Been sitting too long
My truck has been down for a little over a year without a tranny. Finally got my HD4r100 and installed it. After buttoning everything back up, my truck won't start. I have two new batteries, and my volts are fine, but I can't build and ICP. I can barely reach 30! I filled the reservoir with fresh t6, but that didn't help at all. Where do I go from here?

Update: Iv filled the reservoir two more times now. The ICP just to about 430 each time, but dwindles down steadily as does the level of oil in the reservoir. Before I tried starting it, I put stabilizer in the fuel tank, took my fuel filter out, cycled a lot of fuel through the bowl till I fel confident it was getting good stuff, and them put a new filter in.

How long have you been trying this? If you keep getting a little more pressure each time, keep trying. Just remember to keep the batteries on a charger and let the starter cool down between attempts.
If you've hit a wall at 430 ICP, try applying 12 volts to the IPR so it will max out and see if that will get it started. Maybe you've got a stuck IPR.

the lpop will prime even if dry. when you build an engine there is no way to prefill it that i know of. it will just take 5-8 times to prime it.

It eventually started. I ended up putting in a CPS out of a different truck. Swapping relays 302 and 303. And replacing fuse 116. Even then it still cranked for quite a while and then finally fired off. It requires a really long crank each time, but each time gets a little shorter. I will replace the oil and fix a couple transmission line leaks and address some other issues when I come back from college next, and hopefully that will restore it to it's pre-hibernation state of performance. BTW, never try and route 6.0 tranny cooler lines on a 7.3.... it just doesn't work unless you are a really good pipe bender and can make some magical splices and adapters/reducers.

Thanks for the tip. Can you be more specific? Do you mean you bought the 1/2" hard cooler lines from a 6.0L 5R110W that connect all the way back to the transmission... and then tried to retrofit them into a 7.3L 4r100?
Or do you mean the 6.0L trans cooler fitting adapters and short lines that connect from a retrofitted 6.0L trans cooler to the existing 7.3L lines?
