So I have a 2008 cobalt, and its winter here and everyday its cold outside my car sounds awful starting like its not going to but does, and if I drive it without it being warmed up a lot she stalls out when I stop. This only happens for the first few minutes until the coolant warms. SO, I checked the fuel pressure while engine was running, got 60 psi, shut off the engine and pressure dropped to 40 psi. Do you think the problem would be in the fuel pump?
HELP!
