2004 Aveo won't start Help.

[aldnaiels1989]

The starter is working and good to go.

I will try the starter fluid. I just didn't know where to spray it (In my neon i had a carburetor). When I hit the gas while trying to start it has a very VERY small cough to it but still not start up.

Its 167k on it. I haven't changed the timing belt on it. hmmm....

So , starter is working ?

For a car to run , it has to have air , fuel and spark . Air , it probably has . Fuel and spark ( spark also has to happen at the correct time ) , I do not know .

Take the top off the air cleaner box and remove the air cleaner . Spray a TINY amount of something flammable , in the tube going from the air cleaner box to the engine . Ideally , starting fluid . But be very careful , some starting fluid used to be ether . Do not know if that is what is used now . But ether is very powerful and too much can be disastrous .

Quickly , before the starting fluid dissipates , try starting the car . If it briefly starts or coughs and tries to start , I would say you probably have spark , but not fuel . If it does not try to start , you probably do not have spark .

You said some one told you it is possibly a sensor . Trouble is , there are lots of sensors on the engine and transmission . There are even sensors on the exhaust system .

How many miles on the car ? Has the timing belt ever been replaced ?

Report back with more info .

God bless

Alrighty then I will follow your orders !! Sorry to have you repeat!! lol

It is a 04' It does have a throttle cable.

I'll get back to you on the ECM. My check engine light isn't on so I didn't think to try to have any codes ran.

Not to be too redundant, but I would check the battery, and grounds, especially the one that bolts to the bottom of the engine as there are many ground circuits that all terminate under the engine, and again under the battery. Do a search for 'g103' and you should find chatter about it.

So take a flashlight and slowly go over every wire you find, trace it to it's ground point, and make sure nothing was missed during the other work.

This is an 04, so it should have a throttle cable correct?

If everything seems good wire wise, you can always do the old school method of; pull a plug, ground it to the engine, and check for spark as someone turns the key. This would tell you if you have spark at least?


Without seeing the car I can only lend these guesses. lol Keep us posted. What has the ECM reported if anything?? Any codes? Any power at all to the ECM?

If the timing belt hasn't been changed I would remove the oil filler cap and wach the valve train as someone cranked it over... if the cam is not rotating the the belt broke.

167k on the original timing belt . That sounds a little scary .

You could check for spark with a tester .
