2005 DT466e Crank no Start

Wish you luck.

I got the new injector wire harness installed, and it seems we are making progress in the right direction. It is attempting to fire, and I have smoke coming out of the tailpipe, but the ICP seems low.

With a bit of starter fluid to revs up normal sounding but then it doesn't stay running.

I am wondering if It is the IPR valve restricting oil flow causing to low ICP or if there is something off on the timing not allowing the RPMs to climb high enough for the HPOP.

Does anyone have any ideas?

DO NOT USE STARTING FLUID !!!
Your bus has a grid heater and you do not want the starting fluid to ignite that soon!

SILICONE spray is better or the old school way of gas on a rag works too...but you get gas smells on your hands now!

I might be mistaken, probably am, but if you disconnect the IPR connector the bus should run ...not for driving though, for testing....

Also, Did you check IPR voltage?
You CANNOT accurately check for power and ground in the IPR circuit with the thing unplugged - the circuit NEVER operates that way (unplugged).

You need to check voltage TO the IPR valve with the connector plugged in. There must be battery voltage with the key "On". If it is more than 1/2 volt lower than battery voltage, you have a wiring problem.

My Bus is a Florida bus and doesn't have any cold-weather add-ons. So I don't have any kind of grid heater on the air intake.

I think the IPR is a valve, and if the valve is shot, removing power won't necessarily leave it in an open state...

I am in the process of getting access to a copy of J1939, hopefully by tomorrow to be able to do some KOEO test... I will keep you posted.

That's interesting, my bus is a 2005 AMTRAN RE, Broward County bus and it DOES have a grid heater!
Grid heater is not the same as block heater...That my bus does not have and well as cabin heaters...but it's got great A/C!!!

That's funny because my bus came from Valusia County, had 2 ACs, and 2 floor heaters + cab area heat and defrost.

For the longest time, I thought it had grid heaters because I got the "Wait to start" light, but I was live on TikTok one day working on my engine, and someone pointed out that I don't have the wire leads that would go to the grid heater on the air intake. So even though it says wait to start, it isn't actually doing anything... No wonder my bus doesn't like cold starts

Want to try something interesting??

The IPR is nothing but a needle valve operated by a coil. I was wondering if they just get gunked up and start failing.
If you grab a very thin needle you can lightly push down on that needle in the throat of the IPR, clean it out with brake cleaner followed by some WD40.
Re-install and see the results, if any...

DUDE, my bus HATES cold starts! i got a fresh in-frame, 5k miles on the clock, and it takes at least 6-8 seconds of cranking in this Texas heat!
When it drops to 60 degrees it will crank for at least 15 seconds before she will fire up! And I have grid heaters...ARGH!!!!

I'm willing to give it a shot. Looks like rain is moving in here on the west coast, so that might have to wait until tomorrow.

This might be a dumb question... when I take out the IPR valve, is oil going to come running out of the port?

No, maybe a dribble... FYI, I carry a spare IPR and ICP in my bus. They are used but were tested to be good on my engine. i put new ones in and keep the spares for just in case....

also, if you do need an IPr I would caution against using an aftermarket one. I did, 2 of them, both times bus started but tons of errors when viewing in Servicemaxx so I went with OEM. Almost $500 bucks!

So I got a copy of Servicemaxx, but my engine isn't under the pop-up for select engine... I tried J1939 and J1708.

J1939, if I click the 2007 engine, I start to see some data, but not all of it.
J1708 I don't get anything, and no pop-up to select the engine.

The yellow data light comes on with J1939, but does not come on when I try to use J1708

Any ideas?

out of curiosity, go to the help tab and see if it tells you what version of the software your using...
Like I said, mine works!

I finally got it to show more engines, and it shows multiple components, but when I try to do anything else I can't get any data or info... When I click on the DLCII I6 (2004-2006) it doesn't show these components. If I click MaxxForce 5 I get some data, but it still won't give me all the details or let me run KOEO tests...

DLCII I6 (2004-2006)

this is what I select, and it works for me...

 

[SeekingDiscovery]

I'm leaning towards it might be time to pull the ECM and IDM and take them into the International Dealer next week to have them do bench testing on it and make sure they are working properly... ugh

 

[ewo1]

I was looking at your pics, on the servicemaxx screen, where is says "J1939 MODULE CONNECTION" there is a check box next to it. uncheck it and see if it works.

Your original issue was a running problem under load which turned into a problem with the wiring due to attempted repair. You got the engine to run, be it briefly, leading me to believe it is a fueling issue, possibly the filter(s). Can you pull any codes manually without the scan tool?

I finally had success getting it to run! After putting the new injector harness on, I started to see more signs of life. After posting a video online,e most folks said it was air in the system from replacing the check valve in the fuel system and that it needed to be bled.

After a lot of smoke and a clunky start, she fired up, and I let her run for about an hour and get up to operating temp. The real test will be trying to start in the morning and then go for a test drive locally.

Fuel system check valve replacement? Did you mention that in this topic??

That was one of the things discovered while trying to diagnose the no-start. Realized there was a missing o-ring on the check valve in the fuel filter housing. Got that replaced to make sure it wasn't losing prime.

Even though I got it started yesterday, this morning it doesn't want to start again. Lots of white smoke while trying to crank. The next recommendation I was given is a Cam sensor replacement which I will attempt in an hour or two.
