2013 model 210,000 miles I have been adding coolant for almost a year, just topping it off every few weeks. The past month ive had to top off every other day, truck ran fine and showed no signs of issues other than coolant getting low. Did multiple test with the coolant and the die and never showed head gasket leaking. i know i had a small leak from water pump during the last few weeks. I pull a trailer with a skid steer for work everyday and was in a bind finding alternate transportation to keep working. On the way back from a job I had just pulled off the interstate and when i came to a stop at the light i could smell oil and the truck shut off. I tried to restart and it was a slow crank no start. Engine temp was showing 210 on guage
I got the truck towed to my house, took off belt and tried to start it. It spun over normal but no start. Pulled the codes and every injector had a fault, ordered and installed pcm but no luck. I pulled the metering valve and no metal shavings, fuel looked clean. Did a compression test and all cylinders came back within spec. I have the truck at a friends backyard shop now so i work on it when i can. I thought this would be something catastrophic and pretty obvious ( and it probably is ) but havent been able to pinpoint my problem Ive read about cracked pistons and plan to do a leak down test next. Any input on diagnosis in the mean time?
thanks

Welcome to DieselPlace

Start by checking all fuses.
Grab a scanner and check for desired vs actual fuel pressures
If you still have the fuel filter head you might be sucking air past the o rings in the primer button.
while you have the scanner check for any stored codes

 

Ok, i wont be able to get back to the shop myself till this weekend. My buddy did start the truck this afternoon on ether and said it ran smooth. He's going to check fuel pressures and codes tonight

 

Update on my issue. Fuel pump went out, but did not grenade and send metal through the system. installed a pump and now have proper fuel pressure. Truck still will not start. It has 4 hard faults in it for the injector goups
P2146
P2149
P2152
P2155
We ordered a new pcm and installed with same results. No start and same set of codes.
All the injectors ohm'd between 182-183
The 3 wires supplying power to pcm through connector 1 (middle plug on the pcm) are good and have correct voltage
Main grounds have been checked
Ive read in some instances people replacing the pump and getting a no start because of air still present in the fuel system, but with those set of faults present that should be my main focus, correct?

What scanner or code reader are you using to get the information off your truck ?
