T444e no start in 70 degree weather

[Qya1991]

Any ideas on why my 1998 T444e won't start in 70 degree weather? Pops once and that's it. And white smoke. Could this be the glow plug relay?

Could be.

Have you tried using silicone spray or WD40 in the intake as a starting aid if you need to get it to run? BTW, do not use starting fluid on an engine with glow plugs.

No but thanks for the idea. I'm trying to find the problem causing the issue.

3 things to check


Getting fuel or filters etc clogged, pump dead or...air in system

You need air, lots of fresh air so check airfilter

You need heat for ignition so are you sure you have any.

Those are the only 3 things needed for combustion.

We have essentially the same engine and essentially the same problem. Here's easy places to START.

1. Batteries. Make sure they are fully charged.

2. Oil level. Even slightly low oil can cause starting problems.

3. The air filter.

4. The fuel filter.

5. Check fuses. There are a few specific ones that are known for starting problems, but fuse layout is probably different from the 7.3 to the t444e (though I don't know) so I'd just run through them all with a multimeter checking for continuity. It only takes a minute.

We've got through all that. The next things we'll be looking at include:

-testing to see if the glow plugs are getting electricity
-testing individual glow plugs to see if they are still working
-replacing the starter
-replacing the CPS (I've been told to order this and not go with anything that "matches" from a chain store
-doing a compression test on individual cylinders

Good luck to you! I'll let you know if we have any luck.

Worn injectors can also cause hard or no start at 70 degrees. If you are getting white smoke then you are getting fuel. If you do not have some sort of scan tool to monitor icp pressure and ipr duty cycle it is going to be hard to diagnose.

its a Nexiq USBlink2 abd the soiftware is free from Nsvistar for the basic version.. ServiceMaxx J1708,

its $400 / year to go to the NavKal which is more in depth but for what we do not really needed.. you can change things like VIN ID's and alter Transmission parameters (for 1000,2000,3000).. {sorry no horseopower upgrades.. those are kept under tight wraps}..

Power upgrades? Just turn up the screw and slap on a couple more turbos!
