Something else you could try. get some starting fluid and spray into the throttle body. If it starts, you most likely have a fuel delivery issue. If not, it's something else causing it not to get spark.

I got an after market stereo and the antenna is hooked to ignition (great job install guys). Alright fuel pump is doing it's job. I am going to jump to the sensor issue next. I was told by a guy at American Corvette (I live right beside the shop) that the coolant temp sensor can go wacko and send bad info to the computer, causing it to dump fuel in the engine and causing it to flood (I am definitely smelling that). So the coolant temp sensor is supposed to get the engine into that "closed loop" Muffin was referring to...but it's not doing its job if I am getting a code. Going to get a new one now. And I will pick up some starting fluid/spray.

My 1992 Corvette ran fine before I parked it for the winter. I recently went to start it and I am having some issues. Initially, it fires up with no problems, but begins to idle rough. I almost have to keep pressure on the gas to keep it from bogging out and stopping. After a minute, it will idle itself...although still rough. The big issue is, like clockwork, it cuts completely off at about 5 minutes into idling and will not restart. It takes about an hour for it to start again and it will do the very same thing. I ran codes and got a 15 - 43 -and 26. I just wanted to get some ideas from seasoned people before i go replacing every possible thing i can think of. I already got fuel filter and plugs...thinking fuel pump this weekend. Any ideas or help would be awesome.

Guys thanks for all the great help! I replaced the coolant temp sensor and purge fuse. Bingo! Running like a charm. 5 minutes and done. Going to address the other code next...43, but as of now the red 92' is zooming. Just opened her up on a spin around the block with my wife.

I would start here, and then check the rest of the items as indicted.
Clean out the throttle body with throttle body cleaner. Clean the air passages for the IAC and possible the IAC also. However I would not be surprised if the IAC is bad now just from sitting and absorbing engine fumes from crankcase and or moisture.
I know some of you northern guys store the car in the winter and in view of the weather I've seen I can't blame you. But the worst thing you can do sometimes is store cars that are 15 years old with sophisticated electrical systems and older seals. Maybe the newer C5&6 would hold up better but I really think the C4s need to be driven. I keep reading these stories of problems after storage.
I wish I had a great inspired answer or had wonderful direction. Maybe can't drive the car in the snow or cold weather but I think 8 months of sitting is worst than driving, got to get it out at least some.

Clear the codes and see if the 43 pops back up. It may have popped up due to the other issue.
I know I couldn't have done what I've done to my vettes without this forum. Lot of knowledge here!
