You can ohm the injectors and glow plugs from the harnesses. That will get you started anyway. Injectors should be at our close to 3.2 each, glow plugs 1ohm each. Glow plugs are outer two pins on each wiring plug, injectors are the ones beside them. The center is a common ground.

what part of the desert are you in? If you are near by I'd be happy to help.

And you do the ohm (resistance) testing with the key off.

Just a update on the hard starting stroker, my hpop pressure was low, i filled it up and started it and it started bad the first time but as it was idling it kind of reved up and went back to idle and smoothed out very nicely, then i shut it down and let it sit for a bit and cranked it up again and it fired up like it should, one thing i am wondering though is when you fill up the hpop if you over flow it does it need to be pumped out? i was once told that the over flowed oil will run back into the oil pan and it would be fine, is that correct? and one more thing, im going to change the oil in the hpop with a oil change and im wondering how much oil does the hpop hold?

You don't need to change the hpop oil. You're still not getting all the old oil out that way. It circulates all the time so no real need to.

You can't really overfill the hpop. Once the resevoir is full, its just gonna run out and make a mess. It holds around a quart, give or take a little.

Oh ok hahah, im hoping its not leaking somewhere, it was only a 1/4 qt low was all but it made all the difference on the way it runs, if it was leaking somewhere wouldn't it run empty or would it find a spot and stay there? and if there is a chance it is leaking where is the most common places they leak at?

After running that truck a bit yesterday i had checked the hpop oil again today and it was a 1/4 qt low again, there isn't any way that it can mix into the radiator fluid is there? or is it something that comes from the oil cooler? that truck has some issues with leaks im trying to seal up hahah, i know the oil cooler is leaking for sure.

Oil cooler can allow coolant to leak into oil or vice-versa. But remember, there is no "HPOP oil" per se. What you see in the reservoir is part of the lube oil, and gets circulated every time you run the engine.

Is there a place that maybe it could leak out some? i know on my 7.3 mine is to the top at the bolt i pulled to view it, i filled it up 6 months ago and its been there ever since and i was told it would go back down but it hasn't but on my wifes 7.3 it goes back down there for some reason and when it is as low as it gets it runs bad, it wont hardly drive without almost dieing if its not warmed up to opp temp and it idles very rough, rough enough that it gets the engine rocking back in forth but when i top that off it fires rite up without any trouble at all, i do know its got some leaks needing fixed i just need to find the place it all comes from, the oil cooler is one of those places for sure, its time to park that truck and hunt them all down and seal it up to see if that keeps it full, is there any common places that the hpop would leak if at all?
