Default Car Wont Start After cam swap. Need Help

Hey guys my car sat for 2 or 3 months while it was getting a cam swap. Well the cam is all done and the mail order tune is in. Its a 306 cam and I started her last night without the tune and she ran great til I ran my hand over the maf (I started it without the Cold air intake on) and then a loud back fire and wouldnt start back up.

Foudn out the starter was split, got me a new starter, and she fired up then died right away.

She'll start now, but its kinda scratchy when tis turnin over, I figured it was the starter, then as soon as it starts it immediately dies. If you give it a bunch of gas you can delay it a little.

Any ideas? Or things I should start with first?

Do you think it could possibly be bad gas?

unplug the MAF then try to start it and see if it runs, did something get into the MAF?

So A buddy came over and I tried to start it and it fired up and I kept it runnign for a few seconds and he freaked out cause a big flame shot out of the intake track. I was running open maf without the K&N on.

You think it could be the maf, Im sure tis fucked now?
Maybe I have the rockers to tight and its keeping an intake valve open?
But then why would it have ran with the stock tune?

ALso I unplugged the maf and tried and its no better. It still dies but I just let it fire then didnt give it any gas so it died right away. Do I need to try and keep it runnign with the maf unplugged and see if ti clears up?

Also dont forget there was a bad backfire on the stock tune when I ran my hand over the maf
