Ever since ive had the car its had a starting problem. It takes about 5 seconds longer than it is supposed to to crank before the car will actually start. After the car has been sitting for a few hours or more the car will start up just fine but after sitting for just a few minutes to an hour or even after putting gas in the tank the car wont start at all it will just crank. So I would have to manually push start it.

I've been told recently that it has something to do with the fuel. My plugs are new and my fuel injectors are aftermarket. My uncle is a mechanic and he probed each of the injectors and said that they were all fine except for #1 which was a little loud until he moved it around. I had a friend who mentioned it might be my coils.

I am getting horrible fuel economy and my car idles funny sometimes.

I have these MIL codes I got from Autozone if these would help to find the source of the problem:

P0300: Random Cylinder Misfire
P0301: Cylinder 1 misfire
P0304: Cylinder 4 misfire
P0135: Sensor 1 Heater System Malfunction

I most likely need just an o2 sensor for the last code since it had oil all on it from when my turbo started leaking.



Thanks to all that can help!!

 

Check your spark plugs and coil packs first. How much oil are you burning? I think you may have a bent valve if your plugs and coils are a ok, with that being said, if you're burning more than 700~ miles a quart of oil, schedule a compression and leakdown test, definitely check the coils

 

Check your fuel pump/pressure and fuel lines. Check spark plugs. Make sure you have gas. Make sure all your electrical components are properly connected.
