spider

[Rcfan]

I have a bad miss all the normal has been changed. Cap, rotor, wires, etc.
is there an easy to tell if the spider assembly is bad without pulling upper intake?

I pulled my throttle body on mine, and jumped the fuel pump so it would stay on and got a small mirror and a flashlight, then looked inside the manifold to see if there was a leak. That worked good. I could see inside the intake very good with the mirror and the flashlight. Also a fuel pressure test may help. Jumped like I'm talking about, it should be over 60 PSI with the truck not running. Here is a grate video on testing the fuel pump. It is a long video, but it tells you just how to jump the fuel pump relay to make the fuel pump come on and stay on so that you can look for any leaks on the fuel injectors, or spider in the manifold.http://www.youtube.com/watch?v=McnXLcJNVfI&list=PL6677A5143AA84FE9
