Nov 20, 2018. #2. Fuel injectors should last the life of the vehicle. About the only issue I’ve had with them on a different brand of vehicle is chemically dirty fuel that passes through the filter which gummed up the injectors themselves causing the service lamp to light up. No such luck. He kept her for two days, drove her, let her run, started, stopped, nothing. I finally decided that we had to start somewhere, and with 200K+ on her, a fuel pump was a good starting place. When I was stuck on the freeway, there was so much noise that I could not determine if the fuel pump was running or not. Dealer called on Monday, confirmed metal in fuel system, HPFP failure. Total repair took about 9 days, half of that waiting on the results of a fuel test. Covered under powertrain warranty, dealer quoted ~$6,200 for an out-of-pocket repair. Will spend up to one hour to attempt diagnosis of customers complaint. . We won’t go into details regarding the differences, but we will tell you the most common diesel fuel pump failure symptoms as well as diesel fuel pump failure causes. Lets Take A Look At Four Of The Most Common Symptoms Of Pump Failure 1. Engine splutter. The earliest diesel fuel pump problem is foretold by an engine sputter, particularly at. Very possible that it's flooding, and that pumping the gas gave it more air to compensate by opening the throttle plate. And that's why it would take 45 minutes for it all to evaporate before it would start. Flooding vs fuel starvation should be easy to tell, by removing the air cleaner lid and smelling for gas. If none, starvation. Is this a known mode of fuel pump failure (ie intermittent) or should I look in the control circuits? Can somebody explain what goes on in the control circuit? After the initial whoosh does the supply to the pump get turned off by the relay?. 4. Backfires. Since a bad fuel pump can give an intermittent amount of fuel to the engine, you can experience misfires because of the too low fuel amount. The engine can also get too much fuel, resulting in unburned fuel in. Intermittent failure to start. Tags failure intermittent start. Jump to Latest Follow 1 - 6 of 6 Posts. J. jampa · Registered.

I would suspect that if you have trash in the tank and the pickup is clogged somewhat you are putting starin on the pump. Could also be caused by an electrical problem. Had a chronic rough start condition, found that with the key off fuel pressure dropped to zero rapidly. added an in-line check valve and ever since have intermittent failure to start, even after replacing the whole pump. wiring connector is supposedly o.k. What causes this? Well a couple things could. Might be the pump but usually they fail and are done. They do not come back after failure. The most common is the fuse panel from overheating of the connections. I would look very closely to. The best method of telling fuel problems from ignition problems is to check for spark by pulling the wire from the center of the distributor and holding it with rubber gloves a quarter-inch from a good ground while you crank the engine. If there’s no spark, it’s an ignition problem. If there’s spark, remove the air cleaner, open the. During this time voltage is sent to your fuel pump and it spins for a quick moment. On a cold day, with thicker than usual fuel, causes inadequate fuel pressure on the fuel rails and therefore injectors. Causes the motor to crank over and over but not start. Fix: Let your key rest on the ON section for a few seconds. Works for me everytime. - Turned it off, came back 10 minutes later - fuel pump not running. It was towed to a Subaru dealer. They replaced the fuel pump and also the fuel pump controller which they apparently damaged in the process. This took a week. Three days back on the road and same problem again. No sequence to it. Turn it off, start - OK. Turn it off, start. Fuel pump not priming and the fuel pump error code is thrown. Battery was charged overnight and same error code and she officially The intermittent nature of the issues made it very hard to diagnose especially since it ran well in between. Intermittent fuel pump failure warning on 2011 BMW 328xi Last week my car stalled on the side of the highway after throwing a fuel pump failure warning. I ended up having it towed, although it did start for me once or twice in the hour I was waiting, but. Anybody have any problems with their intercooler pump. Check engine light came today. When I checked codes I get intercooler pump open circuit. Checked fuse and it's good so I believe it is the pump. Just looking to see if anyone else. class="scs_arw" tabindex="0" title=Explore this page aria-label="Show more">. A faulty fuel pump relay prevents your engine from running as the fuel is not supplied. There are many signs of a bad fuel pump relay including loss of power, engine not starting, pump not making the common noise, and vehicle getting on fire. While all listed signs could happen due to many other issues in your vehicle, the fuel pump relay might. Agree. The design of the new pump seems to need greater lubricity than the current diesel fuel can supply in a large number of cases. Both Ford and GM had issues with the CP4 pump. What I was trying to tell the OP is that when he gats the truck back adding a lubricity improver to the fuel may help over come the shortcomings of the CP4 pump. Please help! Every 100-300 miles, my 2010 535i dies and throws a message on the screen saying "Fuel Pump". (see attached pic) It usually starts back up after waiting 10 minutes to sometimes 45 minutes. Took it to a shop and they said the low pressure fuel pump is the culprit and $1200 later, it. Mid May '17 -15 minute drive to gas station, fill up with flex, car cranks and cranks, no start. Unhook the batt for 15 minutes, still wont start. I can hear the fuel pump relay activate and the pumps running. Unhook the batt again and call a tow truck...30 minutes later and no tow truck I say eff it and try one more time, it starts. </span>. 