88 gta need help after diy engine rebuild

I am today cranking it
It has fuel pressure
and after I can smell gas
I checked my spark plug wiring firing order 2 times
it's not starting
I think I'm 180 off I heard a pop 2 times
I'm gonna go crank it again and listen and maybe try quick start
just a bit

if it's still not starting it has to be 180 off
what's the easy way to do it

Ty for the help advice

it has fuel pressure

it just backfires 2 times so I stopped
it has to be the 180 out
I was super sure it was on
I had the valve cover off and watched 1 it looked like if was tdc

this happens everytime I take it apart
It was running perfectly just smoking oil minority
I put new rings and new rod bearings and put new gaskets
the problem is I can't check the compression in all 8 unless I take the headers off
I just got new reflex gaskets

I can't only snake the tester in past the 2 driverside 2 passengers side front cylinders

Re: 88 gta need help after diy engine rebuild

Probably the wrong #1 TDC; the #1 TDC where the #1 exh valve is closing and the int is opening (which is also #6 firing), instead of the #1 TDC where it fires.

Eeeeeeeeeezzzzzzy enough; line up the timing marks more or less, lift the dist acoupla inches, turn the crank exactly 1 turn, drop the dist back in. Piece o cake.

Re: 88 gta need help after diy engine rebuild

I just took 4 hours and redid the 180 out dist timing
and it started first crank
instantly
zero gas pedal
and I shut it off
I forgot to hookup my wideband o2 so it had a leak I heard it
it nerds coolant and oil top up
I'm gonna let it run tomm with me watching for leaks
thank God
I wish there was a way i could get past the 180 out forever
does anyone know good ideas so if only does this everytime
