We did the spider and fuel lines kit in his '94 S 10 4.3. Had to pull lower intake to get heat on the bolt that holds the fuel lines to intake. Had to pull distributor to remove intake. got it all buttoned up and it fired right up., shut it down until the next day, it was late. Next day I drove it up road and back, 1/4 mile total. Check gauge light came on showing low oil pressure, I turned it around ASAP and it died just before the driveway, had to drift in. Engine locked, won't turn over with starter or my hand. Removed plugs to check for hydro lock, cylinders dry. I pulled dizzy again to see it it would turn over. The dizzy was loose and spun easily. I watched my son tighten it, but didn't check that he got the hold down clamp over the bottom of the shaft. Nothing was holding the dizzy down! Spinning it a little in either direction doesn't change timing on these, computer controls timing. Would not having the clamp on dizzy allow it to raise up under acceleration just enough to disengage from the oil pump shaft? That's the only thing I an figure locked up this once decent engine!
