If you have tried to start it enough the not running will positively wet the plugs out to then not start easy and die easy. Pull them to see if they are wet. Your perceived rich issue, ALL cars start rich but go to running fast enough to burn the plugs off clean, if they cannot run due to other reason the plugs quickly wet out. Then car only runs like crap for a second to die even if nothing is wrong with it. May need more plugs.
Got it... but car starts every time still run for only a sec.
Next thing ill try is, unplug or remove fuse from fuel pump and try to start on ether (starting fluid). If the engin will run on starting fluid, than gas is contaminated.
If not, there must be electrical issue... because engine stall so fast, i dont think, there is vacuum problem.
