Stupid EFI

[AF-1984]

I think the injectors need to be cleaned. It will start on the second pull. It will then run for aproximately 30 seconds. However during that time I am unable to apply any gas from the throttle. After the 30 seconds, it will stop running. I am then not able to get it started for at least a couple hour period of time. Does this sound like the injectors? If so, how big and dificult of a project is it to clean them?

Thanks

What is the year and make of the sled? Is it batteryless EFI or does it have a batter? Do you run injector cleaner through it ever? Do you stabil or Seafoam the gas at the end of the season?

It is a 1994 Indy 500. I just replaced the battery. I ran a bottle of seafoam through earlier this winter when the sled was running. It is all new gasoline so there was no stabil in it.
