No, this is not closed.

you need to replace that CAT ASAP or you will be slowly ruining the engine.

The universal cats cost about 70-80 bucks and it should be done soon.

I bought one yesterday. Spoke with a shop and next wednesday is the earliest they can do it. I did drill a couple holes in the front flange of the old one. It runs 90% better but still stalls at lights some of the time. Thanks I did not know that would do that. What does it do? (can you tell I'm an engineer) My guess would be to foul up the exhaust and EGR areas.

It will put too much back pressure on the valves and could cause them to not be able to close, having them float and causing damage.

Hello,

I Would Not Buy And Replace The Fuel Pump Yet. I Had A Very Similar Problem With My Truck. Mine Was The Ignition Module Under The Distributor Cap. It Only Cost 30 Bucks And Is Alot Easier To Replace Than The Fuel Pump. The Ignition Module Is What Tells The Injectors When To Open. So If You Have Fuel To The Injectors And No Spray That Would Be The First Thing I Would Look At.
Mine Was An Intermitant Problem. Took A Couple Hundred Bucks In Parts And Alot Of Cursing To Figure It Out.
