Question about Chevrolet Aveo
Hello, See you had some big problems with your car. You need a really good scanner for this. I know Autozone and Oreillys will scan your car for free. You may pick up a little help there. Before you go, check your intake manifold with a spray water bottle around the seams of the intake and any vacuum fitting. Do this with the engine running.
With your intermittent starts, the flying belt may have damaged a crankhaft or cam sensor. When you rebuilt your motor you had to disconnect some of these parts. The injector pulse problem would seem unrelated to a broken pulley. If the engine ran good before it blew up, the fuel pressure, injectors , and so forth are the same as before.
The TPS, throttle position sensor regulates spark and fuel. Its a cheap part to try. After that, I think you need a Dealership to reprogram your onboard computer. Their computers can electrically read and time the engine.
Most handheld scanners can only read info, not change anything. I hope you did not have any damage to the pistons as they hit the valves. You may want to do a compression check if the electronics do not help.

There is a simple way to check the timing - once it's running just keep your timing check tool nearby and check it then. If it is in their shop it is sticky but - your insurance would pay for a tow to another shop to be checked only and then most likely pay for it to be returned to the original shop.
I am thinking with you because had it been the injector for any reason it would have shown up long ago.
I am 90% sure you're right but the place it is now is beginning to stink as their not standing behinds their work. You can run a check and get it to throw a code ASAP if it doesn't throw a code then something is up. Also just do a visual for ALL the MAF connectors and also the plug wires you can get to that might short out or their respective one to one [ from coil 1 to plug 1 ] is out of order.
I think this is for sure a timing problem and the shop may be covering their mistake. I would **** it up and move my truck to a shop someone recommends.
