Question about 2006 Chevrolet Silverado 2500HD 2WD

2 Answers

2004 duramax my diesel has no power and won't run (bucks) at anything over 2000 rpm, Idles and starts fine just can't accelerate. This started the day after I filled the tank up so I siphoned out all the fuel and replaced with different fuel seemd a better for about a 50 mile trip then started acting up again. Any help would be appreciated.

Engine sputters accelerating


no year? no engine? GC ,, . (crd 56?)

there are many engines, used, so we cant guess that.... and is totally Germain.
here ill tick off a few, for low power, and there are many simple tests.
  1. a tuneup, do the 60,000 mile listed tuneup now. Bam, runs.
  2. low compression on any cylinder. or all.
  3. bad spark (see tuneup)
  4. if 1996 and newer, scan it , in USA scan the ECU/PCM.
  5. bad fueling? too little or too much.

this is engine power, we need the year, the cylinder count and displacement. of said engine.
here is a shop manual.. 93-2004 years

Ran out of diesel now vehicle won't start


This is not unusual on a diesel. What happens is there is air in the system. If this vehicle has an electric fuel pump loosen line where fuel enters injection pump then turn ignition key to the on position and watch for fuel to appear and then quickly tighten line before turning off key. Then try to start. If does not have electric fuel pump will need a second person. One will loosen line and watch while other cranks vehicle until you get fuel and tighten line before the other person releases ignition switch unless vehicle starts first. If that doesn't do the job do this where line hooks onto each injector. Probably will not have to do this to all injectors but could run rough until all the air gets out of everything. I have farmed with diesel tractor for 25 years and dad I drove the gm vehicles with the 5.7. You normally don't start a diesel without bleeding the air out of the lines although some will self bleed most won't. Hope this does the trick.

I have a 2004 dodge stratus 2.7l next generation motor that has trouble starting but when it starts it idles smooth.Driving it the motor won't go past 2250 rpm.Change all but IAC sensor .Bought new...


sounds like to me the catalatic converter is plugged up, usually if you cant get an engine to rev anything over 2000 2500 rpms it has a breathing problem... its a real good possiblity its the converter causing your problem, especially if you had problems with another engine at any time, with like antifreeze issues, or fuel issues.. it goes strait to the exhaust and out the tail pipe.
hope this helps

The oil pressure gauge in my 2002 Duramax Diesel engine PU increases during acceleration and returns to normal following acceleration. Why would this happen?


That is normal. As you accelerate and rpm's increase the oil pump rpm increases. I think the oil pump runs 1 to 1 or 2 to 1 with the crankshaft rpm. Check the oil and inspect for any visual leaks if the gauge does not operate like that consistently. If it is intermittent or it just started acting that way, the sender my be bad. Other than that any Chevy Dealer will say that is normal.

Power Loss


My guess is injectors. The early duramax's had a lot of injector problems. They sometimes get to where they bleed constantly, and sometimes they break off... bad stuff. Check your oil for diesel. When my dads injectors when out on his 01 D'Max, his truck would run ok for a while, then lose power. Computer will cut power when it picks up an injector problem. BTW, Sightseer, diesels dont have spark plugs, however, the diesel filter is a good idea, you have to change them pretty regularly on the D'Max engines ( in order to try and prolong the injectors lives, mainly, the smallest bit of junk in your fuel can screw those early injectors up quick) I think they got the injectors mostly straightened out in the 04 models, what I've heard is thats the best model Duramax there has been, fuel economy, power, and reliability. Too bad all the year models arent that way :/
