corsa c wont start when cold

[wizz2c]

here's one for for ya all..

corsa c 1.0 12v
2003

car came in as non runner it was quickly diagnosed as siezed fuel pump. it as been sat in body shop for six mths maybe the reason?? anyway after the pump was replaced it would not start unless started with easy start then ran at fast idle till running temp, only then would it idle on its own,came to it this morning and the same synario occured. i ran live data and all seems well ,first thoughts was the coolant temp sensor but this reads perfect in live data as does the rpm. any thoughts??

if you don't have trouble code, you have problem with fuel, check fuel presur and injectors.

thanks i'm with you on the fuel pressure this was also what i was thinking but sort of ruled it out coz brand new pump fitted .

[wizz2c]

sorry failed to mension it starts perfect once it is up to operating temp if this affects your thoughts

Definetly a CO'2 sensor problem.

Could be air leak.

Does the diag not throw up any errors whatsoever?

[wizz2c]

funny you say that,, lambda sensor was a fault code on the first dtc check and thereafter totally clean no dtc's

[obdmaster]

car when cold isnt in closed loop, so its not taking any inputs from lambda. Id of thought fuel, drain tank , clean system fresh filter and fill with fresh m8.

agree 100% with above poster, ask if supermarket fuel with it's 12% water.

fuel mayte hace FUEL gone stale, (pushed for timwe)

pitty id not read this today , i thought of bad fuel being the the problem late today thats after messing around with the fuel pump againto check if id fitted something wrong. the tank was almost empty (and i mean it was running on memories)so i cleaned the tank added new fuel and hey presto all is well. thanks to all that contributed to this thread.
