dont jump into replacing EUP's.. remove the chrome heat shields, and see if the EUP wires are chaffed, and rubbing against the engine block.. the insulation does wear, and break off or rub off.. if the wires are exposed, you can use a brush-on wiring protector to cover the worn wire insulation. did you check the condition of the wires at the flywheel sensor? RPM/TDC sensor.. it is also very common that the wires on the engine side of the harness to be weak and even attached by only a few strands of wire. I have also found the pin in the plugs to be broken and barely touching.. since yours is a dump truck, there is a lot of sh!t coming off the left steer tire, and getting on to this wire harness.. Keep in touch...... jojo

no throttle pedal codes?? boost sensor issue??

Thats what I thought.. How long have you owned this truck, and what other trucks have you driven, that you are comparing this one too?? This truck should pull very well, but it aint no racecar... are you downshifting more than normal?? jojo

Yeah,,, I just had to pick a little bit, to stir up a laugh... truth is... I'm clueless.. I do know that you will make a smart choice.. I wish you luck on this one... for what it's worth.. I own a Moffet Mounty, that I bought from a customer... they were going to scrap it.. I have had it for 11 years. I used it today... I knew the history, so to me the purchase was easy.. jojo

are you hearing a boost leak, excessive black smoke?? The combo you have should be a damn good truck. I assume a triaxle dump truck.. what do you haul? I also guess its an E-Tech.. '99 or newer? jojo

I feel like 9000 is worn out for a 'Ho',,,, jojo

when was the last time you put new fuel filters on it??

I have only been to about a dozen truck show's... But No Mack's at the show would be like vendors not selling Hot Dog's and sausage sandwhich's,.. Oh yeah funnel cakes and fried twinkies too,,,, jojo

Bob, I would be surprised if No Mack's are allowed.. jojo

Too funny Bob,,, for years I have made a joke about how to get everything for free,, it was to be a black lesbian in a wheelchair, with 2 children.. Oh well, I guess my 'White A$$' will just have to keep paying their rent, and 'Obama phone' bill,,, jojo

we have a lot of people in charge of departments, that have agenda's, rather than 'a job to do'.. and if you call them out' on these issues, the first thing they say is you are a racist, and that is white supremacy speech.. Then everyone gets scared and lets them (Demonrats) do what they want to do..

The engine harness is one piece, One thing you could try, is to swap the #6 EUP with another easy one to reach, and see if the code follows the EUP.. you can do this carefully with out damaging the orings, just make sure the chamfer is clean and smooth before installing the EUP.. then when you torque the bolts, be careful. new bolts torque to 60lbft, but you may want to back it down 10lbft.. when you go back new, you will have o-rings and get new bolts at that time.. jojo

Thats one of my questions, TJC

ok... first check the 2 wires going to the EUP for chaffing... are you having low power issues? the Mack code is 8-6.. so what tool are you reading it with? Do you know that when the lightning bolt is on, you can flash the codes with the cruise control buttons? jojo

Lets see how we can tie this one to our KING.. The prisons here in central N.C. are putting Narcan, in the vending machines for drug overdoses... Really???? I already have a headache and 20 question's.. But I literaly have tremendous back pain and my left knee is about to fold over... i cant get affordable care for either issue.. So I just keep working.. I am not looking for a free ride,, just want to get fixed so I can finish the last 15+ years at work.. without having to buy a wheel chair... just sayin'... where the hell is the concern for those of us who are in the same boat as I am?? jojo

No Dog's allowed???? so no Mack's??

the fuel system is easy... you can get what you need here when you post questions.. your engine is an ASET-I,, basically an E-Tech with a few tweeks.. as far as schematics's... yes, good to have, but if you have a V-MacIII book,,, and a skill set for elec diag.. you can fix all of it... V-MACIII book #8-211....(there are new issues) E-TECH #Engine 5-106... jojo

I have never done it to a Mack.. On my svc. truck, 2002 Isuzu NPR.. I removed the egr valve and cut a piece of sheet metal, punched bolt holes, put it in between.. then plugged the vac. line.. catch my drift??? jojo

You are a 'TRIP' BOB.... Luv U Man... jojo

I dont know of 'One' book that covers it all.. So.... I assume you want engine/ tranny/ driveline/ rears/ elec. schematics? What else? I have many REAL books for your truck... I hope you have a manual tranny, which would be a 300 series.. I have all of them too.. What I dont have is extra E-Tech/ ASET books.... jojo

It's good of you to show respect for your truck.. It is also good to hear that one of these Volvo's with Mack badges is serving you well.. I am quite sure the Manual tranny has a lot to do with your satisfaction with the truck.. I get upset because Mack is an American Name that goes along with the industrial growth of our Great Country, since 1903... It is every bit of a 'War Hero' as is the men and women that put it ALL on the line for us.. Volvo just lined the Mack up on the wall, and yelled, FIRE!! Keep up the good work Rubber Duck.. God bless you... jojo

I assume you are watching the engine temp gauge...? jojo

turn the A/C off and see if it still does it... Keep in touch, and welcome aboard!!! jojo

R.E.D. I hear ya... I agree with you.. as long as PAI and others keep making good quality parts, and guys with the knowledge to fix them still exist, you should be good for a while.. I have a lot to learn, but I do hope to be a Mack Doctor some day.. jojo
