Need a little help! - Diesel Forum

Yesterday morning driving home from work I stopped at a red light and i noticed that my truck was missing. i drove it the one block to my house and let it idle while i looked at the codes with my outlook monitor. it had codes p0275,p2285. looked then up inside one is #5 cylinder balance power and the other is Injector control pressure senor circuit low. the miss would go away as soon as the engine rpm where increased. so i went to work last night and buy the time i arrived the truck was running like crap. i took it in the shop and looked at the codes again, this time there was p0263,p0269,p0275,p0360,p2285,u3560. # 1,3,5cylinders.
when i leave the truck running for about ten minutes it almost dies several times and has no power, it does not knock or make any noises just runs like crap. also noticed that the alternator was so hot that i almost burnt my hand on it! I unhooked the alt. has anyone ever heard of this before? I need a little help as i am 500 miles from home at work and need this truck to drive home in six days!

thanks in advance for any help

Had the hot alternator problem - Alternator was dying so I'm replacing it - same symptoms rough running unless I charged up the batteries on a charger - then ran smooth. I don't have a scanner (yet) so I can't help you with the codes - but from what I have read on this site. low battery/alt voltage screws with the electronics and injector firing - may be others can chime in with better advice - mine is - charge the batteries with a charger and see if the problem goes away - if it does - like mine did - you're looking at a new alternator.

GOOD LUCK !!! - lets us know how it turns out

So a replaced the alternator and all the electrical codes went away and changed the fuel filters. good thing? no,the truck starts and runs fine when cold but as soon as it warms up it run rough a little smoke out the exhaust has very low power. when you rev it up its a dog until about 1500 rpm then it takes off. i took it for a test drive around the block and when you get it over 1500 the thing has all the power that it had before. but if you let it come down to idle it will stall and not restart until the engine is cold again. then it will fire right up like there is nothing wrong. what the f--- is going on and in two days i need to drive 500 miles home with it can someone give me an idea of what to look at.

still getting the codes? probly and injector leaking compression into the fuel system.
