ok my car was overheating due to a busted hose... i got it home changed the hose but the car didnt want strt. so i jumpsarted it wit another car and it started. n a few min later i tried to start it again and it wont. i think it only starts wen jumpstarted, what are the possible causes??

 

Dead battery?

 

but it cranks!!
the battery doesnt sound like its dying!
but i can be wrong..... right?

 

Listen for priming of the fuel pump -- no priming would likely indicate a main relay problem.

Check for spark at the plugs - no spark would likely indicate a coil or igniter problem in the distributor.

Neither spark nor priming -- check for a loose/corroded ground wire on the thermostat housing.

 

i dont get"listen for priming at fuel pump"
and checking for spark.. exactly how do i do that?
sorry im juss learning lol
appreciate it

 

Fuel pump: Listen very carefully as you turn the ignition key to ON without cranking the engine. In the rear of the car around the gas tank, you should hear for about 2 seconds the low humming noise of the fuel pump priming.

Spark: Uncouple a plug wire from one plug and insert a spare one in the end. Ground the threads of the spare plug on a convenient metallic engine part like the valve cover. When a buddy cranks the engine, look for a bright bluish spark at the tip of the plug. Repeat for remaining plugs.

 

i dont have any spare plugs tho!

 

ok i got it to start... but now its revvin like 1200 to 1500 rpm.. idle what can that be?

 

when u replaced the coolant u didint do it right and now u ahve lots of air in the coolant u need to bleed the air out.. the extra air is throwing off the ecu

 

You know where the bleed screw is?

follow the top radiator hose back to the head. You'll see a bleeder screw on top of the water outlet neck. open that slowly while squeezing the radiator hoses. and keep topping off the radiator.

I have learned how the raise the right front of the car while filling the radiator to get most of the air out.

Oh yea, clean your battery terminals

 

5th generation Civics have a bleeder bolt but 6th generation do not. If you have the latter, then fill the radiator and reservoir with 50:50 coolant (not water) and put the cap on loosely. Idle the engine until the radiator fan comes on twice. Top off the radiator and reservoir and you are done.

 

what would happen if i use water (lack of transportation for 50/50)

 

Use of water in the cooling system is a very bad idea as it will promote corrosion that will eventually destroy the engine. Other benefits of coolant include lower boiling and freezing points.

 

thanks for the info!
i appreciate it !
now oone more thing lol
to flush out my cooling system .. how is that done.. like proper procedure frum start 2 finish.. thanks

 

coolant gives use higher boiling points not lower. water will not hurt if you use it temporarily but you might as well just put coolant in it because thats more work for you later if you dont

Thanks for correcting my obvious mistake.

 

your welcome

 

thanks for the advice guys...
will do.. as soon as u can tell me how to flush and how to refill properly(just in case i dont do it right)

 

What year and model engine?

 

95 civic coupe. gotta d16z6

&gt; Open the petcock (plastic screw on bottom of radiator)
&gt; pull off upper rad hose
&gt; disconnect lower rad hose from thermostat housing
&gt; put garden hose into the end of top rad hose and turn - just water
&gt; take rad cap off
&gt; turn car on, turn your heater on and turn it on HIGH, you need the water to circulate and flush out the heater core
&gt; let the water flush through the system and straight out the thermostat housing
&gt; When you're sure there's only clear water coming out, you can turn the motor off, let it drain, etc. - make sure you clear the radiator out too (it'll drain right out the bottom since you opened the pet ****) and that both rad hoses are cleaned
&gt; reconnect everything and fill it up with the car running (or you'll be low) with a 50/50 mix

Some people "frown" at this idea - but it works 100% of the time - so take it and run with it.

EDIT:
PS: The chance that an air bubble is causing your bumpy idle is highly unlikely, but instead of flushing the system (which isn't really needed), just start the car up, top off the radiator to the neck and leave the cap off - all air will eventually bubble out...I doubt it'll make a difference on your idle though..it's most likely a vacuum leak, clogged FITV, or bad/clogged IACV.

 

thanks again guys!!!
