Cummins, Houston

99 295, problem.  Cummins problem.  FYI. 

Check engine light came on outside San Antonio, soon went to powered down , made it back to N Houston,  Mumbled , to self put out a call  who said the same,,  tried a few, my thought bad fuel.
Called a couple of recommended guys busy "probably bad fuel" mobile guys are busy. I am 84. Got free help. Killed the codes, started w. New filters. Light back on, still showing strange codes on P.O.s $400. Gizmo killed them, back on.  Called Cummins got a call back week later,  for a appointment Monday 3/7/22.  Limped it in, with tow.

A CUMMINS,
Trouble started, pleasant guy, welcomed me, pretty soon a guy showed up with a computer, "now w will have the truth" unplugged the gizmo.  Did not plug any thing in,  fidled with his  computer, (no plug for the computer to the coach attached  to his computer??) went back to the engine  fidled a little more disappeared.  (1)did not want to embarrass him, 99 was way before wireless communication,,  on such ..

After a while went in, ask pleasant guy ? Waiting for some one to get back from lunch..  went to waiting room another owner, discussion, his thought was that either of the 2 .. I Talked to were probably "sacking groceries" 2 weeks ago. 

Some point, 2 guys apparently appeared got in as I got out (Lounge) to look they were driving off.  Around 1:30..  around 3 the pleasant fellow appeared, advised the other folk what was happening.  Looked at us,??  we are cking for parts, u definitely need a valve before the injectors & a electric thing, after that maybe a ECM.  (We all know that name?). No idea.

Since I have called,  I.guess, talking to the original computer "operator" ??  gained info might be a pump, no idea, lift or injector?.  New thought I think his part,  needs a ECM.  Can't find parts in the system, reaching out to the  Cummins dealers??

With that, would appreciate any thoughts (Texas heavy truck,) has been brought to my attn. but at the time he had  big commitments , nice guy to call back but thought fuel filters we're the Issues.. he is #1 on my list, if Cummins can't provide answers & I can get it out of there. 
 My thought they are the equivalent of the old days TV tube thumpers, keep replacing stuff until the light goes out?

I am in a mess, wife wants to go to  La for 4 travel group.

This is my last, best, & cheapest Mo Ho.  My last experience  CUMMINS was a blown engine , all total $40,000. A outstanding experience, Cummins Houston got a little of that  $$ fixing what Cummins  Spartinberg SC.  got most.  (Mostly cover after mkt warranty)..

THOUGHT, a listing , dated of " savvy" mechanics". List would be nice..

Houston, Cummins,,  as I can understand can no longer support these older engines.  My thought..

Hi Bill,

This is Walter. We had lunch together a while back. I too, have a 99 coach and could bring over my Silverleaf VMSpec laptop and compatible cables Tuesday if that would help and try to capture any codes the ECM (electronic control module) the ECM is generating. We could also take a look at the fuel filter, air filter gauge and anything else folks on the forum suggest taking a look at. I am not a mechanic but think with some help from the forums fellows we could rule out/narrow down what might be the cause of your problem. I'm willing if you are.

Quick edit update: searched fforum and as I understand from reading others comments: checking oil & coolant sensor connections, sensors and fluid levels were noted as resolving some derating problems. Pierce, I don't know how to check discharge pressure but maybe Cummins does...

Fellas, any thoughts on what to check? or a forum discussion on Troubleshooting this sort of issue? If Bill wants I can bring my tools, vom and vmspec and whatever I have that folks might think I should try and bring. Bill, just let me know if you would like another set of eyes & hands.

After filters, check the discharge pressure from the lift pump under load. A failing pump can cause codes, problems and damage. Cummins lift pumps do fail. A bad injector or injector wiring can damage the ECU.

Houston? We have a problem. Sure wish you the best of luck on this.
EMT living in Missouri. Recently purchased 1987 Gran Villa 36 Ft. long,460 Ford engine with 40,000 miles on it, new tranny has 3000 miles on it, coach has 75000 miles on it, new 5000 watt genny new fridge, new tires. Am both excited and scared out of my wits at the size of this beast. Love it but need time to become accustomed to it's size.  I'm sure it will take time to experience all the secrets this RV has to offer. Any and all advice gratefully accepted.

Would do what Wbates says and in the meantime find a shop that works on the older engines,they are out there,if you don't trust
or like the Cummins shop why even go there,they are not the only shop around.Forget about the Foretravel group for now and get the coach running.

Bill,

Do you know off the top of your head what the voltage was on the dash or electronic reader you have. On that ECM of your coach, if you have low voltage you will have all sorts of troubles. Trying to sort out the simple stuff first like alternator, isolator, or batteries.

