also could there be an issuse with the IP like the throttle is just wide open? because today it seemed like the engine had the throttle wide open when the lever wasnt even touched? idk if that makes sense?
also can i just run the ATF like 100% threw the system while running? or do i have to mix it in with diesel fuel?

Yeah, the IP might be wonky.
Running solely on ATF is fine. I sometimes keep a gallon in the trunk as backup fuel

so i went ahead and put in the other IP i had and with the cold start switch on i got it to start up and idle with it off it turns off i guess i should get a gauge and get the ip all in time. anyway real happy to hear it idle.

Okay so i picked up this dial gauge kit from ebay it looks all good but when i put it all together and go to put the dial gauge on it it doesn't fit in all the way without it already applying pressure onto the gauge making the needle spin.
what do i need to cut down to make this work how it should or is it working how it should?
here some pics of what I'm working with.
and also the rod that goes inside i know it had some threads on the end of it does that screw into somthing inside the Injector Pump?
im just trying to fully understand how its works.

thats how its supposed to work, u push the gauge in and it tensions up, then u rotate the engine until the gauge stops moving, zero the gauge and then move it back to tdc and the amount of travel at tdc is your timing measurement, i forget which ways you rotate the engine becaus ei haven't done it for a while.

take the nut off the bottom of the dial indicator...then screw the extension in. Hopefully you get it from there.

For example:
The thumbscrew on the side allows you to pre-load the gauge and turn it to face you after the adapter is threaded into the IP.

okay so i got the gauge all in and i put a pre load of 2mm on the gauge atleast thats what i thought i did its the smaller guage on the face anyway so i set it in at 2mm. and then i rotated the engine opposite way it normally turns. The gauge spins and then it stops so then i rotate the face of the gauge so that it reads 0. Then i cranked it back to the TDC but what puzzles me is the gauge doesnt move at all? what am i doing wrong? i can supply pictures if that helps as well
i was following this DIY i know the bentley says 2.5mm pre load then rotated then do a 1mm pre load and then rotate back to TDC but this thread says just leave it at 2mm?

With the engine @ TDC, I would preload a minimum of 2.5mm. 3mm is also fine. (The preload ensures the gauge tip follows the plunger all the way back in its travel.)
Then turn the engine backward until the gauge stops moving. No need to preload any more, just adjust the face of the gauge to zero and turn the engine forward to TDC again.
The gauge should show some positive movement. Loosen the pump bolts just enough to turn the pump (if you haven't already), and turn the pump until the gauge reads the specified value.
If the gauge does not move when you turn the engine forward, or turn the IP, something is not normal.

okay so heres where im at.
first id like to show everyone that i have the IP lined up with the Mark on the bracket and the sproket is lined up there as well.
and the fly wheel is TDC
okay so anyway i put on the adapter and then i set the gauge to about 2.5-3mm pre load ( I'm assuming that's what the little gauge is for ) with the smaller dial )
and then i turned the crank in the opposite direction as the engine normally turns and it changed the gauge to look like this
and so i turned the face of it to make it read " 0 "
and then rotated the engine back to the TDC and nothing changed the gauge didnt even move. So i dont know what the deal is? Also i noticed once i took the gauge out there was alittle fuel on it and kind of leaking from the adapter is this normal?

OK, not normal, lol. The gauge should go lower when you turn the engine backwards.
So, it could mean a few things:
- The crank is not at #1 TDC
- The IP pulley or key is whack
- The IP internals are whack (usually 180)
I would verify
#1 is at TDC (#1 cyl is closest to the IP)
IP pulley key is in place
IP pulley is rotated where the locking pin can be inserted (if there are two Pin holes in the pulley, verify the keyway is pointing toward the head.
Repeat gauge procedure.

okay ill check it all and then try again. Also what is the IP pulley key?
