92 740 turbo died again....

It has a new AMM, new crank pos, sensor..only a few K minles on tha part.

Just playing with the kickdown adjustment, somehow I went from a good , smooth-running engine to a dead engine! THe engine had been running perfectly for months, except for tranny not going into O/D. When I was making repeated starts last week and adjusting the kickdown cable, after a few normal start/runs, then when I started it, I noticed it running rough.Also, it was trying to die, wouldn't idle so I had to give it lots of gas to keep it going. It ran rough like this for a couple or three short runs, after this when I cranked it, it fires like all cyilinders are firing good, yet it never "catches" and runs. I was only working around the area of the kickdown cable/throttle body. I thought maybe I bent a vacuum line and induced a leak.....Guess it could be that. WHat is it suposed to be when cranking? I have had the timing jump way out on this car before....however the alignment mark on cam pulley is still lilned up. I had to repair that not long ago, the pin had corroded away, so I made new pin out of a broken drill bit.

I took the damper bolt out and looked at the crank notch and key....the key is undamaged, still in the notch. So it doesn't look like the timing has slipped.

Since it just sits there firing but never starting when cranked, I need to know what vac is supposed to be when cranking...seems like a good chance that its a vac leak since it seems to be firing good and timing doesn't seeem to have changed.
