HELP PLEASE..... Can't get it to start

Just recently removed my intake manifold and cleaned it out and replaced the manifold gasket cleaned whole throttle body and eveyrthing and im excited to see how it acts when i get everythign back together and boom when i do ..... nothing... turns over and over and over and nothing so i read a couple posts on it and maybe i have the ditributor off by one tooth maybe more maybe the full 180* so i flip it around and try the only other spot where it fits and when i kick it up it backfires on me white smoke out of the intake, but it doesn't start. So i read a lil more play wiht the timing.... disconnect the EST and play a lil more now i finally got it to stop kicking back but its back to turning over and over. I maybe low on gas before i started i had maybe 1 gallon left.. so i add about a half gallon and still nothing. my car was running pretty well before hand but i looked at the intake and the throttle body and decided they needed cleaning as well as the water neck needed replacing. But now i'm regretting even oipening the hood... this is my only mode of transportation so any help would be greatly and i mean GREATLY appreciated. Thanks in advance....

I would definetely think it's the timing. I know you have played with it, but try playing with it some more. Check all your connections as well, including everything from spark plug wires to the distributor connections.

Work with the timing until you get it right. Another member on this board messed with their distributor and got it 60 degrees advanced when I came to help him. Funny part was it started but was very very rough and pinged like crazy. Instead of pulling out the distributor again, we simply backed off the wires by 1 spot counter-clockwise. Timing was dead on 6 degrees when we fired it back up. We were lucky that day that it was an easy fix, you may have to play with the distributor to get it back on to a workable timing.

I changed the timing moved the cables a position around and it still is puffing back at me.... the reson it stopped puffing is that i had the distributor disconnected from the coil by accident so i didn't try it how i had it... i'm at work right now but i will be trying to play with the timing as soon as i get home.... until then... back to riding the bus AHHHHHHHHHHHHH!!!!!

thanks for your help i ended up pushing the coil wires 1 to the left (clockwise) and the engine tried to start and calmed down a lil bit with the back firing.... i pulled the distributor and flipped it 180 pushed the coil wires back to were they were and then moved all my wires 1 to the right (counter-clockwise) and twisted the distributor counter clockwise and the engine start... ****ty but it started... it was baout 19* advanced with the EST disconencted... so i corrected it and brought it back to dead 0. flipped the engine off and reconnected the EST... only problem is i put the wrong damn gasket on the water neck... so the coolant got all over the engine... but for soem reason despite being in california.... in 90* weather the engine didn't even come close to overheating... thanks again for all your help.
