short test run - minimum of parts installed after timing belt

[pdr1966sc]

I want to start/run VERY briefly before I completely close things up after timing belt and PCV work.

Yesterday I had it all buttoned up and no start - poor sounding - Exahaust cam was 180 off. Today I resolved that and have everything setup and just want to burp it before putting everything back together.

This evening I set the MAF in place, but no firing - I do not have the crank PULLEY on, nor the serpentine belt.

Ran out of time at that point.
I may have to pull plugs and see if there is excess fuel from yesterdays attempted start, and while there - do a compression test to verify the valves are in proper timing - but it does sound normal on the starter, just no firing.

I've started the engine momentarily without the accessory belt on, however I had the crank pulley installed. If you don't have the crank pulley on, what will keep the sprocket in place?

By cranking the engine over with the exhaust cam being 180 out you may have cooked the goose. Instead of the valve opening on the up stroke it was opening on the down stroke. So if the valve normally starts to open just before the BOTTOM of the preceding stroke, then at 180 out it would have started opening just before the TOP of the preceding stroke - a possible recipe for disaster. I don't know how much overlap there is in these engines. You should probably run a compression check to see if all is well. You may have dodged a bullet.

When you first put the belt on (with the cam out of time) did you pull the plugs and crank the engine by hand through a few revolutions to feel for any piston/valve interference?

Does the engine use a crank sensor and doesn't the crank pulley have to be on for that to work? If not, don't all the air ducts have to be in place to start it?

The only test run to do is with hand cranking the engine over and confirming the timing marks line up. I don't see why you would run the engine here - no value at all.
