New to Diesel have some issues with 03 6.0
First and foremost let me hi to all here, I am new to this forum and to the diesel world in general. I picked up at auction a 2003 F250 Superduty Powerstroke pickup. While at the auction the truck was running at idle was in excellent shape, sounded good, no smoke, etc and it had 117000 miles on it. I won the bid and payed 6700 for the truck, I thought I hit a grand slam.
I drove the truck home from the auction and that's when I noticed the white smoke coming out. I first thought it was because there was only an eighth of a tank of fuel in it and the truck had probably been sitting for awhile. I filled it up, the truck started with no problems but the smoke was still coming out.
After running it for about a half hour the smoke quit as long as I was running at a high (60 to 75 mph) steady speed. Once I slowed down to below 60 the truck would start to run rough, missing to be correct, as long as the rpm's were up the truck ran pretty well.
I put a scanner to the truck and these are the following codes I recieved:
P0263 INJ Cylinder #1 contribution/balance Power cylinder, valve train or injector
P0562 PCED System voltage low Charging system failure
P0671 GPCM Cylinder 1 glow plug circuit Circuit open, short to ground, short to voltage, faulty glow plug
P0683 GPCM Glow plug control module to PCM communication circuit Open circuit, short to voltage, short to ground, faulty PCM
P1378 INJ Module FICM supply voltage circuit low Faulty connection, fuse, faulty relay, short to ground, charging system
Now I did forget to turn the interior dome light off, and it was on for a day and a half, so I am assuming that the low voltage codes can be due to a low battery.
My question is this, what do I need to do to check and what needs to be replaced? Looking for sugestions here on what you all might think the problem is. Thanks
Oh, the truck starts fine no problems, runs fine other than a bit rough at low speeds, like you are in overdrive at a low speed kind of rough.
