2004 chevy aveo, Will not start because injectors are not opening to apray fuel. Can spray carbureator cleaner in air intake and it will run. Have had this problem before with GM cars and think it is an anti theft problem. I understand there is a way to reset the system. Can you give me the procedure that will reset the system?

When taking battery cables loose, I try to use memory saver. Hoping there won't be any problems on start-up? Are you saying the starter motor cranks good, but, won't start? If so, have helper crank it, while you check for spark at the spark plugs--check proper fuel pressure--check fuel injector pulse. If the starter motor won't even crank, then have to check voltage and ground for the starter motor. Any starter testing, make sure tranny is in park or neutral and functional parking brake is set.
your anti theft device is activated,you need to lock and unlock your doors a couple times with the key fob,not the key,and then you need to put the key in the ignition and start it,if you dont have your key fob,call your buick dealer to get a new one,they are programmed for each car only,you cannot bypass it.
Hi Jonathan, Make sure you have injection as well as fuel in the rail. Sometimes the anti theft unit will cut the injection and therefore the vehicle cannot start. have the vehicle scanned and then rectify what ever defects and faults show up. Another reason for nil injection could be a defective cam or crank sensor. Sometime removing and cleaning them will work. Regards John
When you chaged the air filter & sprayed Gumout carb cleaner, you got rid of a little gunk in the air intake, but when you added the fuel injector cleaner (its the same stuff as carburator cleaner) to the fuel tank, you "cleaned out" ALL the ****/gunk/buildup/dirt in the fuel system which has built up since 1991 and sent it straight to the fuel filter, which is now clogged. The reason that the car tries to start, but fails, is that it'll successfully burn up any fuel that gets past the clogged fuel filter, but the engine consumes that small amount of gasoline quickly, then dies. Your solution: change the fuel filter. The fuel filter is located: Under vehicle, driver side, below seating area, near fuel tank, mounted on frame rail in fuel line
email me. Check and make sure all vaccum hoses are not cracked. Basically anything connected to you throttle body, or intake that is made of rubber replace it. there is a small crack. happened to me this week. small air leak makes a difference. also if you can replace the intake with a cold air intake. Runs way better.
I had the same thing happen with my 2004 Chevy Aveo, but I drove it appx 3 hours with my hose broken and, evidently, cold air and dampness allowed ice to build up and they tell me thats what made my throttle plate stick 3/4 open! Dont know it you may have done something to the engine or not, but this definately can be quite dangerous!
There are two kinds of injection... throttle body looks like a carburator, and has one or two injectors in it,
Multiport has an injector for each cylinder. A multiport wont have a throttlebody, but both do have other parts, like an idle air control valve, and other items that could be cleaned.
I would recommend adding injector cleaner to the fuel, and spray some carburator cleaner into the intake while running. Just an idea!
Start with replacing the fuel filter. The Aveo fuel filter is located passenger-side rear, in front of the
If there is no filter there, then the filter is a non serviceable filter and is integrated with the fuel sending unit. Your going to have to replace the fuel sending unit if the fuel pressure is slow, start with running fuel injector cleaner through the fuel system for the next few fill up's and hope that will clear up the issues your having.
The other thing to is that your IAC (idle air control) valve may be dirty and is stuck close, you can try cleaning it by spraying Throttle body cleaner through the throttle body, paying attention to the IAC passageway. A dirty of faulty EGR valve will also do the same thing.
Start with the simple and inspect to see if you do have a external fuel filter, and inspect the wire leads to the IAC, EGR and clean them with throttle body cleaner. Don't forget to run the fuel injector cleaner through your gas tank.
