The service writer at the Acura dealer is a girl nothing against that at all but when I try to tell her what was checked etc. So the problem is a shot injector pump. The diesel engine requires a supply fuel line fuel from the tank to the engine and a return fuel line fuel from the engine back to the tank. About 3,000 miles ago, it started hiccupping while running, first only under hard throttle and then eventually all the time. We haven't found one mechanic who can figure out this problem.
If it swings much higher like say, 2 or 3 degrees, then you may have a problem with the gear train. Going through about a filter a month. So next day after doing a bunch of reading I started messing with it. Housing pressure partially controls injection timing. Good Luckso does this mean i have to take the intake off to run this jumper.
It can't see though air at all and doesn't deal well with water, bubbles or some fuel contaminants that make the fuel too dark. Given the trouble the stock vacuum pump system gives, one would assume the worst and think the pump is toast. Swapping it out is a simple 2 min job. Then you can further scroll down to code p0251. If you see a steady stream of any sized bubbles, you have a pinhole or other sized hole somewhere between the filter manager and the tank. The specifications will differ based on the year make and model of the vehicle. We are sending the core in for rebuilding to have a spare on the shelf all the time.
This test monitors the number of high resolution pulses which have been missed not detected. Lookup Diesel in the Yellow pages to find a local dealer. Upon starting it will not turn over, emits a heavy white smoke and sounds to be missing it can take up to 5 to 10 minutes to get it started, sound is like a bluh bluh bluh bluh, once it starts and clears it runs perfectly and will start perfectly for the rest of the day, but gives the same trouble the next morning. Fuel System Shutoff Solenoid This is what stops your engine when you shut it off. At idle, the desired injection pump timing reads 8. The high resolution is one of the most important inputs by the for fuel control and timing. Quick jabs at the pedal have similar results, along with stalling.
We see you haven't yet. Also called fuel solenoid driver. Another possible cause is the optical sensor filter harness. Looking forward to any input. As for replacement - I'd consider having a Stanadyne shop do the work. I think my luck has finnaly run out on this one. It always starts good and fast and the time it set the code was when I was leaving work.
You can either move it to the top of the intake manifold with a finned cover, lie was on mine originally, or the best is to use a 6' extension cable and relocate it to behind the front bumper, which is where most of us with the 6. Stuff grows in diesel and can plug things up pretty good. Seemed to quite down and run ok although i only moved it on the property. This reduces housing pressure to near zero, so that the transfer pump pressure behind the power advance piston can easily advance the cam ring. I did some checking, and my manual does not list a procedure for replacing the optical sensor. It has 155k miles and I was told it had the injection pump and pmd were replaced and pmd relocated. Avoid these unless it's been upgraded with the ceramic rollers - the metal rollers inside them will shred unless you run an additive 24x7.
Changed the oil batteries and flushed coolant and put it into full time service 3 weeks ago. How serious is the P0251 code? Scanned it with a reader. Trouble shooting: Low or no boost Error codes: Potential problems: turbo, clogged catalytic convertor, leaking vacuum lines, bad wastegate solenoid, bad vacuum pump In April, I attempted my first tow with the Suburban. The 17 volt problem must be something else, like you say. Getting a p0251 will generally give you something else paired with it.
After I read them the codes they explained that the optical sensor in the pump had failed. I had to give it the go pedal to get it to stop. Whether it would cause other problems besides the meter dispaly, hard to say without scrutinizing the electrical schematics. The lift pump down under near the drivers door seemed to be working fine as fuel would come out of the tee valve when opened under the hood and a amp meter said it was. No question, my solenoid was clogged or wore out. It's diesel coming from the injector pump. Use the T-27 bit and the snap ring pliers to remove the cover and free up the optical sensor upper half.
It had a intermittent check engine light for the crankshaft position sensor, a small diesel leak around the fuel filter where it screws down, the fuel gauge floats around and the volt meter reads 17. Injection Pump and Injectors An injection pump with stuck or defective advance mechanisms can cause the engine to smoke abnormally. When the air is eventually purged from the affected injector line, the cylinder will begin to fire and will produce white smoke for a short period of time. Which seems to be the main culprit in these situations. Use another screwdriver to hold the lock plate in place.
