Looking for answers, any ideas are appreciated...
My 2004 TJ Sport has trouble starting when cold. It cranks a couple of times before turning over. After running for a bit, if i don't let it sit for too long, it starts up quick, no problems. It was throwing an engine light and a P0301 code.
Per previous research and advice, I just replaced the entire fuel pump assembly module (which i'm told includes the fuel pressure regulator). then disconnected the battery for a bit to reset the code.
The jeep's running smoother (so there was probably a fuel pump problem too), but the slow start issue remains.
Anyone have an idea on what it could be? O2 sensor? the fuel pressure regulator on the fuel rod? spark plugs? Fuel injectors?
Thanks for the advice.
