Need Help Fast Truck Wont Start
 

So I just got home n left truck running grab some cloths jumped back in went 15 feet and the truck died so I bumped the key air dog will only kick on for 2 seconds n then quit. I have 2 codes p1698 n p0562 I'm lost so any help would be nice thanks

P1689 - No Communication Between ECM and Injection Pump Module Data link circuit failure between ECM and fuel injection pump. Low power, engine derated, or engine stops.

P0562 - Charging system voltage too low

For the p1689 check your fuel pump relay it could be bad. U could go to advance/autozone or which automotive store is closest and get a new relay and try it before suspecting its the vp44 or ecm. Hope this helps bud

Anybody else have any idea whats wrong with it.

Did you check all your relays and/or fuses? Seems to me like and electrical issue...

Well I talked to dodge dealership n they said it's the crank shaft sensor which makes since I dont see any rpms when it turns over

I had the same thing happen to me. I was at the store and went to start the truck up and it wouldnt turn over waited alittle while an it fired right up. Alittle ways down the road I lost my rpm guage and then it came back in bout 30 seconds. I also changed the crank shaft sensor and never had a problem since or atleast until the electronics went out on the vp.

I have rpms when it runs but nothing when i crank it over I should see 2 hundred rpms when i crank it over

The Crank sensor shouldn't effect the AirDog running for such a short time though. ECM fuse perhaps, or the connections on the backside of that fuse.

Where is that fuse at

Inside the cab, far left side of the dash. Door has to be open to access it. #6, I believe.
