Again thanks for the info, once i pulled the pin cover off again to find the pump pin I went up and felt the #1 valves, they were not loose. Immediately knew what i did wrong.
Thats what I get for being in a hurry.

Looks like you thanked the wrong dude... .

Stock pistons, stock cam,16 degree ppump timing, 60 valve springs, 4K gsk’s, lift pump spring upgrade, -8 fuel lines with sump, dual feed, 24v oil pump, 13in ceramic clutch.

Once together I bled fuel, got fuel leaking from each injector, tightened down and attempted starting. No go. Won’t even fire off and try to start. Pretty sure starter is on its way out after trying for so long. Works currently but will stick in “starting” position at times, after repeated start attempts.

So I checked injection timing, thinking it may have slipped. Nope, still where I set it. Checked cam timing, “0” and “00” are where they are suppose to be. I had pulled ppump to reset to pin time (couldn’t see timing flange in pump. Putting back together at stock timing now)

I’m out of ideas. Other than maybe the crankshaft might be out 180 from the cam. Is that possible? I had cyl 1 at tdc when I put the bottom together and assumed that putting the cam mark with the crank mark would be good enough. But is it possible that it could be off and cause the no start?


Cliffs.
Rebuilt short block
New fuel system
No start
Ppump timing good
Cam/crank mark good
Fuel shut off valve is up when starting

Good rule of thumb is to crank for 15-20 seconds then wait a min or two.
You'll burn that starter up faster than you think.
