Crank journals #2+#5 are the oil feed to the heads.. the cam bearings have an oil gallery that basically goes half way around the bearing, making them easy to warp when installing. Did the cam go in smoothly?

🤔

WOW!!! what a beautiful machine... I wish it was mine... Jojo

Thanks "V"

So China reports that they had their best economy in the world during 2020.. Go figure..... So what will they give to the world this year to stay ahead..... Another virus, How about Nuke's... Biden will let it happen to us as he hides in the Bunker..

👍✌️

Holy Crap!!!! I would love to drive that and kick some "snow bank ASS!!" I came from Maine, and I have been many places where that truck would "Get it done!!!" Jojo

on the fire wall.. open the hood, look at the left side, theres a 4'x6' black box... i think its in the 3rd row from the left, 3or 4 slots down from the top.. 25amp

You know......? This another reason that I like this site created by BMT.... I read posts and it jog's my memory, and then I can share what I learned... Jojo

Thanks "V" youre right..... Now I remember chasing one of these issues many years ago... I took a new battery off the shelf and grounded it to the truck, then ran a jumper to the E.E.C.U. fuse, #40 and powered the E.E.C.U. with the "isolated" battery, and the truck fired up.... damn good call "V" Jojo

So.. They want to make D.C. a state.... OK.... Then force California to be it's own country, and get that state off of our tax bill... Then they (CA) can take on all the southern border jumpers...

That truck is "Tough"!.. does the CL in the background have an E-9?

ok.. Good signs... have you checked the E.E.C.U. J-1/J-2 plugs for coolant wicking as stated in a previous post? is fuse 40 loose or dirty? its in the fuse box on the fire wall next to the steering column.. I'm trying to think of other things to check. do you have chaffed wires to the E.U.P.'s? are they secure on the E.U.P.'s? one repair I have made several times, is the harness coming out of the power distribution on the firewall rubbing on anything and shorting out the wires? jojo

Is the engine worn out? low compression due to age, please tell me you are not using ether to fire it up..

OK. now it sounds like a ground issue...pull the cluster, fix the ground to the left.... open cab fuse panel, fix the ground iside there, clean the ground breaker contacts on the firewall next to the stater relay, clean the ground behind the left steer tire and the other end of it on the engine block.. and just for kicks... make a ground wire that grounds the E.E.C.M. to the engine.. bolt it to one of the mount bolts betweeen the E.E.C.M.. and the mount stud.. they are not conductive to the block....

Well Ben.... I'm not at dealerships anymore, so.... I can't help you with that part.....there are some here that do work at Dealerships.. they will be a better source... good luck on getting the answers you need.... keep trying... jojo

these values are for both timing sensors

Interesting..... Any codes?? have you checked the Eng. Position sensor next to the overboard breather filter, and the RPM TDC sensor in the flywheel housing, at 10 O'Clock , (left side). you can Ohm them to see if they are open, you can also unplug one and try to crank the engine (after its been running and warmed up) if it cranks on the one thats plugged in, then switch off, and plug the first one back in then unplug the second one and try to crank it. if it doesnt start, the sensor that is plugged in may be bad.... I know "V" has the specs for the Eng. pos. sensor depth to the cam. I have taken the teardrop shim out and "Bingo' it cranks right up.. I will look for the Ohms. I think it's 900-1500 Ohms resistance... jojo

So when you remove the fuel filters, the fuel is low in the filter? Have you looked at the fuel lines from the tank to see if fuel is bleeding through them? I assume you checked the lines from the filter pads to the lift pump? There should be 3 lines and a #12 line that comes from the tank.. jojo

It runs, I have to get the hyd. brakes to work before I drive it. The tires are a few years old but have Zero miles on them. I'm also going to re-do the wiring, thanks Terry... Jojo

V-Mac I and II are very basic, and most diagnostics is done with your, eyes, ears, nose, and hands... If your P.C. has "Mack Software" you can use it. Does P.T.T. still link you to "Mack Software"? Assuming you are at a "Mack" Dealership...

I think Ben needs to tell us what model he's working on....

I think youre right... I thought later that it was '94 for V-MacII,, I coudlnt remember the plug thing, but now I remember hearing the plug on the firewall was a way to tell... I'm forhetting some things because I dont work on too many early 90's trucks as much.. heck,, iv'e been working on more mid 80's trucks lately, 3 superliners in the last 6 months...:) Jojo

I would like to see a picture of you're KB8... I just bought this one and am about to get it road ready... I'm chomping at the bit, Jojo
