Western Branch Diesel Charleston Wv
Try using Stanadyne Performance formula fuel additive; this will often solve a "dies on deceleration" problem after just a short drive. If the engine does not start. Removing the PMD requires a T15 torx bit.
Diesel fuel is combustible. Either the sensor or wiring is defective. IF the smoke is mainly when the engine is cold, make sure the cold advance solenoid in the injection pump is receiving power until the engine reaches approximately 120 degrees coolant temperature. Perform a careful check of the suspected circuit for the following: Inspect and ensure the integrity of all related wiring harness connectors. This is a good idea if you live in a cold or rainy state. At this point I've pressed the priming pump an uncountable number of times, re-seated the filter, o-rings, and WIF sensor. Refer to local and state laws that pertain to the discarding of used diesel and used fuel filters. Then you just have to try to start the engine. Low engine compression will cause white smoke. If you are in this position, take the vehicle to your dealer or a good mechanic. How to Start a Diesel When It’s Out of Fuel. In the event I run my '03 4x4 Dmax out of diesel, what is the procedure for repriming? Install special tool J44638 to check vacuum restriction on fuel supply to the high pressure pump.
These motors can lose their prime for a variety of reasons. 02 degrees when doing TDC offset learn, or this code will set. In some diesel engines, priming the fuel pump can be as simple as turning the ignition key to "run" for several seconds, turning off, and then repeating up to four times. Check vacuum at the wastegate actuator connection on the turbo.
The EGR flow calculation on some models uses the MAF sensor. Add up all recorded measurements to determine total injector return volume. How to prime a duramax after running out of fuel lines. If the return volume is less than 144 ml for all 8 injectors, refer to the high pressure pump test. Not every problem will be major and sometimes you just have to buy a new filter cap to solve it. This is a preliminary test to checking the fuel return rates on the following pages. Ignition off for 60 seconds. Crank the engine for 15 seconds and measure the fuel from the regulator.
Prime the new fuel filter by pushing in on the black primer cap on top of the fuel filter until the diesel starts to run out of the relief valve. Also, aftermarket modifications can contribute to this common problem. A large leak means there is a leak in the high pressure system. Buy Racor Fuel Filter Head Assembly. Individuals often make the mistake of cranking the engine in an attempt to prime the pump, which can wear down your battery and, in some cases, fail to recirculate your fuel. 6 Fuel Pressure Regulator. When driving under hard acceleration, maximum would be 7–8 inches Hg. For the most part, the long-existing information and procedures on handling a fuel-starved diesel engine are still plenty viable. Chevrolet-GMC Diesel Diagnostics. The turbo needs to be replaced. In some cases the "Filter Life Indicator" will be triggered prematurely, sometimes within 1000–5000 miles after changing the fuel filter. P244B DPF Differential Pressure Too High. If fuel pressure regulator 2 is leaking, the actual pressure will be at least 690 KPa/100 PSI below the desired fuel pressure. This light may come on when after starting the engine in extremely cold temperatures and driving at about 60 mph or higher. If an injector is leaking excessively into the return, the balance rates are often at the edge of specification.
Pressure is maintained via a "Constant Pressure Regulator" at 4-11 BAR (58-160 PSI). Water in the reductant tank will cause this DTC to set. Remove the high pressure regulator from the high pressure pump and check for metal debris. If it is oil smoke; how many miles per quart of oil burned? Diesel exhaust fluid (DEF), AKA reductant or urea, is injected into the exhaust gases prior to entering the SCR (selective catalyst reduction) stage. Another p[art to check would be the injection pump. How to prime a duramax after running out of fuel tank. Over time, the DPF will become "ash loaded" and need replaced or cleaned. Make sure not to crank the engine until you bleed all the air out of the system. The high pressure seal on the pressure control valve is one time use.
Note: Plastic bleeder screws are very prone to cracking. Then go and turn the key and crank her up, it may sputter and cut off again becaue there might be air in the lines still. Loosen your bleeder screw on your fuel filter housing and push the primer until fuel shoots out then tighten. How to prime a duramax after running out of fuel rods. EGR coolers commonly will plug up and cause this code to set. 9 are a possible cause for rough run. Running the engine above 1700 RPM switches the fuel pressure control mode to fuel pressure regulator 1. But it also has a primer button on top of the fuel filter housing. The supply pump operates during cranking and after the engine oil pressure comes up. Idle for a few minutes and.
The pump has to be partially disassembled parts replaced and then tested on the test stand. However, pressure lower than this range is its own problem, and you should still perform the return rate test to see if the low pressure is caused by one or more injectors dumping fuel. Remove the CKP sensor and attempt to move the reluctor wheel front to back or side to side with a probe. See Hard Start/No Start above. A bad Fuel control Solenoid (part of the injection pump) can cause the same symptoms and codes. One of those maintenance work was replacing a new Mann filter with an AC Delco option and the pressure returned to normal. Sometimes, it's as simple as adding more fuel to your tank and restarting the engine. Locate the fuel filter priming. Do Not use the starter to turn the engine over when the injection pump is removed, or when turning the engine to torque/remove the injection pump drive bolts. The injectors are cooled by a calibrated amount of fuel flow through the injector body to the injector return lines. Out of fuel, restart procedures. 5 Diesel, or Buy a DS4 Injection Pump for 6. Replace the heat transfer pad and use snap ring pliers to remove the calibration resistor. Inspect the engine coolant temperature (ECT) sensor. Use vacuum gauge, check the suction, you should have no more than 5 inches Hg at WOT (wide open throttle) or 7–8 inches Hg under load.
Loosen one injection line and plug in/unplug the shutoff solenoid a few times until you get fuel out the line, then tighten that line and go to the next injection and repeat to be sure there is not an airlock. Proper bleeding procedure for a Duramax Diesel of ALL year models..... Note; multiple codes can set for just one fault, as if the other codes wanted to come to the party. P0101 MAF Sensor Performance. They should read ambient. If the DPF has been deleted, customers will have run-ability issues if they do not have the correct software. Excessive restriction could also cause a DTC P1093 to set at the same time. If the calculated flow is high, the ECM assumes a larger quantity of fuel has been filtered. See GM service information. An EGR cooler that is leaking internally can cause white coolant smoke, often after sitting overnight or for several hours during the day.
