the fuse on left side pulls apart on last batch of M2 I had, that you checked already. make sure its got pwr thru it?

 

some m2s have the issue of the pdm (fuse box) on the driver side fender, the main harness going from under it vibrates to much and can crack a fuse (wont be able to tell unless you pull the fuse and wiggle the terminals and look thru it), also can cause the wire terminals will come loose under the fuse floor.

 

Check the PDM connections on the DS inner fender for corrosion. Especially the Green one .
Also check the powetrain PDM down lower on the firewall for corrosion of connections and relays.
More info would be needed, year, etc for better 500 foot diagnosis.

someone rigged this and burnt fuse box , guess i'll start here , thanks guys , please if ya have anymore info post it

 

The Blue 10Ga wire in the Green plug is for the blower motor

 

From the looks of the powertrain relay center, dirt and crap all over, I would be checking the connections there also and getting anew cover for it.

 

i replaced all fuses and with key on i can hear / feel the repays clicking , i do have a cover . will look there and try what you said

 

You can google the engine code along with brand and size of motor, may give you an idea where to look.

The burnt wire in the green connector is common problem, need to fix wiring there and check blower motor amp draw
to keep from happening again

 

dang i thought i was on to something , thanks tho , got parts coming to fix that , need to know why it wont run , just cranks , that "NO ENG" code i believe is the problem , my problem is im not a truck mechanic but have sum knowledge

i work for the city and have no books on this truck , pretty dumb right , lol , these old guys just patch stuff around here

 

What engine does it have?

 

cummins

 

The "NO ENG" code means that the engine ecm is not communicating on the data link. Most likely it is not getting either battery or ignition power due to a problem in that powertrain PDM with the missing cover. PM me your email and I can send you a schematic to help you. As others have stated check the fuses for power in and out not just visually because they have been known to crack internally.

 

just replaced connector and fuse box , same issue

 

PM SENT , thanks for the help

 

Did you check fuses and wiring that goes to the engine ECM in batt box?

 

yes looks like 3-4 buss style , any more info would be great , got a electrical sech. bullet member sent me , bout ready to call a service tech but damit i hate giving up ! :-damnit:-damnit:-damnit

 

This might be a long shot but we have Freightliner chassis' on our Thomas school busses at work. We had one that died on the road and it was a rotted splice in the engine harness that runs under the oil pan.

 

will check monday , thanks

 

ecm was at fault , thanks guys for your call and help ! :tonqe:
