I have changed my crankshaft, camshaft, fuel line, fuel injectors, spark plugs, and the coil packs. After changing each part the car would start up fine for few hours. But when I try to start it the next day, it wont start. When I crank the the car I can smell a strong fuel smell. Any idea what could be wrong with it? Or where I should begin looking?

Hello,

This could be a problem with an o-ring on the fuel injector. Each fuel injector has two o-rings one on the top and one on the bottom. The o-rings are like little gaskets and seal each end of the fuel injector. Sometimes one these o-rings does not seat properly and it will leak fuel. Also, I would double check the fuel rail where the fuel line coming from the tank connects to it. I have included in the diagrams down below the locations of the fuel hose and fuel rail as well as the different types of fuel line quick connector used in your vehicle. Please check these out and get back to us with what you find out.

Thanks,
Alex
