truck has been starting a touch slow and died yesterday backing out of my driveway. Primed fuel system and still won't start....

It threw these three codes:

P0207
P0700
P2146

Any suggestions would be appreciated! - Thanks

Mine did the same ended up had to put in new injectors, runs fine now, old injectors were plugged and pump could not create enough pressure when cranking to overcome

Before you go too far in pursuing the codes, unplug the juice and see if that fixes the no start problem.

As mentioned earlier, disconnect edge return to stock and try it. Check for bent pins in the bails and while your at it look at the injector wiring for abrasions or loose connections...looks like some malfunctioning injector controls---might want to pull the dipstick too and check for fuel in the oilpan.

That P0700 is tranny slip, it may have been there from earlier on likely not related to the no start...been playin on level 5 at all?

removed the edge as suggested. Looked around for bent pin and bad wires. Didn't find any!! No signs or smells of fuel on the dipstick. Oil level still at full! Can't see all the wiring but looks ok and still not starting.

Any more suggestions before I make the call to the dealer?

Think I need to remove the AFE Stage2 air filter before it goes to the dealer?? thanks for the responses.....

Also the edge is usually at 1 or 2 and never above 3 - thanks

Okay, check fuses in the underhood and dask panel (ECM / Fuel / controls, etc). Have a look at the fuse map on the lids for locations.

One thing about Diesels, No fuel - No start. Something is either not powered up or malfunctioning (CP3 / injector controls as per codes) or its out of fuel. Crack the bleeder screw pump till good flow comes out of it, tighten it up and have someone prime it while cranking.

If it dont go, its more than the simple stuff we can suggest to look for.

Good luck

How many miles does your truck have on it? and was this the 1st set of injectors.

Glad your up and running.
