No other ideas? 

No codes. Not losing prime like when cups have gone before. 

Oh. And it does the same thing on either. 

Mack MP8. I had this issue one weekend, on a Saturday. She’d start then immediately shut off or die. I put new batteries in because they were week. I cleaned connections on cables inside battery box. Not sure if I did it by bumping something during removal or tear down but positive push button breaker was kicked. I reset it while finishing up battery replacement. I don’t know why but I always check it when I’m in there. It started right up. started and ran no problem. 
 

I got home Wednesday afternoon. Got up early Thursday morning. She started the starting then shutting down within seconds again. This is were she’s been for a few weeks. 
 

I had a fuel line seeping. Fixed that. 
I changed the fuel check valve or pressure relief valve on the head. 
 

still doing same thing. 
 

I tried checking ecm, and module wiring. I tried a test ecm. I am leaning toward electrical but I am at my whits end. any help would be appreciated. Thanks

Found the issue. Wires have been pinched behind a bolt when tightened. 

ThanksMackpro. I'll give it a shot. 

Can I check with a voltmeter? If so do you know procedure?

Coolant was drained. And I'm having a heck of a time getting air to workout. But looks like a wiring issue is likely the cause. 

I had to replace flywheel housing and just got back on the road. 7th injector was unplugged. 7th injector fuel line was removed and re-installed. Maybe plug needs some dielectric grease? Any suggestions?

Thanks. I reset it. It will start a regen. Then seems to almost always stop and throw the code again. However it has regend while sitting on its own a few times this week. 

Anyone know what

PP329 M128 01 04F 

is?
