Replaced IPR - Now 7.3L engine won't run ... HELP!!
1999 F250 - 7.3L Powerstroke
I just drove from Idaho out to Atlanta (where I have been stuck working on my truck on the street curb). On the way out, the engine started puking blue smoke really bad. It went through two gal of oil in the 1200 mile drive. I figured injectors or O-rings were toast. The trouble codes indicated injector and IPR issues, so I changed them out.
I changed out all eight injectors & glow plugs, as well as the injector harness and valve cover gaskets I then got the engine running, but it was still running rough and still puking a lot of blue smoke. I then changed out the IPR and started the engine again. It ran smooth for a minute without much smoke, but it then suddenly died and I have not been able to start the engine and keep it running since. Engine turns over fine and acts like it wants to start but it will not. I tried a little starting fluid in the intake to help it out some. With that, it would then start, but then quickly die again. I checked all of the electrical connections I had hooked up from the work and all appear good.
Current codes :
1316 (Injector Circuit/IDM Codes Detected)
0470 (Exhaust Back Pressure Sensor Circuit Malfunction)
I would appreciate any and all help and suggestions to help me get rolling again. Thanks!!
