Question about Cars & Trucks
With the information given it is kind of hard to make a correct diagnosis, but I believe I would look at the correct firing order. If it ran ok before the tune-up and runs worst now it sounds as if you might have gotten a few of the wires in the wrong place.
You will want to start out by removing your number one spark plug and either hook up a remote start switch or have someone help you turn the engine over while you put a finger over the spark plug hole in the head. Just bump the key over little by little until you feel air being pushed out of the plug hole and stop when the engine's timing mark lines up with top dead center. If you pop your distributor cap the rotor will be pointing at your number one plug position of the cap. Start there with the number one plug wire and work your way around clock wise in the firing order of 1,8,4,3,6,5,7,2 If having the wires in the wrong order is your problem, this should get you sorted out.

I assume the fuel pump fuse is good?
The only time voltage will be sent to the fuel pump will be the first 2 to 3 seconds if the starter is not engaged. You will want to crank the engine over and check for voltage on the load side of the relay, circuit #30 at the relay.
Let me know after you check.

If vehicle was left outside or in an unheated garage, there is a strong possibility that condensation has contaminated your fuel. Easiest way to check is to remove fuel filter and pour contents into a glass jar. If you see two different layers of liquid in the jar, the bottom part is water. Replace with new filter and drop the tank. Remove sending unit. pour contents into a large container and clean out inside with clean dry rags. Remember, fuel is dangerous to work with and fumes travel pretty far on the ground. So, no open flames electrical stuff, cigarettes etc for a good perimeter around work area. Generally, you can re-use top 3/4 of fuel you removed by syphon. Don't use remainder in your vehicle. Part can be used for lawnmower etc as long as you only take the part above the water line.

i do believe it will not start with out it if you can hook up a scan tool to it crank the engine and look at rpms while cranking should read about two hundred forty rpms thats what fires the injectors the cam sensor tells the computer what cylinder is ready to fire next also scanner will set the cam timming.
