Engine start up problem

I am trying to start my engine for the 1st time since rebuild. It cranks but won't fire and appears like it's not getting fuel. It's a 302 Ford, mechanical fuel pump to Edelbrock 4 bbl. I am pretty sure I set he initial timing right and wired the engine correctly. Can anyone give me some advice here as to what are the potential causes.

Engine start up

Thanks for the tip - that helped. Now it is clearly getting fuel and almost starting but not quite. It backfires and spits fuel out of the top of the carburetor. It flamed out the top of the carb once. I am a little spooked right now. Obviously, this is the first time I have ever fired an engine from scratch. Sorry for the dumb questions - just don't want to smoke my new engine, or worse. Any body have any suggestions.

double check firing order.
you are close,but timing is off. hook up timing light so you can set timing and RPM as soon as it fires. get the rpm over 2000 as quickly as possible. set timing around 30 .

302 firing order is different than the HO302/351 firing order.
Correct order is determined by the camshaft.

1, 5, 4, 2, 6, 3, 7, 8 counter clockwise for 302. Is this right?

You probably are 180 degrees out. You verify by getting #1 piston to Top Dead Center with both valves closed, that will be #1 on the compression stroke. Good luck

Hydraulic lifters? Was the engine primed? If its a flat tappet cam, careful with all the cranking as you can wipe off the cam breakin lube. You may also be 180 off on distributor. ???

engine start up

Thanks, I think I am off 180 degrees. I did prime the engine but it is flat tappet and I am concerned about wearing out the cam with all the cranking. Should I pull the valve covers off to make sure both valves are closed on #1? I am running out of tries before things start to wear down. I assume I shouldn't be having flames shoot out of the carb. That's pretty freaky - scared the crap out of me.

I was off on the timing but have now corrected it. I am sure #1 is at TDC and my balancer is set at 0, rotor pointing to #1 on the cap. Engine is cranking and wants to fire but the backfire is still there and the carb is flaming almost immediately. This is freaking me out.

Engine start problem

Thanks to everyone who answered and helped out I was able to get my engine fired up. Turns out the problem was the cam I put in required the 351W firing order, not the stock 302 order. Soon as I switched the wires it fired right up. What a tremendous feeling. Thanks again.
