My 2004 chevy aveo 5 door will die while i'm driving. I will turn the key and engine will turn over but not start, after about five min. of this the car will start and i'm able to drive for about two min. and will die agian. Checked coeds from engine light and P0700 and U2105 will show up. Engine light has come on and off several times. The fuel pressure ragulator is working fine and so is the fuel pump. Please help.
There is a Communication problem between the Transmission Control Module (TCM) and the Engine control module. That is the bad news and is why it's shutting down the engine.
The good news is i believe there is a TSB recall on the 2004 - 2007 chevy aveo for the P0700 problem so it should be covered under warranty.
Believe the TSB# 05-06-01-030D
Good luck and hope this helps and hope it's not a bad ECM. Check the wire harness to the ECM and TCM, look for broken wire or the harness it self gone apart.

Connecting it to a scan tool will give you the answer in the form of codes, AKA DTC codes. The engine light is the clue, the scan tool tells the answers via the codes. All the codes are online.

Do you hear the fuel pump running when you turn the key to on? I usually open the fuel filler door and listen while an assistant turns the ignition switch. It should run for a few seconds.
there is a Technical service bulletin for this problem, the number of the TSB is 01575, TSB Date:January 1, 2004
It has to do with engine valve seating problems.
Daughters 2004 Aveo stopped dead on freeway. Plastic thermostat on engine and melted off. Chevy said it blew the engine, searched on line and found 17 pages of same complaint. Chevy repaired car for free. Still not worth the worry. But if this is your problem, fight it don't pay for repairs!
