I have a 96' Astro that I am having a cold-no start/flooding situation! My question is, if the fuel pump is failing,....could it cause it to flood on cold starts? I have replaced the distributor,coil,ign. module,coolant temp sensor,plugs/cap/wires, new MFI Injector/Pressure Reg.,fuel filter ,Cleaned & checked the EGR! IfI mess with it usually for an hr or so trying to start it, It will usually start( I have blown off 5 new muflers in the last year with this! After I get it started & let it run for a while It will start the rest of the day just fine. But, Next morning(after it sits all night) It is the same problem( Flooding & just chugs & backfires sometimes! HELP!!!!!!! My curiosity on the fuel pump is because if I just jump in it & crank on it, it will not even fire,....If I wait the 2 seconds for the fuel pump to stop, it will at least chug( but not start) ! Tapping the key repeatedly for 1/2 an hr or so, is usually the only way i can get it running!

- Actually,..this does not have the "NUT KIT" Like I believe you are thinking, it is just the steel lines into it! I have replaced the injector with a new Upgraded injector & Pressure regulator! everything on it is new( every sensor ), I am just baffled at what could be the problem as it runs like a TOP, when I finally do get it started, & starts/runs fine all day until i let it sit overnight! Also just to bypass most peoples next thoughts, it does have( 3rd set we have tried) AC Delco Cap/Rotor/Plug Wires,...& 2nd set of New Bosch Platinum Plugs ! I am thinking from a couple of threads I have read, it is the fuel pump! I have heard from a couple of people, that if it doesnt have the appropriate amount of pressure, it will not fire correctly. Its Turkey Day, I am going to buy a fuel pressure guage in the morning,...I will post what I find! *** Anyone has this same problem & have cured it, or has any ideas, PLEASE feel free to email me on this! I AM TIRED OF FEELING BEAT! LOL