Walter, & others.thanks, got to get it fixed or our of Cummins is my 1st problem going to try to find someone beyond the "grocery sackers" tomorrow, learn a exact problem. Find if it is together, whatever, through with BSers  I hope.
Will be glad to accept the truth from them. Easiest, (cheapest?) at this point for them to fixit.

Filters, cut the pulled racor, 10 micron, cut in to it no crude,no water.  So don't think that was a problem...

I can't believe in Houston there is not virtually every part new or rebuilt for these engines ,  Cummins is married to Cummins so that is where they source parts, period?

Again thanks to all for the good thought's.    Bill

I did not think up the term Grocery sackers, he apparently had big problems, full timers in a new 45'?.

Bill,
The 1999'~2003-ish Cummins ISC's used the CAPS fuel injection pump. This is the first generation electronic version of the C8.3 and the design used what is more properly termed a priming pump than a lift pump, since it only operates for 30 seconds or so when you turn the ignition on. From there, it is all suction from the gear pump portion of the injection pump assy. In other words, your CAPS pump is sucking fuel from a long ways. My theory of the case is that internal seals wear over time, and when filters get clogged, may get damaged by running dry because the seals are lubricated by the diesel. Anyway, when the gear pump gets weak and can't keep its prime under load, the ECM will throw a check engine or a stop engine light with several possible codes. I believe that the root cause is fuel starvation. Assuming you have already replaced the the OEM fuel lines and aren't sucking air on the suction side of the fuel circuit, Cummins will likely want to replace some very expensive parts of the CAPS assembly. Spoiler alert, there aren't any cheap parts in the CAPS assembly. I went another way... I may someday have to replace the CAPS pump as who knows how much damage may have been done to the CAPS pump through multiple instances of fuel starvation witnessed by the stop engine light, but I am quite sure that I have postponed or possibly eliminated that eventuality.
My fix for what I am convinced is a fuel starvation problem, after first doing my best to make sure that there weren't any air leaks on the suction side of the fuel circuit (keep in mind, Foretravel replaced the fuel lines before any of my issues started), was to install a FASS UP95 electric lift pump that operates full time so that the CAPS pump does not lose its prime. I also installed an Autometer fuel pressure gage with a remote sender so I can monitor the feed of the CAPS pump. Under 100% load on a steep grade, the fuel pressure never goes below about 12.5 PSI, so I know there is no fuel starvation. Before my fix, I struggled with intermittent stop engine light for over two years. The first iteration of the problem happened after a bad load of diesel. Several rounds of fuel filter changes later the problem subsided, but subsequent filter clogging events caused the stop engine light to rear its ugly head again, even after having the fuel polished by Keith of MOT and changing the primary fuel filter system to a Davco 382, a new fuel cooler, etc.
Perhaps your issue is something completely different, but I suspect the root cause is the same.
Good luck!
Don
Since installing the FASS heavy duty lift pump, which feeds the CAPS pump diesel with a low pressure high volume flow (15~17psi), I haven't had a single incident

With that we are within the Cummins sight ,  with  little hope of ever emerging...
  Bottom line, the root cause failed" surge suppressor ".    7300. B bucks.

Think this is the last we need of Cummins??

fix the idea of a continues "lift pump". Appeals.
,  Will post any other fiasco, which  it has been a fiasco , from not longer after we drove in.

Surge suppressor?
Please elaborate......

Are you saying $7,300 (7.3 coach bucks? to fix?

Without seeing Bill's post I figure Cummins found the suppressor inside the CAPS pump had failed and killed (or think that it had killed) the electronic side of the pump (the accumulator pump). This was an upgrade of the CAPS pump that was on the mechanical engine when Cummins went to the ISC  computer controlled (around '98). Seems like in or around "03 or so Cummins went to the HPCR system. Rather that fixing Bill's pump Cummins will always replace the complete pump.

There are kits or you can resource the parts used to convert to a mechanical engine for both the 8.3 and M11. Used parts would be a fraction of the price. Bosch P pumps last forever.  If staying with the electronic engine, I would add an electric pump and sensor with remote instrument panel gauge for fuel pressure. Facet makes good pumps. The cylindrical pumps are reliable and used on many PowerTech generators. I've had a square type fail and leak. Round ones have a filter that can be cleaned or changed. Work on biodiesel or gasoline, etc. Gold-Flo – Facet-Purolator  For 155 gpm, higher pressure but a little more $, check this one out. Robot or human?

I'm not knowledgeable on the recommended pressure for Cummins diesels so check before ordering.
