Back on the road, near Cumberland Maryland

M1088 slowly died while going uphill and slowed to a stop and lost power.

Possibly alternator dead dead but batteries are full and it will turn over but no start.

Call LL if anyone can help with assistance even advice

Fold the cab. Drivers side look at the engine computer it’s on the block. To the right of the computer is a power filter box. They go bad all the time and the engine computer looses power. Measure voltage in and out if that box. There is a breaker in the dash for it. Sometimes it trips the breaker also.

Look at fuel filter... Try primer to see if it pumps with some tension? If tension but still no run maybe fuel filter?

If it will it run short while after priming then you may have an air leak .

I have pulled and dumped the primary filter. The pump is getting firm but has never tried to start

hmm...... guess you go to what Will/suprman suggest then.

Will.. that electric filter box can be by passed right?

drain a cup of fuel from bottom of tank to see if you have algae or water in the tank. Hate to ask..... but you sure you put diesel in it at last fuel stop and not gas. ?

Honestly that’s why I drained the filters to check if the place sold me the wrong fuel.

It is diesel. My soaked clothes are a testament to it

 

[Cgray]

So got the fuel drained just as a precaution and added five gallons of know good diesel. Drained filters and lines and reprimed.

Nothing.

Dead truck.

Looks like Ike we are going to that CAT dealer via tow truck

Is your oil level at the mark? Dunno if it's a c7 or 26. A c7 will die if the oil level is low. especially on a hill
Do you have a test light to check for power to the fsv?

I always jumped the starter with a screwdriver while I pump the prinee for cranking. Bleeding either one shouldn't be that bad

It is a C7.

Checked the oil and it was good to go and at the full mark.

At CAT dealer now and they don’t seem too excited to even look at it.

I may just be screwed.

Most cat dealers are good with them. I would start by seeing if they can communicate with the engine computer and go from there.

Trying to convince them to hook it up today and try to communicate with it. The service manager wanted to push me off until next week sometime.

Waiting on the owner to make a decision, seems like a good group of guys and I am hoping for the best.

 

[simp5782]

Well if it needs a ride back to WI just let me know.

Simp,

Already had you in mind.

Know anyone who has a truck to tow a 43’ gooseneck back there as well?

Ok. CAT computer on.

3lbs fuel pressure
220 lbs oil pressure. (Needs over 800 to start)

Looks like Heui pump gear has failed.

Anyone have ave one laying around they want to sell?

Cat said that? 220 means pump is still turning! What about IAPCV?

 

[coachgeo]

In past someone mentioned they had an injector not seated fully and was causing issues. Might save you ton of mula if it is that.
