Slow Deceleration If the engine hangs at higher rpm or is slow to decelerate, injector wear is what normally causes this problem due to excessive return. If there are holes plugged in the nozzles, find and fix the cause before replacing them if the problem is in the pump, the replacement nozzles will soon plug as well. If the vehicle is equipped with an aftermarket supply pump system, be aware that there may be an inline fuel filter in the fuel supply line prior to the supply pump. Sometimes they fall down into the fender compartment. The Dodge Ram 1500 is a large and powerful truck. If the smoke clears in less than 1 minute, this would be normal depending on temperature and altitude. In order to maintain good fuel flow, especially with performance modifications, you may need to add an aftermarket supply pump.
Cap off the rail one line at a time cap is tool number 9864 to pinpoint injector. If the galley pressure is good see overflow valve and supply pump try the following on a cold start. A clogged filter can restrict fuel flow to the point the engine literally starves for fuel and smothers out. We recommend replacing the valve because cleaning is not always a successful repair. Odds are the lift pump, located below the filter, is toast. Give the pump time to cool for a couple of mintues between cranks. Look at solving the codes first.
Dodge uses a lift pump to carry fuel to the the injection pump, is it working? If the pressure goes to 50 psi or above the overflow valve will need to be replaced. To accurately measure boost pressure you must have the engine under load, such as full throttle acceleration while driving. Also might have left my fog lights on for one night. I have a1997 Dodge Ram 1500 with a 5. It seems like it starts fine next couple of times, if its not left for longer than about 30 min. Solve these problems first, before replacing the turbo. This process is easier with two people, one to crank and the other to watch for fuel and tighten the injectors once it starts.
So in case this happens to you, always check the wires. High pressure fuel entering your bloodstream may result in amputation or loss of life. Continued driving, when the fuel is under a vacuum, can cause cavitation, which will damage the injection pump. . The exhaust may need disconnected or a test pipe temporarily installed to diagnose smoking issues. If not then you have a bad supply pump, restricted fuel supply fuel heater screen or tank sock or the fuel heater is sucking air. If it takes longer than 7 seconds to clear up the smoke and rough run you may need to check the pump to engine timing.
Im getting power to the injection pump injection pump was changed when i bought the truck two months ago ,and after cranking i can hear the lift pump running for 20-25sec as expected as normal operation. After cranking over for a bit, pull a spark plug and see is it dry or wet. The heater will continue to cycle after the starting for a short time. This can be caused by either a mechanical failure or electrical failure. Do you get an engine light when this trouble happens? If you have checked the fuel galley pressure and it is good, then you can try the following; after the vehicle sits overnight start the engine and as soon as the oil pressure gauge starts to move increase the to 1800 rpm.
No smoke from the tailpipe after about 10 seconds of cranking means no fuel is getting into the cylinders. Then the transmission didn't want to change into 2nd gear. Your Cummins is electronically controlled so oil condition is important, fuel leaks, oil leaks, leaks in the air ducting between the turbo and the intake, sensors, water in the fuel. If the injector connector tubes, where they seat into the injectors, leak or the check ball in the injector is leaking or the high pressure limit valve then it will not build enough rail pressure to start the engine. If not, repair as necessary.
Excess idle time could be defined as leaving the pick up running while hooking up a trailer. Solve these problems first, before replacing the turbocharger. This causes the advance piston to stick in the advance housing bore due to cavitation damage. If not then you are looking at a possible pump or engine problem on that cylinder. Dodge Diesel Diagnostics 2013 — 2017 6.
See the for cleaning instructions and typical resistance values. Whenever i start up my car theabs and esp light turn on and when i try driving it doesnt go over 30 mph even. I jump started it with spare battery, It went fine, did not do much driving. Blue white smoke that burns your eyes, is unburnt fuel, cold temperatures, high altitude and excessive idle time all mean cold combustion. Over the years, there have been several reasons why the Ram has been recalled that may explain why yours doesn't start as it should. If it's dry, the computer isn't placing it into cold start mode to fire it up. A leak will often look like a fog or haze of fuel.
Pour some raw gas on the air filter element and make it wet, put the breather cover back on, and crank it over. So always make sure you start up your vehicles so these little guys won't make it their home. The fuel pressure regulator fuel control actuator in the high pressure pump controls rail pressure. It is difficult to reach, so enlist help from someone with small arms. That is what happened to mine, replaced it and ran like new again. Do Not use you fingers to find leaks! May 31, 2009 Check the fuel pressure at the filter. I hadn't used this one in a month as I have more than one vehicle.
If they leak externally, they are also leaking at the injector connection. I went to the dealer and they did a bunch of diagnostics and they replaced my fuel pump. This knob could also leak by the left front corner of the cab. The variable sleeve and actuator linkage also wear and carbon up, causing erratic movement and premature actuator failure. Also, if the sensor was recently replaced, make sure it is plumbed properly. Cap off the rail one line at a time cap is tool 9011 to pinpoint injector. When injectors are going bad, they can cause many different intermittent problems, such as: no start, hard start, black smoke, low power, white smoke and rough running.
