94 Sierra starts then stalls
How did you end up fixing it? Having the same problem on my nanas ‘94 Sierra with less than 300 k KM on it, owned it since new and always up to date with maintenance. She was driving home the other day and it just died. Was able to start it up and drive it home but now it starts and dies seconds later. Thought it might be the alternator without looking into it too much and replaced it but it’s still doing the same thing. Was it your fuel pump?
Same deal on my 94 k1500. Just bought it a week ago. 4k miles on rebuild. Engine tranny transfer case redone. Everything but the little things. Ran like a champ for a week then it started surging untill it stalled out on idle, especially if lights+turnsignals on. Unplugged IAC ran good for a day then back to the issue. Changed that out, it ran about 20 miles fine then, back to the same idle behavior. Noticed the rattle in the catalytic, changed it to magnaflow. Felt better driving, when in idle, same problem. Checked fuel pressure and it found to be low. Changing out fuel pump today. I'll update you after its installed.. In the end hopefully having all the little things updated also will keep this beautifull heap going another 200k miles.

Will be interesting to see if anyone from 7 years ago answers.
Regardless, I’d say first thing to check in cases like this is fuel pressure. https://www.chevytalk.org/fusionbb/s...php?tid/253427
