Re: still will not run

A lot more detail is needed than this

Year, engine, codes, other symptoms etc..

Check the pressure at the fuel rail. If there's good pressure, next check for spark. If there is pressure and spark, then you need to ensure the injectors are working. For that you need a voltmeter or a test light. Hook the leads to the wiring harness and crank the car to see if power is getting to the injectors. You only need to test a couple of them, because even if only a few work, it will run...just like crap though. Remember... no start conditions are either no fuel or no spark.

could also be no air. Make sure there is nothing constricted in your intake and that your MAF is hooked up. I've actually seen a car that had the sreen blown to pieces and the intake melted that caused the car not to start

These guys have responded well to your question, my addition is rather rudamentary, but I've heard of it happening:

Does the tank have gas in it?

X2 on codes, another thing is #1 injector is bad , if so it will not start, I had that problem before. So further info needed.

Re: still will not run

One of those hoses/clamps on the fuel pump assembly may have come loose while you were fixing it. Others have had that problem, and I did too when I replaced a fuel pump on an Astro years ago. So you'd have the pump running, and a little pressure..... but not nearly enough to run the car.
