    Did you clean the terminals? chances are that taking off/ putting back made better connection, or re-set the computer.. I can't find my gm book but if I remember right a code 12 is a nothing code. I hope it stays that way but would not go far for a while 'till I was convinced it is ok. Good luck with it.

1998 honda civic. car wouldn't start. thinking need gas. get gas. prime throttle body (maybe a little too much accidently) however, waited a day.(battery was dying from all the attempted starting. put an...

The only matter there should be in the throttle body is air. The throttle body in no way has anything other than "nothing" in it. The liquid you see could be the gasoline you threw into the throttle body.

Getting back to your problem. Do NOT have someone looking down the throttle body while you are trying to start the engine. That person may receive a haircut he will never forget! Get the battery charged. Try to start the engine because even though you think you put too much gas in the throttle body, it may start.

The tricky part. If the engine starts and runs for a few seconds, then you are having a problem with fuel delivery and that is the fuel pump most of the time but not always.. If it does not start at all, try one more time to pour gasoline into the throttle body, hold your foot about 1/2 way down on the pedal and then try again to start it. If it still doesn't start, it's time to check for spark.

Providing that your timing belt is ok and your engine tune up is such that the engine was running smoothly, you need three basic things for the engine to turn on. 1) Air and 2) fuel 3)Spark. To see if you are getting a spark, you can disconnect a spark plug wire from the spark plug and lay it next to the engine. have someone crank the engine over and listen for a spark sound. You will probably not be able to see the spark during the day. you can see the spark if it's dark outside. if you have a spark then connect the spark plug wire back to the spark plug. disconnect the hose from the throttle body. This hose comes from the air filter housing to the throttle body. Have someone hold the gas pedal down and spray some engine starter fluid that you can buy at the auto parts. Release the gas pedal, then hold the gas pedal down slighly and crank the engine. If the engine turns on and then turns off, check to see if you are not out of gas. if gas level is ok, your fuel filter may need to be replaced.

Cranks well but won't start.

Looks like you got spark, and gas in the throttle body made it fire: nice work.
Sounds like your fuel pump is out or the wiring is not turning it on. One way to be sure is to set a spare battery near the tank and hot wire the pump with jumper wires. Or if you have a voltmeter check for voltage at the fuel pump connector while the truck is cranking.. If the pump is working and getting gas to the engine, see if the injectors are pulsing. A good idea to check fuel pressure if the pump is working.

I let my truck run really low on gas in the cold and I think it may be frozen gas lines, the truck turns over but is not getting it's fire just thinking it might not be getting it's gas could I thaw it out...

Well, you need to check for spark and for fuel. To avoid wearing down your battery, I would put a charger or jumper cables on the battery as you do these tests.

You can test for spark this way. Pull a spark plug wire, and then insert either the end of a phillips screw driver or an old spark plug. Now, keeping your hands away from the metal, hold the screwdriver shaft very close but not touching an engine ground. Or, if you are using an old spark plug, touch the plug end to a ground. Be careful to have a very close gap to ground to avoid damaging your ignition system. Now have a helper turn the key to start the engine. If you see a spark jumping the gap of the spare plug or from the screwdriver shaft to the ground, then you know you have spark.

If you do have spark, then reattach the wire and try starting the engine again with a little starting fluid sprayed into the throttle body. If you don't have starting fluid you can also use a capful of pure alcohol or a very small anount of gasoline poured into the throttle body. Starting fluid is the safer bet. If the engine sputters and kicks over for a second, you know that the problem is fuel delivery to the throttle body, and it may be related to water in the lines (possible, but unlikely) or dirt and debris that clogged the filter from the low tank, or some other issue such as a bad fuel pump.

My 2001 Sequoia won't start. I poured gas in the throttle Body and it still doesn't start. How do I test the ignition coil? It does turn over! What else could it be?

If you tried pouring gas down throttle body then it would be a spark problem need a timing light or spark tester to see if the spark plugs are getting spark

Hesitation when Starting

Lets see if we can save you some money. Go to Auto Zone and by the spark plugs you self, they will have the step by step instructions to replacing the plug. Change them one at a time so you don't get the spark plug wires crossed and you only have 4 of them so platinum plugs will only cast you under $20.00. Skip the spark plug wire for now if there is no misfire. Pick up Throttle body cleaner too and clean out the throttle body, just follow the instruction on the can. MAKE SURE IT'S THROTTLE BODY CLEANER, NOT CARB CLEANER. Pick up also three bottle of fuel injector cleaner so you can add that to your gas tank for the next three fill up and might as well change the air filter. You may also want to change the fuel filter if you like and Auto Zone will have all the step by step instruction to all i have mentioned above. When removing the spark plug boot, it may be hard so by a spark plug boot plier so you don't damage the spark plug wire saving you $50.00. Try these simple things first since that is what's going to cast you $500.00 and after the cost of the spark plugs, throttle body cleaner, air filter, spark plug boot plier, and fuel injector cleaner. you should be around $50,00 in parts. That's $450.00 in about 1 hours worth of work, looks like you just made your self $450.00 in about an hour give or take a bathroom break. Good luck and keep me posted. Be glad to help.

The engine was rebuilt and now it turns over but wont start

Make sure your getting gas to the carb, or throttle body. Also check to see if you have fire going to the spark plugs. If you have both fire and gas, I would go through my firing order and make sure the plug wires are in the right place. You should also check your timing.

Wont start

Does the motor turn over? If it does, then you need to check to see if you have spark, gas and air. Check the air filter and replace if it is dirty. If the motor turnes over, remove a spark plug boot from one of the spark plugs and plug in a spare spark plug. Ground the plug on the engine and have some one turn over the engine. Do not touch the plug or wire when the engine is turning over. If there is no spark, I would say that the igniter in your distributor is fried or you may need to replace your plugs. Pull one out to see their condition. If you have spark, then remove the intake on the throttle body. Look down the throttle body and have some one push the gas peddal to the floor while turning the engine over. You should see fuel being injected to the intake. If you do not see any fuel, change the fuel filter if you have not done so recently. If the fuel filter has been changed then I would suggest a new fuel pump.
If the car does not turn over then check your battery voltage. If the battery is dead, it will not start. If you have 11+ volts then your starter is probalbly fried. Hope this helps.

Lost pressure in gas peddle

Hmmm well to start the pressure in you gas pedal comes from your throttle body, not your spark plugs. Secondly, there is only one cable going to your gas pedal, the other one is your cruise control cable.

Repair your throttle cable, or the spring on your throttle body is broken. it should be a fairly easy thing to fix.
