08 Cobalt ss lnf crank no start ( SOMETIMES )
Hi all thanks in advance for any any responses :
Got an 2008 cobalt turbo and sometimes it just cranks and wont start other times its just fine.
Turn the key on and off a few times and that will work most of the time and other times just let it sit for a few minutes and then try it normally starts.
Usually if it starts once it starts again with no issues if its warm ( I guess you can call it)
Sometimes it has a slight backfire after cranking and turning the key off and it will start.
I "primed" the car one time with gas and it started but im unsure if it was just a coincidence or not will have to try again
Fuel pressure seems good
Any advice will be appreciated. Thank you

Try unplugging the EVAP system and see if that has an effect. The EVAP system crapping out can sometimes cause a long crank issue.
You also need to actually get data on the fuel pressure from the hpfp and the lpfp

How do you get data from the fuel pumps?
About a month ago I changed the intake actuator with a used one because I had I code for it ( p0343), could it be related ?

Evap system seems fine will test further this weekend

Yes turning the key on off works sometimes, when it doesn't it will eventually give me a backfire so I am guessing no spark till then.

Have you checked your evap purge solenoid?
