off and towed the truck home. The truck has approx. a 101,000 miles. I have not replaced the spark plugs yet. I'm wondering if it might be a clogged fuel filter. I did replace the fuel filter around 50,000 miles. After towing the truck home, I tried to restart the truck but it wouldn't start. If anyone has any suggestions they would be greatly appreciated.
Thanks,
Eric

 

You need to get the codes read first.

 

Yeah, I plan on going to Autozone to get the codes off my truck tonight.
Thanks.

 

Holy Crap, you haven't changed your fuel filter in 50k miles? Way past due. Battery light could be your alternator is shot.

 

Perhaps it's something as mundane as running out of gas.

Those three lights are normal when the ignition is in RUN and the engine is not running. The battery light is supposed to be lit when the ignition is on but the battery is not charging.

FWIW, you probably won't get any useful fault codes, I wouldn't even bother going to AutoZone for that. You need to diagnose it as a "Cranks (presumably - you didn't say) but does not start" failure.

My speculation is a fuel delivery failure, but that's based only on your sketchy description.
