Moose junior ip acting up

I'm going to call Mel tomorrow but I am having some problems with my new pump. It idles great but when I drive I can only build 7 lbs of boost and then the truck just falls on its face. It won't rev up past like 2500 rpms when I drive. I thought it was my waste gate so I put a valve in and it still having the same problem.

Ummmm.... hows your lift pump??

 

[FastestIdIinthe707]

I have an electric one on my frame. It provides more fuel than the factory mechanical one.

 

[sjwelds]

sounds to me like you still have an incoming fuel supply issue....

 

[FastestIdIinthe707]

I'll check it tomorrow. The truck did sit for a while. But the diesel now days is terrible

put a gauge on the filter head before you call Mel, without this we are doing nothing more than guessing.

 

[FastestIdIinthe707]

Alright I'll see what it reads.

Filter(s)? Lift pump? Just had a plugged up filter the other day. Was fine to 2000 RPM then was slow and a bit stumbly at times above that. Fresh filter with 50/50 diesel kleen/ATF and back to normal.

bet you 20 bucks its either fuel pressure, or timing.

 

[FastestIdIinthe707]

Might be timing. But would being off one tooth allow it to still run? I still need to get it timed perfectly

yes it would,,been there..get it timed...

Our engines can and will run 180 degrees out of time!! That means if someone did not know about the "Y" and Dot marks on the cam gear they might have mistimed the gears. This has been found on a few engines in the past. Being 1 or 2 teeth out of gear time can change timing a lot too.. Bring the damper timing line up to the short fat probe location at the timing tab at the damper. Then remove the front cover and look at the injection pump gear. See if the drive pin is in the 4 o clock position.

my engine ran at -9*
i was 2 teeth off.

Are you sure that the throttle is going wide open, have someone push the in cab foot to the floor, then look if the IP is wide open.

 

[FastestIdIinthe707]

Thanks. I'll check it. Maybe I jumped tooth when I put the pump on
