SOURCE: diesel engine keeps stalling
Looking at the brief description of your problem it may be your heater plug timer? when you start the vehicle from cold the glow plugs have to heat up. These are little pencil type plugs that are mounted in the cylinder head they are timed and glow rather like the bar of an electric fire so the hot spots in each cylinder warm and give precise combustion. If the timer/relay gives only a short burst of power your car will start as normal but if the cylinders are still cold/cool when it shuts off the Vapourised Diesel doesn't ignite correctly so rev's drop and if you can't raise them will stall. When you turn off the ignition and back on again the timer/relay kicks in glow plugs glow and bingo your'e off again. I presume after the first stall everything is back to normal? if not how far up the road is it before engine dies? also how long after starting does it stall?
I hope you don't mind the Epic, Oh! if your 306 continues try starting the car and waiting a while listen for a click like a switch or if the interior light is on when it brightens after a few seconds turn off the ignition then back on and start then see how far you go!

Hi You need to get the ecu checked for fault codes if there are none it is possibly low fuel pressure you should allso check this have you changed the fuel filter or opened any fuel lines this could introduce air
which will lower fuel pressure.Good luck Chris.

Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

check tps sensor (throttle position sensor in backside of the throttle cable) and map sensor (manifold absolute pressure on front little 1 inch sensor with vacuum line) make sure there plugged in. the ecm (engine control module driver side inner fender) and tcm (transmission control module under dash) both need the data to know when to upshift and increase fuel/air. Otherwise the computer runs default values and guesses off of other sensors giving poor performance. also disconnect battery for 15 min. usually resets aveo service lights if you dont have a scanner.
