Hey guys, need a little help here. Wife drives our 99 expedition, 4.6 engine. She just called and said she turned a corner about 2 miles from our house and the truck died, check engine light came on. Also said it wasn't shifting right and wouldn't go into 3rd gear. she was able to let off the gas pedal to get it to shift until she turned, when it just dropped in its tracks. If it was my old truck I'd replace the module and be on my way, whats the suggestions for this? Thanks for all the help.
Should also say the starter turns it over but no fire.

 

When you turn the key to the run position. Do you hear a fuel pump whine, you have to listen closely. Let us know.

 

Try this...The fuel pump reset switch. I had a friend who was just driving along hit a bump in the road and it tripped the fuel pump cut off. I drove 40 minutes to get to him and after sitting there stumped for a good hour, I checked and sure enough......not much but maybe..........

 

Heres an update, Wife got home from work so I quizzed some more. She said when she left the driveway today it had no power, really doggy. she got two miles on the gravel roads until she had to turn towards town, when she turned the corner, it died off and was done. A friend and I drug it home tonight and into my shop. Checked the fuel pump shutoff-ok, checked all the fuses that said anything to do with fuel-all ok. hooked up timing light to plug wires--all were firing. I turned the key to run and tried to listen for a fuel pump but couldn't hear anything. There should be a pump in the tank right? Now its been acting funny shifting for a couple months, but that seems unrelated. But who knows what the computers in these control anymore. Thanks for the suggestions, shes content driving my old blue truck (see the signature) to work this week while I mess with hers. I'm sure she would rather drive my 00 superduty, but I have farther to drive to work, not to mention the gas I save not driving my 79.

 

try the fuel pump relay fuse before you go onto the fuel pump, yes the fuel pump is in the rear. try the fuel filter also and then the pump. sometimes the relay will not totally burn out and sputter for a little while.

 

You said the check engine light came on right? Get the codes pulled to aid in your troubleshooting.

 

OK guys, we'll bring this around and close it up. fuel pump. I didn't need to pull any codes, hook it up to an analyzer, nothing. It was simple internal combustion troubleshooting, all you need is fuel, air, spark, if one is missing, your engine won't run. I think a lot of people nowadays lose track of the simple things when something goes wrong.

 

Wife fixed?

Good luck with that one!

 

Well we really fixed it now. On a recent trip, the tranny started kicking out of gear, worse than has already been happening. Traded in the 99 for an 03 expedition. WOW very nice, I'm pretty sure I won't get hassled to drive my super duty anywhere or to "trade" her trucks.
