Don't think so. What MD is asking about the color of the spark, if it isn't blue or white. Unless you have a check engine light you won't have a code. No code likley it is a mechanical problem. Pull a couple of spark plugs, post back what they look like.

 

OK so I hooked the fuel gauge up while I was at work and when I came out 8hrs later the fuel pressure had dropped to 20 psi, but it still fired back up to take me home. So I let it sit all weekend and my driveway has a slant leaning toward the street. Come Monday morning it wound not fire back up. So my question is the fuel check valve in take sending unit or is it part of the fuel pump?
