Check the big yellow wire coming from the ignition switch for power when in crank. No power = Ignition switch issue, if it has power, then everything in the column is fine

If it's got no power, jumper one of the big red wires to it and it should crank. (use a good size wire for a jumper)

The other thing is make sure the switch is "clocked" right, there's plastic teeth on it that need to be in the right position when installed, if you're a tooth out it could make it where you have to turn it hard to get it to crank but the rest of the positions of the key should feel kinda different as well.

the truck is not starting so we tried jumping it the starter turned, relay we swapped still wouldn’t start it seems when you get violent with the key in the ignition than you can get it to start, but I’ve been told it’s the actual barrel where the key goes in, I tried the ignition switch, nothing, if I boost the battery I can get it to start now that won’t work, so I’m at a loss might put a push button in it, it’s just a hunting truck
So if you boost it it works??


It's a bad battery or cable to starter-ground-under hood fuse block then

Too much voltage drop-loss

Modules are very suspecting to drop in voltage, and cause lots of issues with weak battery, even if it new means nothing lol

You haven't answered my question


Does it crank all the time, just once and while won't fire



Does not crank all the time, when key is turned,fires up with the battery charger on it though

Fuel pressure gauge will solve that one. It should throw a “too lean” code if it’s running with a bad pump.
