Did you replace all of the manifold gaskets? Re-using old ones will cause vacuum leaks. How about the AFM, is it plugged in? I've forgotten to plug it back in a couple of times, and it either leads to a horrible idle, or no starting.

the old one or should i say newer one seemed pretty decent to me , everything is plugged back in the way it came and it just seems theres no fuel going thru the injectors because i ussually smell it coming out the exhaust when it cranks over with no spark

Crank it over, then pull a spark plug. If it's getting fuel, the plug will be wet with gas. You can also jump the yellow test connector by the passenger-side strut tower to pressurize the fuel system. If you can't hear fuel pumping through the rails, the fuel pump isn't running.

I have had this problem before. I am sure there is air in the fuel lines from your work. It should start after a few tries but if you jump the yellow test connector as rotaryrocket88 stated it should get gas to the injectors. Good luck.

This connector. Take a piece of wire and stick each end in the plug. This allows the fuel pump to run even when the engine is not. The key just has to be to 'ON'.

PLUG your AFM back in.(that is the big connector going to the Stcok Air box or whatever you are suing to Snorkel air to the engine!)
the car will just start and die if is not plugged in.
Deflood ths car,Check the plugs to see if you have Fuel( are they Wet?..excessively Wet?like shake them and gas falls off?FLOODED!).another thing you could have done is Reversed the fuel lines.Check the Lines and make sure they are on Correctly.

Please don't start new threads for an ongoing problem. Especially with a uninformative title called "Help!!!"

I merged your posts so that the history is preserved and people don't have to repeat themselves.

Good luck with your problem.

I have a similar problem - I jumpered the fuel cut switch which is supposed to make the pump run with the ignition switch on but the pump work. It will work with power straight from battery. Im thinking my problem is the circuit opening relay which is basically a fuel pump relay, have you checked yours for obvious damage?
