Hard Start first turn of key?

My '93 s10 blazer recently won't start with the first turn of the key usually. I can turn it for 2 seconds or 10 seconds and it wont start. When I flip it off and on to start it a second time it starts up fine. Occasionally It will eventually start but it seems to start up one cylinder at a time over a few seconds if that makes sense.

I'm going to check it's fuel pressure Monday. I was thinking maybe the fuel pump is struggling to build pressure and the time i take to flip the switch back and forth gives it enough time to prime? I have no drivability problems wide open though.

Any input is appreciated as always.

Your thinking is good.
Also fuel filter can be pluged up.
Check fuel filter first and then fuel pressure.
And always have fuel tank at 1/2 full or more to run test.
And also check for fast leak down.
