YOU MIGHT WANT TO START LOOKING FOR AN INTAKE GASKET LEAK, NOT A FUEL DELIVERY PROBLEM

Remove Your Air Filter, If You See A Liquid Squirt or bubble up, Or smell gas, then its the plugs

What is the problem? Why are you limiting the problem to those 2 areas of concern?

If it is the electronic fuel pump that is the problem you will not hear the fuel pump humm as you turn the key in the ignition. Replace the fuel pump which is located inside the gas tank.

after you have replace the pump and it doesn't humm what else could be the problem

the fuel pump could still humm but it could be weak. there is a pressure valve on the fuel line behind the intake. put a pressure tester on it. if it is over 45 lbs. then your fuel pump is ok.

how do you tell if your fuel pump is working

try bypassing the fuel pump, and directly injecting fuel, this will tell you if the problem is the pump, the lines, or further ahead

You need to tell us what the problem is(wont start, backfires,etc.)before we can give you an idea to try.
