Question: Hard starting when cold ?

[killain]

I have a 2003 LS1 and it's becoming a problem starting when cold, ( right now it's 75 degrees) The enging has to turn over for 20 seconds before it fires up. The problem goes away once the engine is fully warmed up ? No I haven't taken any codes so far, I'm disabled and taking the codes isn't something I can do. Thank you !

Hi there,

Check to make sure your MAF sensor is completely connected to your engine.

Also, have you run any Techron Plus through your fuel system recently or do you use TOPTIER fuels ????

Any modifications ?????
