Does the primer get firm when your priming if not as stax has pointed out the transfer pumps can fail on a moments notice!But you should be able to get it to atleast light off for a second or so, also as stax mentioned pull the plugs on the ecu and check for coolant fairely common issue.

Make sure you got fuel in the tank s and noone has syphoned it off on you! you might give it a (small) sniff of ether( starting fluid) see if it will light off on that!It sounds like its getting fuel if your geting some smoke! Also have you loosened any fuel lines loosen at least two fuel lines at the head and prime till you get fuel at both then crank they can be real bears to get started sometimes.Once you got two cyls firing the rest will follow up the rear!

28 yoru getting what you pay for! at 32 your in the 400 hp range

You guys !(Most) of the time it is the timing advance solnoid block that causes this problem!On the odd occation the econovance can be hanging or have broken spring, there was a ts buliten about removing the screens in the inlet ports on this be sure you have done this also there is a bulliten for re routing the oil suply line at one point make sure it comes from the left side of the engine piston cooler gallery and the hose is in good condition!the hose may be falling apart inside! just some stuff to try!

If it has mack diffs It sounds like a power divider issue to me .Are you running un even tires between axles?

Guys the dogish nature of this engine is caused by the cam! If you go tweaking puters and the like you will just be wasting more fuel! the solution is to install the AC Cam In the AI engine The problem being it counterveens the emisson laws! all the smoke you see as you take off is unburned fuel that could have got you going but the rules had their hands tied!There are quite a few trucks in my area where we have no emisson tests and the ac cam makes the engine lift off as it should If you live in an area where you can get away with this do it! You'll never look back! But It aint cheap the job will likly cost u 3-4000 depending on where you go! but the up side is it will pay you back with the power and better fuel milage over time 1 mile to the gal is not uncommon.

84 superdog I sent ya a pm but thought others would like the info aswell! Heres the part #nos for the auss turbo and the turbo drain line for you guys that are into it! Barry should be able to hook you up with this stuff or any Mack dealer. Inlet has to be modded to use this, and the charge air pipes if your installing on an engine with a V pump! 681GC334A drain tube 631GC3142AM Turbo!

This statment is ture !The auss turbo spools real nice on these But if your turning up the fuel you need to be watching the pyro ! Which you should be anyway! we have done a few of these here on the island and every body thats done this is very happy with the results!The bonus is the dynatard works much better as well! And you need to remember to keep an eye on the air cleaner/s your moving lots of air!

This is not just an mp8 problem we have replaced 2 on the same mp10 and we have received one in the same condtion as the one we were replacing out of the box we refused to install it! They seem to be having issues with quality control on these hope they get this fixed soon!They make a mess of the engine compartment when they start leaking!

Yup no air no stop! Makes about as much sence as having an air starter but they are out there. But In some apllications where a remote stop is needed this would be an asset .

The truck driver asked to have a easy to push clutch pedal! They provided it for you!!! Oh you wanted it to disengage the clutch???You'll have to carry and extra cable for that!

Well I predicted A multi fit Cab 5 years in! DIDN"T HAPPEN ! I Didn't like THE BIG V either , We still have our own cab ??? So I guess Its still a Mack till the cab changes! And they quit offering genuine old school components. When that happens then the thing is truely dead . Swen and Ollie will have had their way at that point! Until then its a Mack.

I have Found over the years that engineers are never satisfide they are all ways seeking ways to reinvent the wheel even if there isn't a problem ,in this case to over complicate the simple ,a simple cable worked fine so lets add an air cyl to make it more unreliable.The 18 speed trans when behind a high hp engine has an " updated" tail shaft that shaft ALWAYS comes loose Didn't come loose before the update Why did we fix it! Only they know for sure ,OR Do they? Fact of life I guess!

Check your brake light switch on the back of the maxi button brake drl it is triggered by that!

Me neather! You want a job? WE do one of these a month at our shop you can come up my way and get some more practice if you Like!!! We have to plates you can do two at once!

good luck with it!

If you suspect the turbo take the inlet tube off and look at the wheel if it has been rubbing the housing or if you can physiclly make wheel the touch houseing the turbo is definatly suspect I have seen the adjusting nuts break if it has a jake brake but the noise would be continuous and your would have a poping sound in the intake!

judging by your coments Look for exhast leaks at manifold gaskets, There is also a vaque possiblity of a blown head gasket by your description!

Yup go easy pedal don't buy reman , Dont buy solo end of story! to far to back up when things go fubar!

PUT A NEW BALANCER on it ! you aleady have a used one the balancer is likly the issue! the blocks rarely have issues unless the engine has been cranked up! then they tend to crack near the starter and you will find the main bolts in the pan!

Hey Bro Chuck some cool water on the back of the fuel pump If the engine fires back up you will need to r and r the fuel pump and have it looked at at a reputable pump shop as the rack actuator is fubar!

Also check the plug behind the washer bottle on the rh fire wall 3/16 socket takes it part see if ya got any green conections there! Seen that do some werid stuff before!

Bro these trucks are American Made at least Thats more than can be said for KW at the moment! I hate the fact Volvo took Mack over too, but they have at least kept the build In the US.I was One Of the nay sayers when they took over But they seem to be building the brand I predicted a Volvo Cab by now We still have our own cab and The sales are on the increase! And They realy have there shit together on the emmisions front! Very few problems with the new units ! (aside from the wiring Harnesses)The Mdrive is starting to make inroads and IT IS as good as stated here Its a bit odd to drive but you get used to it!

If The fault light is not coming on when it shuts down its not somthing the puter knows or cares about! I have seen the the ECU fail when the cab temps get too warm! But re start was not possible till cool down! Check all the grounds and the plug to the fuel pump If you have any pins on the fuel pump plug the look to have been warm have the pins changed at the dealer !

Drain the coolant and remove and check the screen insid the rubber tube bottom of the oil cooler if its pluged replace it!
