2003 Malibu hard starting
I've got a 2003 Malibu that will start up hard sometimes in the morning and all of the time after about 3-4 hours of sitting. The fastest way to get it started is to crank the engine for a few seconds, shut the key off, and crank for a few more seconds, and it seems to fire up. I've swapped the fuel pressure regulator out twice, fuel injectors (re-man) twice, and also have changed the fuel filter. The car runs fine, but it seems to be lacking torque, but I may be just expecting too much out of it. The engine runs smooth however. Fuel pressure is at about 65 running and 70 with no vacuum on the regulator. I however have not checked the pressure after it has been sitting. Once the car shuts off, the fuel pressure drops from 65 to about 42 and seems to stay there, although I've only watched it for about 15 minutes. If anyone could help me, it'd be appreciated since I've already stumped one local garage...
Also, the check engine light is not on..
