truck wont start when i turn the key, starts with push button
Hi I just bought a 2000 f350 with 7.3L for some reason it has a push button start. figured the ignition switch was bad so I changed it and still the truck doesnt fire or role over while turning the key. i checked the wires under the dash and there doesn't seem to be any missing, cut, or disconnected. also the starter motor relay coil fuse and the instrument cluster and hi beam headlamp fuse doesn't have power to it. I have an edge juice programmer brand new in box that I also cant hook up because when I plug it in it says no connection made. Is there anyone who can help me with this. Im lost and live in a little town that has part changers not mechanics and they just tell me to track wires. oh and im also getting around 9 miles to the gallon

The starter relay coil fuse gets it's power from the Start output of the ignition switch. So that says that power isn't getting thru the ignition switch if you're checking with the key in start. That might be why the previous owner installed the pushbutton to the relay.
That fuse, #20 (15A) feeds thru the Transmission Range Switch (start only in park or neutral) and then to the starter relay.
The instrument cluster fuse #15 (5A) is the keep alive power for the instrument panel and should be hot at all times. It's fed by Fuse 22 (50A) in the underhood fuse box. The circuit runs thru connector #1049 (the top one of the three connectors going thru the firewall). That circuit being bad would also kill power to a bunch of other stuff in the under dash fuse box. Maybe the fuse box itself is corroded, causing the dead fuses. Windshield leaks can cause problems like that.
The high beam headlamp fuse #16 (15A) shouldn't be powered unless the light switch is on and the dimmer switch is set for high beams.
Where are you in Alaska? There are quite a few TDS members up here, and a lot are fairly familiar with these trucks.
ok so i got the key working again and got rid of the push start, tomorrow im going to check the obd11 again. i believe it will work after what i just fixed, im also going to check those fuses the way you are describing. im in wrangell ak.

Glad you're making progress on it. If you need more information just holler.

So I guess I probably won't be hopping in the truck to run over and help you troubleshoot it.
What? They don't have ferry service from the mainland? I didn't know Alaska went that far south. I learned something today...
Yeah, they have ferry service, but it's a full day's drive from my place to Haines to get on the ferry, then a 2 day ferry trip from there to Wrangell. Don't forget that Alaska stretches from Savanna, GA to North Dakota to LA if overlaid on the lower 48. It's BIG!!
Funny seeing the map I recall inlaws coming from NJ to visit us in LA. They always asked could we go to the Golden Gate or see Frisco tonight? To imagine it being an 8 hour drive was hard to grasp. We kept maps in the kitchen so they could compare just driving to Orlando Fl for Disney World when visiting them in NJ. I just wish I knew more hunters in Alaska needing a spotter for moose or......... Yes I would take that 20 hour drive.

so i got everything working and got the edge juice programmer in, it didnt seem to make a huge change. even on stage 5 performance, just doesnt seem to have any snap to it, i have banks 4inch with down pipe, edge chip, and airaid cold air intake, and im only getting like 9 miles to the gallon, any suggestions on any of this. i want to get some more snap out of this thing and or better fuel.
well you havent mentioned how many miles are on it...is it lifted?size of tires?also mpg is definately affected by your right foot.having the edge on the performance setting is not good for mpg.my truck is lightly modded and i drive it easy,,, i get 15 mpg in town,,,but again all u to your right foot.
