No start ?

My 2017 will crank but wont start it started bucking and running poor. i got acouple codes p21d3 cleared it and then i got p31d1 injectors but i don't know if that's it it wont run at all any ideas i inspected the wiring looks good.

 

How many miles on the plugs?

 

77k

 

Make sure the plugs are at least tight and something about checking the injector fuse isn’t blown. Sorry that’s all I’ve got. Maybe @Dm93 has a clue. Good luck. Edit: check under the engine cover for rodent activity, too

 

Tks

 

Has the truck been sitting for awhile? If so, definitely check for rodent chewed wires under the hood.

If that is the case, sometimes insurance will cover the repair.

 

You may have to remove airbox cover to look for nests.

 

Welcome to TW!

 

Let us know if/what/etc the issue was.

 

I dont see any signs while back i had to replace the connector to the cam position sensor one wire was broke but didnt look chewed up

 

You are off to a good start here, you posted "it cranks but wont start" we know what you are telling us
so many here post "It rolls over" what the hell does that even mean
posters here will know what i am talking about.
Keep us up dated.

 

I would start by looking for any noticeable rodent damage around the harnesses. If all looks ok, especially around cylinder 5. I’d pull the plug on cylinder 5 and see how it looks

 

would one cyl stop it from runing it doesnt even attempt ?

 

It seems im getting the same fault code for different injectors. cant find any damage to the wiring.

 

Might try disconnecting the battery for a few minutes. Shot in the dark but i would at least try, IMO
