You undress the top and front of the plenum and unbolt it and lift it off- do you have symptoms of a bad spider assembly- or a leak down?

Check fuel pressure and leakdown before you take anything apart. It will tell what the problem is and save you a bunch of time and money. Key on, engine off, fuel pump running, fuel pressure must be 60psi to 66psi. Must remain above 55psi for 3 to 5 minutes after the pump shuts off. Post your results.
