I've got a problem I've been working on and can't seem to fix it. I've got a 351w efi in my 90 lx. It's been about 8 years since it was last started and now it's not running 100%. I put a new fuel pump a week ago and it's holding steady at 41psi. The car will start and idle roughly but will rev up without any hesitation. The car seems to have a slight miss. It will run strong for a minute and then I'll shut it off and it won't start again for 20-30 minutes. I've pulled the codes and 8 different ones up. 51, 24, 31, 67, 81, 82, 85, and 84. I put in a new ect for code 51 There isn't any egr or smog equipment on the car. Is it possible the fuel injectors have gone bad from sitting for so long? I'm getting aggravated with the efi and I'm very tempted at this point to just go with a carb setup. Any help or questions would be appreciated.
