Won't Start Symptoms
Your car may not start for a number of reasons. The following list outlines the most common circumstances and tells you what action you can take to try to remedy each situation:
The car cranks over but won't start. Check the fuel supply to your engine. If that's okay, check whether the electrical spark is getting to your spark plugs.
The car makes a clicking noise but won't start. This sound usually means a dead battery. If not, check the wiring to and from the starter for a loose connection.
The engine starts but dies. If your car has a carburetor, check your carburetor adjustment and your choke to see whether the choke is first closing and then opening. If you have fuel injection, you'll need professional help.
The car is silent when you turn the key in the ignition. Check the battery terminal cable connections. If they look very corroded, force the point of a screwdriver (with an insulated or wooden handle) between the connector and the terminal post and twist it to lodge it firmly. Then try to start the engine. If it starts, you need to clean or replace your cables.
If this doesn't work either, then it's time to take it to a mechanic.

What is the fuel pressure at the rail?
Can you measure ac voltage at the injectors?

Kelly, could be a few issues, security lock out, crank sensor, fuel pump fuse/relay, faulty new pump,faulty ignition switch, etc. Attached links may help you diagnose the crank no start issue you are having.
Check the attached links,video,instruction and guides, Good luck

Check all fuses first, then with an assistant, check for spark with a spark tester. if there is spark at 2 plugs, check for fuel pressure at the fuel rail with a gauge. Engines need three things to run, fuel, spark, and compression. If there is spark and fuel, do a compression test, if the timing belt jumped/broke, you won't have any
If a starter is able to crank the engine but it won't start you usually have either an electrical or fuel problem. It's also remotely possibly that it's compression.If an engine has proper fuel, spark and compression, it will start when you crank it. So your challange is to find out which part isn't working right. Start with fuel. Spray a little starting fluid into the air intake while someone tries to start the engine. If it starts briefly when you're spraying starting fluid, you probably have a fuel delivery problem. That could be injectors, fuel pump, fuel filter, relay, fuse... who knows what until you check into it.If it doesn't start with starting fluid, check the spark. Pull a plug wire and attach it to a spare sparkplug and set the plug on a solid metal part of the engine. Have a helper crank the engine while you watch the plug. If you have a good spark, it might just be out of timing.In any case, you'll need to start isolating the problem. Find out which part isn't working then you'll know what to replace/repair.
You say t pump is coming on, but do you fuel coming up to the fuel injector rail? You can check for fuel by pushing down the valve located at the left front side of fuel rail. It looks like a tire air fill stem. Be very careful as fuel is under 40 psi pressure and can spray all over the place. do this with engine OFF and have a rag to cover the valve. Just press with tip of screwdriver and be sure valve is covered. If a little gas come out,you know you have fuel. If not gas then check fuel delivery system i.e pump, filter, lines or pickup tube.
If there is fuel in the rail, then there is most likely a problem with the control module (computer). Check for fault codes with an OBD II reader. You can usually rent one at your local part store. You can look up fault codes to find out where the problem might lie.
