Start stall..issue..
Well I'm posting once again in hopes of possible suggestions on what might be the issue...
When the weather is warm..(above 45*f ) the car starts fine...when the temp is lower... The car will fire right up then immediately stall...then when I fire it up again it runs perfect...
No codes... No issues when engine is warm or cold... Seems to only happen when ambient temps are below 45*f..
I ran a data stream this morning.. Before starting Coolant temp gauge was on with ambient temp 50*f. Manifold air temp registered 10* higher (60*f)than coolant temp... Could this be an issue??
Is the ECM able to reset parameters.. After the car fails to stay lit the first time......seems strange that it always lites and runs fine second hit of the key...
Thoughts opinions..
Car runs great otherwise.....

Just a shot in the dark, run a fuel pressure test. I had a little trouble cold. the pump went out and now the car starts with 1/2 turn of the starter and runs strong hot or cold.
Good luck
