Forget reading that thread , I think the best part about it was the wheelied golf kart Pic . I do appreciate that coming for a guy who race 2 wheels

Ok I checked the timing of the pump today . looks to be in timing to me . I could not see marks threw hole but I got it on compression stroke lined marks up on balancer and the dial pin was at 4 o clock with one bolt straight down at bottom . I put all new injectors in the engine And bleed the air out the system a couple times . looks like I am getting fuel to the injectors . It has took a while because I do not want to burn up starter. The truck acts like it wants to hit but nothing so far. Sounds like I am getting closer . I am tired of starting on it so we are going to pull start it for a little bit see if we can get it to hit off. The injection pump is from diesel Performance in Tenn. I don't know if you guys have had any dealings with them . I have a different IP If I can not get it to hit after we pull start it for a Mile or so them I am going to change the IP . I will check back with you guys later today and let you know if she fires off .

If you read the hall of shame, many of the posts are about diesel performance in Memphis. Their "rebuilds" have proven to be a new gasket set to seal it up, but not a new head and rotor. I am betting you found your problem when you found who rebuilt this pump.

We are pulling the Pump right now to try that before we pull the truck up the road . I have a pump that I know ran about 6 months ago so I am pretty sure it is fine . We get it bleed up and try that . If it don't fire off them I am going to pull it up the road . I will be back later with what I find out . Thanks CP for the quick reply . I thought I had saw something about them god I hope this is it .

By the Way all of you guys have been great with the help .

I think you have found the problem, low compression. "Wanting to start" is another sign that everything is right, it just doesn't have enough compression to fire off.

I worked on a John Deere small tractor with the same problem. Tore it down, and it had been overheated, all the rings were stuck and coked up with carbon and burnt oil. I had to replace one piston, honed the cylinders, cleaned the grooves up in the other pistons, new rings, and it fired right up.

Engine rebuilders make mistakes too, so don't depend on it being right down inside just because it's a "rebuilt" engine. Until you can get the compression up where it's supposed to be, I don't think it's going to run. I have done a lot of compression tests(gas engines) and when a engine is healthy, it only requires about 3 revs for the needle to jump up to it's peak value.

Changed injection pump . checked timing , Checked glow plugs which are working . Engine still will not fire over . Going to pull start it Thursday nite when I get back home if not going to pull it down to see if rings are stuck or some other issue .

Back to the compression and leak down before you take off unessesary stuff .I tend to do that some times but the guys around here keep me on the right track ..

Low compression is your enemy. No amount of timing or IP changes will make it any different. Did this engine ever have a turbo on it, as far as you know? That could be the reason for lowered compression readings, and since it seems to have low mileage, that would be the reason for even readings on each cylinder. I have an old engine in a truck that would not fire, and most of the cylinders are under 200 psi. Pull the engine and take it apart. That is the only way you will figure out what is wrong. Maybe double head gaskets, maybe flat cam, maybe broken rings, maybe bent rods, maybe cut pistons, maybe bad karma. Don't waste any more time f**king with timing.

A leak down test is helpful to determine where problems lie, but it is usually used on a running engine to pinpoint the issue. You can try it on yours, it will not cost much in energy spent, but may not be very specific as to finding the culprit.

ITS ALIVE ITS ALIVE . Ok Guys here is one for you to ponder . I got home Thursday and me and a buddy decided we would pull it up the road . After about a quarter mile I started to see smoke and she fired off . You could not see the truck in front of you from the smoke out the truck . I pulled it in a parking lot and let it idle for about 20 minutes and drove it back to house. The truck idled great but flooded when I gave it a lot of fuel . So I decided to give the new injection pump one more try . Changed the injection pump back over . Long story short the engine runs great starts with less than a couple seconds of cranking . Great oil pressure no heating issues. So I have a 4,000 miles engine to go into my old wore out roll back . I will post pics when I am done . Cause I am going to change fenders and doors while I am at it and lay some nice metal flake paint on it . Thanks for everyones help . I bought a 90 dually today with 6.9/7.3 I don't know yet I have not took chance to look under the hood More to come .

Great news! BTW, these diesel engines do not flood. Sounds like something was malfunctioning in old IP. Glad you got her running

 

[Spun4Fun]

Congrat man .. It's a good feeling when it comes alive

 

[IDIoit]

so *** was the issue????

 

[franklin2]

The engine only had 4000 miles supposedly, but who knows how long it had been sitting. I think the rings were stuck, and pulling it down the road unstuck them/generated enough heat to where it ran but poorly. Running it more loosened the rings even further. I think the ip problem was a different problem all together, since the faulty ip didn't seem to prevent it from starting, just revving.

I wonder what the compression would show now.
