When I start my vehicle it doesn't start right away until I push really hard on the gas... is that a sign of a starter going out?

If starter doesn't spin everytime. Clean battery terminals and a connection. Check connection at starter. Try putting into neutral to start. If starter still doesn't turn car over everytime. Probably starter solenoid. If starter spins every time and doesn't start check temperature sensor. My car once started only when sitting for a couple of hours. Because sensor was saying it was really cold and it would flood it. Had to push gas peddle to floor and hold it there until started. If that is the case change temperature sensor. If car is after mid 90s take and get it scanned.

Try to crank it without throttle to get the gas out. Pause, try to start.

Sounds like your injectors have no power. Check fuses, and connections on the back of injectors. Then follow the wires back and make sure they are connected properly. If you have a power tester, see if you have power to the injectors as you are turning it over.. And stop using spray on it. That is very hard on any vehicle including diesels. Very hard on them

Can\'t really help you with the no start problem without more information, but would advise you to stop using starting fluid right away. Starting fluid is hard on Diesel engines but they are made for much higher compression so will usually survive intermittent use of starting fluid. Gas engines just plain can\'t handle the much higher than normal compression that starting fluid produces which will destroy valves, piston rings, connecting rods, starters, ring gears on the transmission and head gaskets in short order. If you don\'t want to have to completely rebuild your gas engine don\'t use starting fluid on it ever!

check plug for heater switch. if your ignition switch is just past on it can that to.

probably the alternator, when you replaced the battery it had a full charge and once the vehicle used all that charge up and it wasn't charging it could no longer start the car anymore. If your battery light is on in the car it is a fairly certain sign that the alternator is not charging. Generally an AVR test is the best way to check the alternator, but if you can jump start the vehicle, connect a voltmeter to the battery it should be around 14 volts when the vehicle is running and around 12 volts when the vehicle is not running. If it is not at 14 volts when it is running, it is not charging.

replace the starter. Being a manual transmission you should be able to pop the clutch to get it going till you replace the starter. If you don't know how to pop the clutch follow these steps. That way you can still drive the car. When need to.

1. Get inside the vehicle and depress the clutch to shift the car into "Neutral." Insert the key into the ignition and turn it to the "On" position. This is the place the key would be after a normal turn of the ignition switch for starting. Instead, with a clutch pop, the ignition will already need to be on so that when the engine is turned over, the key is in the On position.
   
2. 
   Move the car in position to be pushed from behind or sent down a slope for the starting procedure. Check to see that the brakes will work when pressed and how hard the steering wheel will need to be turned before the vehicle is started. Power steering and brakes will make both systems work poorly until the vehicle is started.
   
3. 3 Sitting inside the driver's seat with the clutch depressed, put the shifter into first gear. Keep your foot depressed onto the clutch and the brake pedal without depressing the brake pedal. Roll down the window and signal to your helper to push. As the car rolls, you will steer toward any slope that will assist the helper in getting the car down the street. Allow the momentum of the vehicle to increase to constant motion.
   
4. 4 Release the clutch quickly and be prepared to throttle the gas pedal as the engine is turned over by the motion of the vehicle. When in gear, the engine will be forced to crank and the ignition will send a spark for a start. The quicker the vehicle is going before the clutch is released will determine how many times the engine will turn over. More cranks equal more opportunities to ignite the gas and air for combustion and the engine to start without a battery or starter
   

Has the service engine soon light come on ?

This could be caused by a lot of different things, don't replace parts until you know for sure what the problem is otherwise you will just be throwing your money away,

If the service engine soon light IS on then go to auto zone and have them get the codes, on your year you may have to have them turn the ignition key on and off five times, then count the number of flashes of the service engine soon light and then look up the codes in a haynes repair manual for your specific vehicle.

This is not the fuel pump. It sounds like the computer is not setting the proper fuel mixture.

I just had this exact problem. Wouldn't start or took 15 trys to start, but then ran smoothly. Sometimes a little rough starting on dry days, but pretty much hard starting after rain. I was thinking water in my tank/bad gas, but shooting some starter fluid in my intake didn't give me the initial blast at start up... that certainly indicated that it was electrical...
...but the next day the vehicle stalled in the middle lane of a three lane street, wouldn't restart. After pushing it to the curb, I got to the point where I was checking the wire from the coil to the distributor cap. Two thirds of the wire lifted right out. This wire was in 2 pieces! Amazing that it had been running at all, with this one wire burned down to a whisper, before it broke completely. There were signs of heat/elec damage to the wire also at a point an inch away on this wire.
Replacing the wires is absolutely the first thing to try. It's cheap and easy to do, and it should be done (or the wires inspected/tested) routinely anyway. The coil-to-distributor coil gets more engine heat and more use than any of the indiv spark plug wires and hence wears much faster.
I am betting this wire is much more likely your problem than a coil failure. Good Luck!
