Injection Pump Front Seal in the Midwest

Hey guys,

I've been getting some stalls on really cold starts with my 4M40. I did some research and it looks like the most common culprit is the front injection pump seal. I should also note that I am am also getting a leak of some type... It's a thin fluid, and I can't tell if it's fuel or antifreeze, so not sure if it's related. It only started occurring in the cold.

What are some things I can try before I get the seal replaced? Some people are saying to drain the fuel filter? Maybe I should just replace it entirely, since I don't really know the last time it was replaced... Anything else?

Does anyone know any diesel mechanics in Saskatchewan/Alberta/Mantibob that could do the pump seal replacement for me? Just looking for someone with experience.

I’m in the same boat
I have order the parts to do a IP seal, they are already in my possession. I have a shop that I trust and is willing to do it.
But we haven’t booked it in yet!
The Mitsubishi mechanically book says the job is 3 hrs!!
I’m not sure how that is possible very place I’ve been, says 7-9 hrs.
But that’s usually because they send it out to another shop that just does pumps I guess!
My mechanic is in Calgary

Do you have any documentation on the job I could give to my diesel mechanic?

Thanks.

Hey Jerry
I’m using the guys at Heritage Auto Pro
Their mechanic did his apprenticeship in Japan and worked on many Mitsubishi’s,
And JDM imports.
I trust them to make it right.

We haven’t done it yet! I’m not in dire need right now. I’ll wait for the summer as I’m planning other upgrades and repairs.
They said it slows down after Christmas till Feb
