Hi all, I am new to the forum, but already am impressed with the amount of info I have found so far while troubleshooting this problem.
My wife drove her 2004 Chevy Aveo to work with no problems went to leave it wouldn't start it would turn over but not fire, 3/4s of a tank of fuel, had her check all the fuses, finally went and hauled it home on the trailer, now it is in the garage and this is where I stand so far.
I checked for fuel, and the fuel pump, all working as they should, to rule out the fuel I squirted some starting fluid in the air box (I know its not great for the motor but I wanted to rule out the lack of fuel being an issue). I took the cover off the engine and put my timing light on each, wire they all fire as they should, but it won't even attempt to start (turns over but will not start).
I looked through the past forums and double checked the timing belt vs ignition timing, that checked out.
History on the car isn't good, I bought it as a repairable and fixed it, with few if any issues (car ran great but had an error code for the emissions system), then the wife smashed it up again, so I rebuilt it a second time... since the last encounter the car has been running fine for 4 months... no issues, great car just under 70k... no I am puzzled...
The emission codes that used to be there are now gone when I put my code reader on ... the only fault I got was while I was working on it, it was the PC2610 pcm/ecm Internal Engine off Timer Performance on, but the door was open and the key was on for a long time, I reset the code both with the scan tool and then disconnected the battery just to be sure... still no fire... any suggestion would be great... one post I read on a different forum says with the PC2610 forum check fuses and relays (already have done that) then replace the ECM (I don't want to do that if I don't have to)... another says that the code is from leaving the ignition on for too long... any help will be greatly apperciated...
Thanks in advance,
