Wont start even if i push her,toyota tercel has no spark

So your telling me that this car is a stick and you can't pop the clutch to start it ? Correct?
I'm gonna give you a list of thing to check, good luck.

a)Do you have crank no start? (see entire write up)
b)No crank no start?, ( battery, battery cables, ignition switch,,starter relay)
c)No dash lights, no crank? (battery, battery cables ignition switch)
If you have symptom A then the affected items are , ignition switch, battery, battery cables, starter, starter relay ,coil, coil pack, ignition module ,Distributor cap ,rotor, (if applicable) spark plugs and wires.
The best thing to do is to first make sure your timing belt didn't break. As long as the engine cranks you can do this. Give the battery a 3 min charge . Then have a helper crank the vehicle while you observe the rotation of all the pulley's and belts. They must rotate together. If the vehicle has a distributor remove the cap ground the coil wire and watch the rotor as the engine is cranked. it should spin. If this is a-ok your worse nightmare is over.
Now we have eliminated the timing belt as being a cause. We now have to charged the battery again for three min and load test it( this is best done by a repair shop a load tester is expensive .If the battery if more than 5yrs old you may want to replace it.
If battery does not pass load test replace it.
Whatever you decide the rest of the items can NOT be checked out without a fully charged battery.
Check ignition switch and starter relay for B+ going to them and leaving them. Check starter circuit. Make sure B+ is making it to starter ( use a digital voltmeter). If B+ (12 volts) is making it to the starter and it doesn't crank then the starter is defective. Do a starter current draw test to verify this or remove the starter and have it bench tested.
If starter cranks now your into coil testing .
Pull a spark plug hook it up to a spark tester and ground it, now crank the engine if you get spark coil is ok and in all likelihood so is module.
If you don't get spark test for spark at the coil wire.
If you get spark here and don't get it at the spark plug wire problem is at distributor cap , rotor or spark plug wire. If plugs look bad use a fresh plug to do testing and naturally replace them.
If all of the above are a-ok.
Next is fuel checks.
Easiest fuel check is to put key into ignition cylinder and turn to on position. Lister for pump to buzz or hum. if it doesn't then check fuel pump relay for B+ going to it and leaving it and going to the pump. If B+ making it to pump and it doesn't turn on the pump is your problem. If B+ not making it to pump either the relay or the ignition switch is defective.
Naturally if the pump is defective have a repair shop do the repair . Its dangerous and a real pain.
Good Luck
IN YOUR CASE I BELIEVE YOU NEED A NEW BATTERY UNLESS THIS ONE IS FAIRLY NEW.

I have a 1999 dodge durango,i replaced new spark plugs and new wires but the car won't start?

Do you have crank no start? (see entire write up)
b)No crank no start?, ( battery, battery cables, neutral safety switch ignition switch,,starter relay)
c)No dash lights, no crank? (battery, battery cables, ignition switch)
If you have symptom A then the affected items are , ignition switch, battery, battery cables, starter, starter relay ,coil, coil pack, ignition module ,Distributor cap ,rotor, (if applicable) spark plugs and wires.

Whatever you decide the rest of the items can NOT be checked out without a fully charged battery.
Check ignition switch and starter relay for B+ going to them and leaving them. Check starter circuit.Do not forget neutral safety switch its on your brake pedal and once depressed it closes the circuit to the relay so B+ can travel to it . Make sure B+ is making it to starter ( use a digital voltmeter). If B+ (12 volts) is making it to the starter and it doesn't crank then the starter is defective. Do a starter current draw test to verify this or remove the starter and have it bench tested.
If starter cranks now your into coil testing .
Pull a spark plug hook it up to a spark tester and ground it, now crank the engine if you get spark coil is ok and in all likelihood so is module.
If you don't get spark test for spark at the coil wire.
If you get spark here and don't get it at the spark plug wire problem is at distributor cap , rotor or spark plug wire. IN YOUR CASE YOU HAVE NEW PLUGS AND WIRES SO IT WILL BE EASIER TO CHECK FOR SPARK.If all of the above are a-ok.
Next is fuel checks.
Easiest fuel check is to put key into ignition cylinder and turn to on position. Lister for pump to buzz or hum. if it doesn't then check fuel pump relay for B+ going to it and leaving it and going to the pump. If B+ making it to pump and it doesn't turn on the pump is your problem. If B+ not making it to pump either the relay or the ignition switch is defective.
Naturally if the pump is defective have a repair shop do the repair .THERE ARE FUEL PRESSURE AND VOLUME TESTS DONE TO VERIFY IF PUMP IS DEFECTIVE OR NOT. IF WITH THE TESTING PROCEDURES I'VE GIVEN YOUYOU CAN NOT DETERMINE WHETHER THE PUMP IS DEFECTIVE HAVE A REPAIR SHOP DO FURTHER TESTING ON THE PUMP. THESE TESTS ARE A LITTLE DANGEROUS and a real pain.
Good Luck

I have a 2002 Sierra Truck. The battery is good.

Do you have crank no start?
Do you have no crank no dash lights nothing?

Items to check out Battery and battery cables (Load test battery and make sure cables are clean and tight especially the B+ cable off the starter).
Listen to the cranking speed of the starter. Does it sound normal or slow? Depending on what you hear you may want to do a starter current draw test or have a shop do it for you.
If all of the above are a-ok then move onto fuel and ignition checks. AT THIS POINT YOU SHOULD HAVE CRANK NO START.
When you put the key into the ignition and turn it to on position do you hear the fuel pump buzz?
No buzzing sound ... you could have either a bad fuel
pump or relay. Either way the vehicle is going to a shop for further diagnosis and repair.

Unscrew a spark plug attach it to its wire and ground its electrode . Crank engine and look for spark.
No spark! Now check plug wires and coil. How? Use shop manual for correct testing procedure .
If no spark is found coming from the coil then check B+ coming from battery to coil and ignition module.
Lastly not likely , ignition switch should not be left out of the equation. Your gonna need the shop manual for that test procedure. Good luck

My f-150 it will not turn over battery is good but not geting voltaeg to starter help

Use a test light and check at the starter solenoid and see if the ignition start wire gets hot when the key is turned to start. If it does check to see if current then goes thru the solenoid to the starter. If it does check to see if current gets to the starter, if it gets to the starter the starter is bad. If no current to the starter or out of solenoid the solenoid is bad. If current does not get to the solenoid when switch is turned, check and see if the current goes thru the neutral safety switch (Clutch switch if not automatic). If the current doesn't go thru the switch replace the switch. If you are not getting current to the switch in the first place check the ignition switch. If the current doesn't come from the ignition switch to the safety switch replace the ignition switch.