2AAE - Fuel pump, Intermittent; A diagnostic scanner that is capable of reading, clearing, and performing bi-directional tests on BMW vehicles. You must verify that the scanner that you use supports your BMW model and year. Full system scanners known to work on BMW vehicles can range from $150 to $800. I have an intermittent no-start (turns over properly - no start) issue due to the fuel pump not engaging upon switching the ignition to position II. 1. MB Star System shows NO FAULTS. 2. On random occasion the engine turns over properly but no start. 3. Two of the most common causes of diesel fuel pump failure are consistently low gasoline and engine breakdowns. Your vehicle should never run out of gasoline—keeping appropriate fuel levels will make sure your vehicle functions as it should and prevents your fuel pump from having to deal with an unnecessary amount of strain. On my wiring diagrams (K1 750 and K6 750) it shows power coming from a fuse through the relay to the pump. If you have power coming OUT of the relay (make sure its the correct wire) then there is a broken connection between the relay and the pump connector. Its not a direct shot from the relay to the connector though, as that relay powers other. I could easily absorb the fuel pump failure -- stuff happens with cars. I could even absorb the fuel line deterioration as the cause of the fuel pump failure. But if fuel lines are vulnerable, then you treat them like brake pads and air filters: you design them to be changed every 50 or 75 or 90 thousand miles so they don't wear out. Sputtering Engine. Your fuel pump is telling you something if your engine starts to sputter once you’ve hit the top speed on the highway. The sputters indicate that your engine is being starved of necessary fuel, and starvation could be caused by a clogged or failing fuel pump. Sputters also indicate spark plug trouble. Fuel pumps are known for intermittent failure when at end of life. 200k miles on the original fuel pump does seem reasonable for replacement time. It's hard to verify this for sure since you'd have to get a fuel pressure reading when it's acting. Bad ground – The fuel pump relay is to be grounded properly. If this happens, the contacts will have a problem and may work intermittently. Contacts – Unlike other relays, the contacts in a fuel pump relay wear down over time which can cause problems with turning on and off of the pump.; coil – This is somewhat similar to a spark coil which gets weak over time and causes problems. Other factors like corroded contacts, compromised wiring and failing solenoids can cause stress to the TIPM power and ground control circuits. A weak battery or poor charging system can also cause problems. Like any computer module, prolonged unstable voltage conditions can cause the TIPM to fail. Fuel pump failure warning. Thanks for providing your experience. Helps me when discussing it with the dealer. fuel pump failure, when riding and before start. just wanted to add a symptom, when you turn on the No/intermittent liquid fuel causes fluctuating fuel pressure, loss of power, overheating. This 100% eliminated any other issues other than the fuel pump. The mercruiser mag mpi 350 has 2 pumps. One in the fuel cooler (high pressure) and the priming pump (low pressure) at the fuel water seperator. Im guessing the issue is with the high pressure, considering there is no issue at idle or in neutral; only under load and 3k+ rpms. Intermittent fuel pump failure warning on 2011 BMW 328xi Last week my car stalled on the side of the highway after throwing a fuel pump failure warning. I ended up having it towed, although it did start for me once or twice in the hour I was waiting, but. Do low fuel pressure diagnostic trouble codes exist indicating a performance issue related to fuel pressure (SPN 94) Is the pump is receiving 9 volts or more at pin 4 and pin 6 (see below) Does fuel inlet restriction exceed 8.14" Hg. / -4 psi, causing the pump to draw too much current and shut off or behave erratically (this could be cause by an intermittent fuel. CP4 High Pressure Fuel Pump Failure. CLICK HERE to purchase our LML CP4 High Pressure Fuel Pump Failure Kit. The 2011-2016 Duramax suffers from a high pressure fuel pump issue unique to this year range. Failure of this CP4 pump is usually catastrophic, causing instant contamination of the entire fuel system with metal particulates. No need to change a fuel pump . You will have to go back to the power distribution center and verify that current is ACTUALLY flowing from fuse , to relay to fuel pump harness . Obviously , current is not making to fuel pump harness at tank or engine would start . Use a computer safe test light ( so you don't spike any wiring to computer) and. Fuel pump not priming and the fuel pump error code is thrown. Battery was charged overnight and same error code and she officially The intermittent nature of the issues made it very hard to diagnose especially since it ran well in between. . Bad fuel Supply pump will normally cause this code. 2. Could also cause a DTC P0216. 3. Could set due to excessive cranking, see hard start diagnostics. DTC P0251 – Fuel Injection Pump Mechanical Failure, fuel valve feedback circuit . 1. If the engine still runs, check for fry grease, too thick of fuel can cause this code to set when the fuel. Join Date: May 2011. Location: OBX, NC and Obamaville. Posts: 6,780. Good to hear you fixed the problem. The only two possible signs of future pump failure from other members have been a long crank time and when going up an incline on a freeway, etc, the 4runner dies or throws a misfire code due to a lack of fuel. Causes of Fuel Pump Failure. The original Chevy pump motor has a life expectancy of about 15-20 years. Running the vehicle out of fuel, which will actually run the pump in a dry state can shorten the expected life span. Gasoline is a petroleum product and lubricates the inside of the fuel pump, impeller and other moving parts.
