Why is no start 2010 MaxxForce DT not working?

Why is no start 2010 MaxxForce DT not working?

First, engine oil runs the high pressure side. Make sure you have oil in it. Then, for what ever reason it cannot build high pressure. Either there is a massive leak, pump failure, IPR failure or simple ICP sensor failure. Most common are the connector right at the IPR. There are updates for it.

What causes a MaxxForce car to not start?

Verify with MaxxForce software or a mechanical gauge what your oil pressure is. Also I found a TSI on the International ISIS website for a hard start no start issue stating this could be caused by using NAPA filter 3994, FIL3994 or the wix and car quest versions. The problems with these filters are the are causing a low fuel pressure issue.

What causes low fuel pressure on a MaxxForce 9?

The problems with these filters are the are causing a low fuel pressure issue. If you engine is a MaxxForce 9, the oil pressure regulator is on top of the oil filter housing. What codes do you have? What codes do you have?

Why does my MaxxForce DT start when cold?

Usually when the base engine oil pressure ( Lube oil pressure) is low it usually causes issues starting when cold .

What to do if your MaxxForce 13 craking but no start?

Verify that the VSS (Vehicle Speed Sensor) is reading smoothly. If the code sets while in motion or during the creep test, replace the VSS. If the code does not set, a case file needs to be submitted to Navistar because the flow chart diagnostics does not continue after that step. There are a lot of extra steps in the diagnostic procedure.

What is the FMI code for MaxxForce 13?

SPN 731, FMI 18 knock detected, unexpected fueling without demand. i clear trouble code and it is come off, truck work normal.

What is SPN 731 code on MaxxForce 13?

It’s the dreaded SPN 731 code but is the FMI 18 or FMI 16. Two different paths for diagnostics depending on the exact fault. You can start blindly throwing parts at it if you want but I doubt you’ll fix it without doing the diagnostics.

Why is my MaxxForce crank but no start?

I also heard that using cheap fuel filters causes issues. They are all expensive and hard to find American made filters. Foreign made junk should cost end users less but it usually cost you more in other areas. Like a cheap air filter that a contractor installed. It somehow got rain water intrusion and sucked part of the filter into the engine.

Why does my Maxxforce Engine have a low power tip?

The main cause of this is a plugged up engine crankcase breather. A service kit is available for the MaxxForce DT diesel engines that allows mechanics to disassemble the low pressure and high pressure turbocharger on the compressor side (intake) and remove the soot buildup.

Can a MaxxForce DT diesel engine have no codes?

If a Maxxforce DT diesel engine in our fleet experiences low power with no codes we will be pursuing the same areas we looked at for this fix. As a matter of fact there is another bus in our fleet with similar problems. Experience has paid off once again.

Where is the ICP on a MaxxForce DT?


How to check for air leaks in MaxxForce?

Check for leaks and then a good*****test is recommended to make sure the rail is bled thoroughly of all the air .

Can a oil rail be replaced on a MaxxForce?

It is a two wire connector on it . You can if you want to but The real problem will be under the valve cover . The oil rail is leaking through the seals . The Ipr valve can also be replaced as I know they have made changes to it over the years as well to improve the design. Ok I have already replaced the seals and the icp sensor

What to do if your truck won’t start?

Either there is a massive leak, pump failure, IPR failure or simple ICP sensor failure. Most common are the connector right at the IPR. There are updates for it. Then a simple test for the ICP sensor is to simply unplug the very front valve cover pass through connector and try to start the engine.

Why does my MaxxForce diesel have low ICP?

The HPOP (high pressure oil pump) supplies the high pressure engine oil to the hydraulic operated injectors so if pressure drops the injection system will fail or run poorly. Our shop has had some experience with low ICP which can be mechanical due to a faulty o-ring on an injector or high pressure manifold.

When to replace a MaxxForce high pressure oil pump?

If the pump doesnt make the ICP described, put 12 volts & ground directly to the Injection Pressure Regulator (IPR) valve and retest. If it still will not make 3000/4000psi, or if the pressure is very erratic, the high-pressure oil pump will need to be replaced.

What to do if your MaxxForce DT has no oil?

Check your ICP sensor and harness and verify your actual ICP pressure When diagnosing a no or low ICP and no start complaint check that the high-pressure oil pump reservoir contains oil by removing the engine oil temperature (EOT) sensor. If no oil is present, check base engine oil pressure while cranking the engine.

When to shut down international MaxxForce DT No start?

Its not supposed to until you fire it up. Then the oil pressure is required to be past 25 to whatever value it likes within 8 seconds of a successful start. If not you need to shut down and check for problems.

What should fuel pressure be on international MaxxForce DT?

Fuel pump is electric on those and makes 95 psi, (computer only reads up to 75 psi though). ICP should be over 500 psi to start. What is your cranking rpm, voltage? It says it can show fuel pressure but doesn’t. I just got a cheap diagnostic tool.
