changed the fuel filter?

any codes?

[mtatsch]

bone stock, fuel filter just changed, and i dont know if there is any codes or not. Is there a way so I can check for codes on the odometer?

 

[WUnderwood]

look in the owners manual, you can cycle the key 3 times, and the code should show up on the odometer

hope this helps

injector tubes, lift pump, relief valve, and injectors can cause these symptoms
